    Heloísa Marinho, Celina Airlie Nina, Nazira Féres Abi-Sáber and Odilon de Andrade Filho have a range of bibliographic production, and research articles regarding the understanding of the child under 06 years in Brazil. Anchored directly to government agencies of their period, the authors sought to present their works in pedagogical ideas for the Early Childhood Education. Faced with this observation, we aimed to understand: The conceptions that concern the School movement would have been appropriate in Brazilian Early childhood education? How the ideals of John Dewey were implemented for the education of children under 06 years? So the main research hypothesis is the incorporation of educational ideas of John Dewey occurred in the core of the hygienist/assistentialist movement, which could have led to distortions and theoretical and methodological mistakes in the use of the Dewey school theory. Thus, our objective is: apprehend and analyze how the educational conceptions of John Dewey were appropriate to "think" the Brazilian Early Childhood Education from to 1934 to1971. As methodological procedures we base our analysis on the theoretical and methodological support of Depaepe (2000; 2005) and Certeau (2008) with regard to the consideration of the research object in its historical context, but also consider the assumptions highlighted by Depaepe (2000; 2005 ) on the "black box" of the classroom, "grammar of schooling" and educacionalization process. Therefore we conducted a literature review about the output for the children under 06 years, considering the period defined for this research. This survey, however, was made in the following journals: Revista Educação, Revista Sociedade e Educação and Revista Brasileira de Estudos Pedagógicos. Regarding proposals to lower education than 06 years in Brazil, it was possible to understand the political and pedagogical demands for this field. In this sense, we sought from the selected material understand the circularity of the ideas that were present in the context of life and production of the four authors selected as the object of our study. Heloisa Marinho, Celina Airlie Nina, Nazira Féres Abi-Saber and Odilon de Andrade Filho highlighted by the direct relationship with government agencies set up at the time to provide the shelter, protection and educational projects for young children in Brazil, among which out: the National Department of Children; National Institute of Pedagogical Studies (INEP); Brazilian-American Assistance Program Elementary Education (PABAEE) and the Center for Studies and Research Helena Antipoff the Pestalozzi Society of Brazil. These authors can be considered active and immersed in national and international debates in the field of Early Childhood Education, with: materials, discussions, guidelines, analysis and activity descriptions for the children. From the analysis of all this material it was found that the set of conceptions present in the New Education ideas were appropriated by these authors, but were used as species of "slogans" that represented the ideas of Dewey, Decroly, Montessori, Froebel, Pestalozzi and Claparede; these appeared as a discourse of "reform" and consequently thus "improving" for the Early Childhood Education.

    The use of precast concrete system in multi-storey buildings demand for structural solutions that enable its horizontal stability without implicating the architectural and economic aspects, its challenge is borne by the structural engineer, who often need to assign additional structures (substructures of bracing) that provide the rigidity necessary to ensure the overall stability of the assembly. This study aims to analyze and evaluate the technical and economic performance of bracing systems applied to buildings with multiple floors with precast concrete structure and can be justified by the current need to develop appropriate technically ways of choice in the constructive system. The development of this study is the analysis of global stability in multi-storey buildings with the application of bracing systems, evaluating the influence of the stiffness and the arrangement of these elements in the performance of the structure, and comparing the concrete consumption values of the structures formed by beams and columns (disregarding the slabs and the foundation), and also values of the efforts in the foundation. To develop this study we used the commercial software STRAP® as a support tool for calculations, where the results gotten by it, showed that the bracing substructures improved the behavior of the structures analyzed in the issue of global stability. Finally, they were provided the necessary subsidies for the proper choice of the wind bracing system to be employed on the structures analyzed in this work.

    This work reports studies of in vitro metabolism involving the compound 3-(2-chloro-6-fluorobenzyl)- imidazolidine-2,4-dione (LPSF-PT-31), a new 2-adrenoceptor agonist and, studies of enzyme phenotyping of montelukast, a drug used for the treatment of asthma. The results of this study revealed that LPSF-PT-31 is metabolized via CYP P450s in rat and human liver microsomes, producing only one major hydroxy-metabolite. LPSFPT- 31 showed a higher rate of in vitro metabolism in rats, which suggests a greater exposure to the drug in humans. The structural identification of LPSF-PT-31 metabolite’s was achieved through LC-MSn and 1H-NMR analysis that provided data to conclude that the hydroxylation occurred in the 5th position of the imidazolidine ring yielding to the production of 3-(2-chloro-6-fluorobenzyl)-5-hydroxyimidazolidine-2,4- dione. Related to the studies of enzyme phenotyping of montelukast, it was observed that the glucuronidation is the main clearance pathway of montelukast accounting for ~85% of the total apparent in vitro Clint (CYPs +UGTs) and that the CYP-mediated oxidation accounts only for ~15% to the overall metabolism of the drug, being montelukast acyl-β-D-glucuronide and montelukast 1,2 diol the major metabolites formed via UGTs and CYPs, respectively. Kinetic studies, correlation analysis, inhibition studies and, experiments in expressed CYPs and UGTs revealed that the CYP2C9 and CYP2C8 are comparably involved in the formation of montelukast 1,2- diol. CYP3A4 was responsible for the formation of 21(R)-OH montelukast and 21(S)- OH montelukast, while multiple CYPs catalyzed the formation of 25-OH montelukast (CYP2C8>2C9>3A4>2C19). The direct glucuronidation of montelukast resulted in the formation of montelukast acyl-β-D-glucuronide and of a new metabolite (Mglucuronide) not reported previously and was exclusively catalyzed by isoform UGT1A3. In conclusion, the in vitro data suggest that the applicability of montelukast as a probe of CYP2C8 activity in vitro and in vivo may be severely compromised due to important role of UGT1A3 and involvement of multiple CYPs in its metabolism. In addition, considering the lack of selective markers for UGT1A3, montelukast may be used as a selective marker of the UGT1A3 in vitro and in vivo.

    The present paper researches the exclusive inclusion occurring in the Public High School. The goal of this work is to analyze the exclusive inclusion processes which occur in the State Public High School of Minas Gerais, its policies and acting before the exclusion, as well as analyze the factor that contributes to the students’ failure and school evasion of a state school in Poços de Caldas (MG). The field research was made through interviewing school managers, teachers and students using a questionnaire. The analyzes of the interviews showed in general, that the students are guilty of failing or evading the High School, by taking for granted the free instruction given by the State. There is a little awareness that the State only provides the free instruction, but it does not guarantee the staying of the young in school. The results of the questionnaires showed that there are other social restrictions such as the need of work to help the family, a lack of family support, precocious pregnancy, among others that also contribute to this failure and evasion. Therefore it is clear that the failures and evasions are not connected only to the school, but also to the families, to the government policies, and the student itself. We consider that the school must go beyond the role as a simple knowledge and reproductive transmitter, to be a knowledge production establishment, so being strengthened by knowledge and criticality, it may break free from the shackles of neoliberal system.

    This study approaches the “entrepreneurial education” under a critical perspective, which assesses its ideological and contradictory character. Particularly, it analyses the insertion of the entrepreneurship discussion in the courses addressed to the education of technician in administration of the Federal Institute of Education, Science and Technology of Espirito Santo, focusing on the meanings assigned by its students and teachers to a education for Entrepreneurship. The primary and secondary data were collected through research techniques of bibliographical survey, documentary research, interviews, applications of questionnaires and also formation of focal groups were described and discussed both from the point of view of statistical analysis and the theoretical references that determined the study. Authors considered reference in their areas were studied in order to meet the speech in favor of education with focus on Entrepreneurship and, on the other hand, it was adopted the thought of philosopher and political scientist Antonio Gramsci to discuss and analyze critically the theme. It is supported that entrepreneurship is superposed to work, as educational principle, in the coursers addressed to the education of technician in administration of IFES and that although the speech of entrepreneurship have been absorbed in the level of common sense by the students and teachers of these courses, this audience has developed, although embryonic and diffuse form, a germ of good sense in relation to the theme. It is understandable that the position of IFES naturalizes the school duality and reinforces the policy of students early professionalization, which distances, therefore, of the search for a universal and omnipresent project of human formation. Is defended in this study that the education policies of the federal schools, within the high school, incorporate a proposal of a Unitary Education in accordance with gramscian patterns.

    This paper describes an integrated process for recovering aluminum, iron, titanium, sodium and silica from red mud through a hydrometallurgical treatment sequence. The disposal of red mud, which is the largest waste produced by the aluminum industry, causes considerable environmental problems, and impacts costs greatly. This work presents a proposal to deal with it. Firstly, red mud is subjected to calcination at the 500-600°C range (thermal activation) so as to modify the structure of the metals present in red mud and make the attack with sulfuric acid easier. Next, the red mud is mixed with sulfuric acid and calcinated at 250- 300 °C (acid calcination). After digestion, the metal sulfates in the cake are dissolved by leaching with water and separated from the silica by filtration . Two routes to recuperate the leached metals are presented here, and the second one is analyzed economically. In this second method, silica is separated by filtration and all other metals in the leached solution are precipitated through a hydrometallurgical process in the form of their oxides. The remaining products present high purity level, thus being more easily marketed.

    This work analyzes the established funding policy in co-management agreement between the Municipal Health Sector Campinas and the Health Service Dr. Cândido Ferreira (Serviço de Saúde Dr. Cândido Ferreira–SSCF) since 1990. From the professionals‘ speech who works in this institution, I describe how, in the SSCF, making politics is inherent to the clinical practice, the negotiating relationship with that Health Sector, the writing strategies and manufacturing agreement documents. The ethnography was held at the Agreement Monitoring Commission, at the House Commission, at the meeting of the Therapeutic Residential Services‘ Team (Serviço Residencial Terapêutico–SRT) and at one training course of this professionals in this area and at commemorative event of the 20 years of its implementation. The changes arising from the reform process within the psychiatric model, described was based on mnemonic professional‘s speech, and its effects on the life of one resident of SRT, reveals the technical and architectural rearrangements that produced the rehabilitation of the inmates, the Individual Therapeutic Project and to a support network. In SRT, a ―care technology‖ was implemented, drawn from the singularity of users, combining not only psychiatric procedures and knowledge, but also clinical, psychological and geriatric in monitoring interventions (continuous control), monitoring (monitoring the distance) and management in order to govern the conduct and the life project of those. The ―clinic of detail‖, the ―therapeutic management‖ and the ―co-management relationship‖ allows the team to evaluate, calculate and discuss the individual demand, rationalized in data which are recorded in documents and made into parameters that disseminate information between professionals enabling the latter to measure the effectiveness of therapeutic interventions and improve them, plan them and manage the SRT goals. This way of proceeding, that transmutes the information in singular knowledge that subscribe thus into documents and makes them visible to the municipal administrators, justifies funding and authorizes the government practices to the SRT.

    The Jatropha (Jatropha curcas L.), which belongs to the the family of Euphorbia is a plant genetically close to the Castor Plant (Ricinus communis l.), coming from Central America and being currently distributed in all tropical regions of the globe. In Brazil, this crop has received special attention as an alternative for the supply of vegetable oil as a raw material for biodiesel manufacturing, due to the biotechnological potential of its seeds. Several studies aimed at climatic adaptations and productivity have been developed on genetic variability of J. curcas; but few studies have been developed focusing on the analysis of the microbial community associated with this species. The interior of the plant is inhabited by endophyte microorganisms, which can be isolated from disinfected surface and do not put on risk the plant tissues of the host plant. This group of microorganisms has the ability to stimulate the growth of plants by direct mechanisms, such as/biological fixation of nitrogen, solubilization of inorganic phosphate indole acetic acid production (AIA) and indirect mechanisms, such as the antagonism towards phytopathogens. Moreover, endophytic microorganisms are considered promising for bioprospecting of enzymes. The aim of this study was to perform the characterization of seventy-two endophytic bacteria associated with the J. curcas plants, with potential for promoting plant growth and enzyme production. Of this total of tested isolates 40% showed positive results for fixation of atmospheric nitrogen, 43% solubilized inorganic phosphate, 69% have produced AIA, 36% showed some antagonistic activity to phytopathogenic fungi Alternaria alternata, 12% for Ceratocystis paradoxa, 22% for Fusarium proliferatum and 23% for Fusarium verticillioides. Regarding enzymatic activity, 16% of the isolates evaluated showed amyloid activity, 29% endoglycolytic, 29% lipolytic, 20% esterase, 46% pectinolytic (18% poligalacturonase and 43% pectato lyase) 37% proteolytic. From a collection of seventy two bacterial isolates, twenty-five were identified by means of the partial 16S rDNA gene embracing seven different genres: Bacillus, Citrobacter, Curtobacterium, Enterococcus, Microbacterium, Promicromonosporaceae and Sanguibacter were isolated as endophytic bacteria of Jatropha.

    In the current globalized world, the market is characterized by the high competitiveness, easy access to information and high consumer demand. The analysis of the impacts of lean office application to the supply unit on a construction company is very relevant, considering that companies focused on the civil construction area depend for consolidation of their businesses, efficient management strategies and suppliers of materials and services, external to their organization. The use of lean office as a management tool in the purchasing department of construction companies offers a competitive advantage amid the current market situation. Thereby, this study seeks to clearly conceptualize the lean philosophy and its tools as well as the management of the information systems and also the management of the supply chain, among other aspects. One construction company was then selected for the design research. This company contributes with information for the accomplishment of this work. The method used in this dissertation consists in describing the company, drawing the preliminary map of the supply unit, from this, it was possible to draw up the value stream map in the present state. With this map it could be analyzed and proposing improvements in the production process and then, designed a value stream map in the future state, applying these enhancements. The results led to the identification of flaws and possible opportunities for management improvements in the company.

    Iron (Fe) is an essential micronutrient for cellular homeostasis. Structural component of proteins or enzyme cofactor, Fe has participation in important metabolic pathways that include oxidative metabolism, oxygen transport, cell proliferation and immune system function. Despite of its essentiality, Fe has a toxic potential to cells when in excess. So, a sophisticated system is needed to coordinate the process of absorption, recycling, use and storage. Mutations in genes related to homeostasis of this mineral may potentially alter the cellular distribution and storage. Furthermore, the Fe levels affect biological pathways such as carbohydrate and lipid metabolism. Iron content in cattle muscle has been associated with many sensory and technological parameters of meat quality. However, to date, studies that evaluate how the iron levels in the muscle can alter gene expression and the consequences for the metabolism in cattle are still absent. Therefore, this study aims to identify differentially expressed genes, metabolic pathways, gene interactions and potential regulatory biological mechanisms of physiological processes related to meat quality parameters. Longissimus dorsi (LD) muscle were collected at slaughter for total RNA extraction and determination of CFe by optical emission spectrometry (ICP OES). Eight Nelore steers, who are representatives of extreme value for Genetic Genomic Estimate (GEBV) for iron content (CFe), were selected from a reference population of 373 animals. The sequencing of the total mRNA of extreme animals was carried out from the next generation Illumina technology, which resulted in average l9.13 million of reads per sample after quality control and trimming. Data analysis carried out by Tuxedo Suite pipeline identified 49 annotated and differentially expressed genes (DE) (FDR <0.05) between groups of extremes for GEBV value for CFe. From the DE genes, 18 genes were up-regulated and 31 down-regulated for animals of low GEBV for CFe. Candidate genes for meat quality traits were identified in this study and they are related to transport and lipid metabolism. Other pathways identified through functional enrichment analysis include cell growth and development, function of the hematological system, among others. Canonical signaling pathways (interferon signaling, thyroid receptor activation (TR/RXR) and complement system) and canonical metabolic pathways (biosynthesis of stearate, fatty acid biosynthesis and palmitate biosynthesis) were also identified. Although this study did not identify genes with direct role in the regulation of Fe content, our results suggest biological pathways influenced by this mineral and contribute with information to the understanding of their participation in processes affecting quality of meat. This information will be useful in developing strategies that contribute to the production of better quality meat, healthy and nutritionally rich. In addition, this information may help in understanding of metabolic disorders in other species, including humans.

    This paper presents the results of the economic feasibility analysis of implementing a distributed generation system based on electricity produced from wind and / or solar systems in the cities of Sorocaba, São Paulo; Brasilia, Federal District; Rio Branco, Acre; Porto Alegre, Rio Grande do Sul; Manaus, Amazonas and Fortaleza, Ceará. Thus, three scenarios were raised as well as the consumption of energy generated, in full or having to be complemented with the use of the normal distribution network. For each of the scenarios considered the following indicators were raised: NPV, IRR, and Payback final balance in the life of the equipment, based on a TMA equal to the government Selic rate. As a result we had a payback between 8 and 12 years in the best case scenario and between 12 and 16 years in the worst scenario analyzed, but all were positive NPV and final balance at the end of life of equipamrnto In this way it was possible to determine for these cities that the best structure to be implemented and serve as a basis for analyzing the implementation of this same infrastructure in other locations in Brazil, particularly in more remote places where access to electrification in the centralized system becomes more difficult to arrival.

    ERPs are complex systems that handle large amounts of data and links among this data providing to its users different information. Usually, developers of this type of application dedicate their efforts to guarantee correctness of the functionality and information consistency; so usability issues become secondary. It is widely recognized that ERP systems own complex interfaces that negatively affect the ability to use these systems. However, it is observed that certain rules that assist to improve interfaces may be automated, thus it is possible to create automated processes to help the development of such applications. This work presents a model driven approach for retail ERP systems with functional usability features (functional features with high impact on usability), called FUF. This study consisted in two stages. In the first one was made literature and market research of retail ERP systems. The second step was the development of a metamodel for retail ERP systems with functional usability features, called MetaUsaERPWeb, it was also carried out the development of a M2C transformer for MetaUsaERPWeb with PHP target platform. Finally, in the last step, the validation of the proposal was made in a case study, with two tests: the first conducted an experimental study to validate the proposed approach against the traditional approach. The results showed that the groups using MetaUsaERPWeb were more efficient, produce more lines of code and better applications. The second analysis compared the applications developed from the traditional approach and the use of MetaUsaERPWeb (first analysis); the results showed that applications built with MetaUsaERPWeb violated least usability heuristics in 60 % of cases.

    The estimated housing deficit in Brazil was 5.6 million in 2008, in which 83.5% was in urban areas, wherein to meet such demand there is a need for industrialized construction. Prefabricated building systems with precast panels for residential buildings were largely applied in Europe after the Second World War and it has been applied recently in countries of Latin America and Asia. Although construction companies have been using building systems with precast panels for affordable housing in Brazil since the 80´s, the absence of a prescriptive code of practice for design of precast panels demands certification for each system, which needs to meet the performance requirements according to ABNT-NBR 15575:2013. In order to increase the application of prefabricated systems a new Brazilian Code of Practice for Precast Panels, based on international codes, has been concluded and it is now waiting for final approval. In order to achieve optimum performance, constructability and sustainability of the building project there is a need for integration between architectural and structural designs, as well the interaction between product and production, starting from product development based on the analysis of added value for each project until the rationalization of the processes. The level of prefabrication depends on the number and repetition of units. The aim of this research is to identify and define design guidelines based on performance for building systems with precast concrete panels for residential buildings. The literature revision was carried out starting from international references and codes until the study of the Brazilian codes of practice, including the new code for precast concrete panels. In addition, the research presents the main types of panels and typologies for residential buildings with potential to be applied in Brazil. Finally, an example of performance based design for precast concrete panels is presented with some discussions. This study demonstrate that architects and structural engineers can now design building systems with precast panels based on the new codes of practice and numeric simulations without the need of further tests for certification.

    The genus Salmonella spp. has been extensively investigated because these bacteria are important pathogens that frequently cause severe diseases and gastrointestinal infections in humans and animals. Moreover, in recent years, Salmonella has called attention due to the excellent results in the production and in vivo delivery of various substances with potential application in Vaccinology. However, there is still little information available concerning aspects of its metabolism, which hampers both the development of new attenuated strains and the large-scale production of live cells and cellular components. Thus, this work aimed to study the S. typhimurium LT2 metabolism, using traditional and innovative approaches to investigate different carbon sources as well as different bioreactor operation modes and aeration conditions (aerobic and anaerobic). Results obtained in batch and chemostat cultivations indicated that S. typhimurium metabolism differs significantly from E. coli metabolism, closely related bacteria species with regard to the central carbon metabolism. The main difference observed between these bacteria was the high level of acetate production exhibited by S. typhimurium LT2 cells, which, differently from E. coli, occurred even at the lowest dilution rate evaluated. Currently, genome scale metabolic models are important tools for better understanding the phenotypic behavior of many organisms. Therefore the model STM_v1.0 reconstructed for S. typhimurium LT2 was evaluated, comparing experimental data, obtained in chemostat cultivations, with model predictions. Since this model was derived from E. coli model, the simulated results for biomass formation were overestimated and, consequently, predicted acetate fluxes were lower than those obtained experimentally. Therefore, to obtain experimental data useful to improve the model and to reach a better comprehension of S. typhimurium metabolism, the technique of metabolic flux analysis using isotopic labeled substrate was adopted, allowing determination of the fluxes for the main pathways of central carbon metabolism of Salmonella. This analysis revealed different preferred metabolic pathways depending on the specific growth rate. At the lowest dilution rate evaluated, D = 0.24 h-1, glucose was catabolized predominantly by the pentose phosphate and glycolysis pathways, while at the dilution rate of 0.48 h-1, the major pathway of glucose oxidation was Entner-Doudoroff. In addition, a relatively high flux through the citric acid cycle at the higher dilution rate studied was observed.

    The black pepper is the most important spice commercialized globally, with Brazil being one of the main producers in the world. Yet few studies to optimize the production of this commodity process have been found in the literature. The objective of this work was to study the drying the black pepper grains. The physicochemical characterization of the material with varying humidity, measuring linear dimensions (mean Sauter diameter, minimum, average and maximum diameter, and perimeter) was performed, as well as surface area, volume, sphericity, and also the bulk density, real and bulk, porosity and grain. Drying experiments were conducted in a hothouse at different temperatures. Assays were carried out a fixed-bed dryer for determination of the thin layer. Drying kinetics experiments were performed on a thin layer in a dryer with forced convection temperature ranging from 50 to 70 °C, and air velocity of 1.0, 2.0 and 4.0 m/s. With these data, there have been adjustments of Lewis, Page and Overhults equations, and the Forward model with simplifying assumptions for the diffusivity. The results obtained show that the diffusive model was the most suitable. It also promoted the essential oil extraction of the grains and the results are consistent with the literature.

    The development of Libras teaching-learning conditions for distance education is necessary in the Universidade Federal de São Carlos (Ufscar) and other higher education institutions. It is pivotal discussing the topic since there are few researches about it. This study presents the researches and analyses of Libras teaching-learning aspects as a second language in distance education by Learning Management System (LMS) and via Moodle. To that end, the research considered the environment suitableness and the communication and interaction processes between the LMS agents (students, tutors and professors). A mixed method (qualitative and quantitative) was applied to on-line questionnaires regarding the Libras I course from the Education and Musical Education departments in UAB-Ufscar. Further, the agents’ opinions and perceptions concerning the tools, the pedagogical procedures and the learning/teaching interaction were analyzed. The analysis was based on Bakhtin’s theoretical assumptions regarding the fundamental dialogical interactions in the language teaching-learning process, which was applied to Libras in this study. The subjects surveyed were 103 students (whose data were clustered in Study 1); 9 virtual tutors (whose data were clustered in Study 2) and 3 professors (whose data were clustered in Study 3). A protocol was set up to analyze this data and according to it, for Study 1, the data was organized and split in the following categories: a) Tools; b) Pedagogical procedures; c) Learning aspects. For Study 2: a) Virtual tutoring experiences; b) LMS tools; c) Interaction and learning. For Study 3: a) Virtual teaching experiences; b) Distance interaction with students. The opinions and perceptions regarding different items got good ratings by the LMS agents and the course, in general, seems to have reached its goals. The researchers analyzed the propositions shown by the agents and they indicate an enhancement of Libra courses in order to make them more accessible to hearing students.

    The budget, proper planning and control play a vital role in getting profit in the current scenario in the construction sector, and the Building Information Modeling (BIM) can be a key factor in the success of businesses. This work aims to analyze the main impact of technology BIM about the planning, budgeting and control, as well as present a schematic representation of the impact of BIM on the flow of the processes studied. The methodology used in the research was the field of study, basically divided into three stages: preliminary exploration, data collection and impact on flows. Through a proposal schematisation of the flow of the processes studied, it was possible to propose details of the information exchange requirements, as well as the intensity of the impact of BIM use in each activity. In this context, it was found that the BIM platform has moderate impact in the budget, planning and control.

    The monoaromatic hydrocarbons composed by benzene, toluene, ethylbenzene and xylenes isomers (BTEX), are commonly found near local oil refineries, filling stations, or around pipelines, as a result ofleaks and/or spills. In such places, a microbial activity not only promotes the transformation of these compounds into products such as CO2 or methane, but also convert them into highly toxic and/or carcinogenic compounds. Some of the metabolites resulting from biotransformation process are benzylsuccinic acid, 2-methylbenzylsuccinic acid, isomers of toluic acid and benzoic acid. The aim of this study is to increase knowledge about the biodegradation of monoaromatic hydrocarbons in soils, by investigating their removal under three different conditions, and to evaluate the formation products associated with their degradation. This work was carried out with series of anaerobic microcosms with three different electron acceptors acting as oxidants: sulfate, nitrate and iron (III). The individual effect of each in a soil contaminated with BTEX and another set containing a mixture of these electron acceptors with soil contaminated with conventional diesel were investigated. The concentrations of BTEX and metabolites were monitored for 90 days. Previously, it was necessary to develop suitable analytical methods for monitoring BTEX through gas chromatography coupled with flame ionization detection (GC/FID) while high-performance liquid chromatography coupled to a mass spectrometer (LC-MS/MS) was used for determining the metabolites. A preliminary microbiological characterization of groups of bacteria was carried out, showing a prevalence of nitrate-reducing bacteria in the soil utilized. Evidence that the BTEX compounds may be removed in anaerobic conditions linked to nitrate and sulfate reduction were found. Using iron (III) like electron receptor was not observed a significant decrease in the concentration of contaminants during the three months of incubation, except for toluene. Results also show that toluene was the compound quite easily degraded in anaerobic conditions in soil, enriched with different electron acceptors. On the other hand the appearance of metabolites was quickly detected in the series of experiments employing nitrate, due to the higher content of native nitrate reducing bacteria in the soil, associated with the fact that nitrate has a higher oxidizing power from the electron receptors studied. In case of iron (III), metabolites were slow to appear, however higher concentrations were detected mainly of benzylsuccinic acid from toluene degradation. To establish a scenario more realistic of contamination, a soil was artificially contaminated with diesel. However, due to the large number of compounds present in the fuel, the toxicity of the medium was increased, causing inhibition of the biological activity and thus affecting the efficiency of BTEX removal.
