There are several issues related to the pedagogical use of technologies for the construction of knowledge in the current Brazilian education system. Some pass through large and complex issues, such as the transmission of trend change instruction conducted through blackboard and chalk for a reality involving the use of digital technologies as mediators of this process. In this scenario, the future teacher lacks experience in their formative process, the pedagogical use of technology to be able to incorporate them into their lessons. There are several challenges to this incorporation into the teaching-learning process, since simple computerization of school environment does not guarantee the desired benefits. This study assumes that the pedagogical use of Information and Communication Technologies (ICT) contributes enhancing, facilitating and encouraging the teaching of Mathematics and should be part of initial and continuing teacher training. So this research has the main objective to analyze, from the point of view of the participants in a formative experience, contributions and limits the insertion of the pedagogical use of technology in teacher training so that they can reflect on and use them as a teaching tool in Basic Education in their future professional activities. The theoretical framework for this teacher training focuses on the use of technology in the initial training of teachers of Mathematics and the pedagogical use of ICT. More specifically, it assumes the Lee Shulman knowledge bases and the TPACK framework (Technological Pedagogical Content Knowledge and Technological Knowledge and Pedagogical Content) Koehler and Mishra. Data were produced by 12 undergraduate students who attended a formative experience over the past year students for a Degree in Mathematics. In this experience they had the opportunity to select digital tools and teach specific classes in detail planned for the computer lab. In a later stage, a couple of interns pedagogically used GeoGebra software for teaching quadratic functions for two 1st year of high school classes. Data were obtained through the application of a pool to characterize the subjects and daily researcher and diaries of the participants followed for the practical classes were prepared, as well as interviews from semi-structured pool. The qualitative analysis was organized in a way that links aspects of learning and difficulties that participants had regarding the selection of technologies and their use in simulated classes or basic education, in the computer lab during the supervised training. The results show learnings, indicate potential and limits on the use of technologies and also emphasize the need for experience of undergraduate students in the pedagogical use of ICT so that they feel at ease in using them pedagogically throughout their careers.

In the agri-chain of cassava starch in Brazil, the supply of firms is through different governance structures. These structures range from the purchase via the spot market - without any contractual control over the production - to the hierarchy or vertical integration, structure in which the company is growing in own areas, with full control over the production. Between these two extremes were also identified other governance structures, which are called Hybrid arrangements that can approach the spot market or hierarchy. This essay aimed to identify the factors that influence the decisions of the paranaenses starch factories on the governance structures in buying - cassava supply in the state of Paraná. The specific objectives are: a) show if there is specifics that support the necessity to search for a particular organizational arrangement to the detriment of business through the spot market in the state of Paraná; b) analyze the factors that justify the choices of cassava starch factories for plural or singular forms in the state of Paraná; c) comparing the efficiency of the use or the combination of governance mechanisms in cassava starch factories in Paraná State, considering idleness as an index for the year 2014. The entire analysis of this essay is based on the theoretical assumptions of the New Institutional Economics (NIE), especially in the Transaction Cost Economics (TCE). In this essay the explanatory method was the most appropriate, once for this it sought to identify the determining factors for the occurrence of the phenomena observed: i) coexistence of plural forms of governance to coordinate the purchase of cassava by starch factories in Brazil and in the state of Paraná. This research method more approach the scientific knowledge to the real world as it explains the reason and why the facts. In the case of cassava, the characteristics of transactions - temporal and locational characteristics, as well as uncertainty and frequency – were not relevant for the choice of governance structures, on the contrary to what literature indicates. Even considering these characteristics, in Brazil and in the state of Paraná was prevailing the coordination by the spot market. The results also indicated the existence of a plurality of transactions in many levels - with different agents, and similar agents in a single transaction - since the combination of different governance structures can reduce transaction costs and even increase the efficiency of industry here measured by the reduction of industrial idleness.

For any action in fauna’s conservation it is necessary to have the previous knowledge of the species in order to adopt the best intervention strategies and to optimize the process. This way, even though the Southern Brown Howler monkey is considered vulnerable to extinction in Sao Paulo State, by the Environment Ministry, few studies on these animals have been conducted at the Fontes do Ipiranga State Park - PEFI, Atlantic Forest urban fragment in the city of Sao Paulo. Therefore, this study is aimed to get basic information about the ecology of the two groups that inhabit the region, as home range, activity pattern and diet, create data in the role they play in the maintenance and regeneration of the forest, as the seed dispersers and to analyze the effects on germination in seeds that passes through their digestive tract. The groups were followed in the period of November 2013 to October 2014, the group in the Zoological Park Foundation of São Paulo (area 1), with the final number of five individuals, and the group in the Botanical Garden of São Paulo (area 2), with final composition of nine individuals, both located in the protected area Fontes do Ipiranga State Park - PEFI. The areas belong to different zoning in the management plan of the protected area, and have different degrees of conservation of its forest. Each group was monitored monthly for three full days. Diet items were recorded by the ad libitum method and subsequently identified, totaling 55 species. Syagrus romanzoffiana highlighted by the large participation in the diet of both groups. The seed germination tests comparing a control group (seeds that have not passed through the digestive tract) with samples taken from animal feces showed a significant positive effect on Ficus luschnathiana and Cecropia spp. seeds. The home range was determined by the method of the Minimum Convex Polygons with points being marked in the GPS every half hour, and found home range of 3.5 ha and 5.6 ha for the area’s groups 1 and 2, respectively. The activity pattern was made by the scan sampling method, with scanning every ten minutes and resulted in the usual pattern described for the species: high percentages of time spent resting and low social interaction.

The present research is guided in discourse analysis "about" and "the" practice of security officers at "Cracolândia" (or Crackland) - located in the central region of São Paulo. The main purpose is to identify the differentiation between users and drug dealers by the officers. The empirical view focuses the Municipal Program to Combat Crack and Other Drugs, entitled "Open Arms", which foresees the intersectorality between the work of Social Welfare, Health and Public Safety in the "fight" to crack. I discuss my object from the speeches of security officers, social workers, health workers and crack users on how policing will be in the region as well as on how it is performed in practice. Documental and field research was performed with different agents that act on the management and use of crack users in the region of "Cracolândia". From the field data, it was possible to note the production of a criminal selectivity in how to operationalize the distinction between users and dealers, question to which I would like to give attention. Thus, I try to fill a gap in the studies of public policies to combat the drug in relation to the apparatus of control exercised by state agents of public security in the region of "Cracolândia".

Continuous flow technology of cycloheptanic compounds derived from (R)-(–)-carvone and the C23-C31 fragment used in the total synthesis of spirangien A methyl ester and spirodienal A polyketides” In the first part of this thesis is described the improvement and development of two synthetic routes to the cycloheptenone 73, in the deca-gram scale, from the monoterpene (R)-(–)-carvone (58). Were developed reactions in the continuous flow mode to accelerate and increase the scale production of 73, and thus avoiding chemical logistics issues. Sharing the principle of the diversity oriented synthesis and taking advantage from the cycloheptanic chiron flexibility, were developed α-carbonyl alkylations followed by catalysis with transition metal, to get, in a fast way, structurally diverse compounds such as spiro 74, guaiane type 75, xathane 76 and the tris-ketal compound 78. The second part of this thesis encompasses some results of our collaboration with Prof. Steven V. Ley CBE FRS and deals with the synthesis acceleration of the fragment 145 through the usage of continuous flow processes. The compound 145 is an advanced synthetic intermediate for the spirangien A (79), spirangien A methyl ester (80) and spirodienal A (81) syntheses, which are on matter at the Prof. Ley`s group. xxiii

The aim of this study is to analyze how professionalism, difference, gender and generation in the journalism career are articulated, from the exam of the journalists’ discourses in the city of São Paulo. We use up the concept of professionalism and the Sociology of the Professions theoretical reference, based on the contributions of Eliot Freidson and Julia Evetts to understand the values of journalism, the representations around what it would be the journalist’s function, the meaning of the changes in the profession, with the emergency of a new journalist’s profile, the relations of the profession with the learning at the universities and at the editorial rooms, the historical changes according to the orientation of the journal and the professional, and their specificities with reference to the process of professionalization of the journalism in Brazil. Our aim is to comprehend how female journalists are represented in different discourses of difference. For this, our approach is set on the Avtar Brah’s theoretical assumptions, highlighting the concept of difference as an analytical category and its several meanings. We have also based our analysis on other cultural studies agents that discuss about the decentralization of the subject and its identity, as the internal diversity that characterizes gender. Fifteen journalists were interviewed, women and men, who live and work in the city of São Paulo, of different generations who act in different types of media and with different types of hire in their relations of work. The selection of the interviewed women searched, contemplate single women professionals, married, with or without children, with different time of work, that represent the time dedicated to the personal and professional lives, corresponding to the impact of personal life in the construction of the career and to the possibilities to balance between these two dimensions in the social life.

The Brazilian industry has become in recent decades, which created an intense debate about a possible process of deindustrialization faced by the Brazilian economy. Some authors believe that the country has faced a process of deindustrialization, while others argue that this is just a period of adjustment faced by the economy, which does not characterize this fact. The fall of the Manufacturing Industry's participation in the Gross Domestic Product of the country, coupled with the increase in exports of commodities by Brazil are among the main factors that lead to believe that the country has lost links in the production chain and specializing in goods with little degree of differentiation. In this context, this paper aims to analyze the main data of the Brazilian industry to identify the process of deindustrialization pointed in Brazil. We wanted to understand what the main lines of argument in the debate on the subject, and understand how they behaved the main economic aggregates of the country and other economies in the world, producing a structural analysis on the subject.

The inhibition of the acetylcholinesterase (AChE) might be an excellent therapy in controlling Alzheimer’s disease as stated by the cholinergic hypothesis. In this context, the inhibitors of AChE, are of medical and commercial paramount interest as therapeutics for Alzheimer’s disease and as pesticides. However, the conformational changes in inhibitors with AChE complex facilitate the rational design of some novel inhibitors with increased potency and specificity. Therefore, solution state NMR is a novel approach that seems to fulfil almost all conditions necessary to investigate the AChE-inhibitor complex. In this perspective, a combined strategy of STD, Tr-NOESY, DOSY, and docking simulations were applied to compare the bindings of four synthetic coumarin derivatives to tacrine for their binding potentials. Intriguingly, one of them (compound 1) was found to have not only the stronger affinity than the control but could bind with three sites. Furthermore, a competition of three inhibitors (gallic acid, 4- methylumbelliferone, and scopoletin) was performed by taking help of the STD NMR experiments. Interestingly, none of them was competing for the some particular binding site. Nevertheless, in titration studies gallic acid was found best based on dissociation constant values. Moreover, an ethyl acetate fraction and its water suspension of the Terminalia Chebula RETZ, fruit extract was studied. Three compounds (4-hydroxycinnamic acid, Ethyl-4-hydroxycinnamate and lupeol) were seen to involve in interaction that were later recognized by 2D NMR and ESI mass techniques. Moreover, for the first time in the Federal University of São Carlos, these NMR methods for the determination of the bound conformation of any inhibitors towards AChE using NMR spectroscopy have been applied.

The objective of this thesis is to analyze the Integrated Education, generic name of Professional and Technical Education in middle level combined with a secondary school in integrated mode, under the Law of Directives and Bases of National Education (LDB 9.394/1996) updated through Decree 5.154/2004. We sought to understand what is the integrated education: definition, characteristics, social and political purposes, theoretical-methodological referential and pedagogic-didactic fundamentals. The methodological proceedings was marked: on one hand, by theoretical analysis of the education and of the socialist pedagogy in the thought of Karl Marx, Vladimir Lenin, Nadezhda Krupskaya, Anatoli Lunacharsky and Antonio Gramsci, specifically on the concepts of technology education, polytechnic education and unitary school. On the other by a theoretical and documentary analysis of the legislation, other official documents and literature on the national education and the recent reforms of education, secondary school and integrated education. The study concluded that in the meanders of the integrated education this underlying a broader process of expanding the spirit of professionalization to practically all the Brazilian education system, especially for secondary school. The reform of secondary school, it happened in parallel and conditioned a professionalizing reform.

The replacement of chemical products by renewable raw materials is an important factor for the emission control of CO2. Consequently, there is a great commercial interest in the conversion of ethanol into 1,3-butadiene. The 1,3-butadiene compound is used in the production of a variety of synthetic rubbers and one important example is butadiene-styrene rubber (SBR), which is used in the production of car tires. This work studied the modification of the acid-base properties of MgO/SiO2 bifunctional catalysts and the understanding of different methodologies used in the preparation of these materials for the conversion reaction of ethanol into 1,3-butadiene. MgO/SiO2 catalysts of varying amounts of magnesia/silica were prepared by four different methods: i) precipitation followed by the mixing of the oxides in a ball mill, ii) precipitation of MgO followed by its mixing with aerosil silica in a ball mill, iii) precipitation of MgO followed by the mechanical mixing of the oxides and iv) sol-gel. The catalysts were characterized by X-ray diffraction, CO2 Temperature Programmed Desorption, Scanning Electron Microscopy and Specific Surface Area. Catalytic tests showed that the highest selectivities for 1,3 -butadiene were observed for the (MgO/SiO2) coprecipitation method and oxides mixed in a ball mill. The TPD-CO2 results demonstrate the formation of basic sites with the addition of SiO2 to MgO and the density of basic sites presents a great variation in the ratio MgO: SiO2. The catalyst MgO/SiO2 (5:1) was the most active and selective for 1,3-butadiene. The addition of CaO or SrO these catalysts have not resulted in increased selectivity for the formation of butadiene, but observed an increase in the acid properties, possibly due to non-inclusion of these oxides in MgO lattice and later the formation of basic sites of the type MgO-Mg-O-Si.

Bees are social insects of fundamental importance to the environment, because they are responsible for pollinating more than 70% of existing agricultural crops in the world. Brazil is the country with the highest number of described species, with representatives of most families. Among representatives of the Apidae family, is the Melipona scutellaris specie, commonly known as "uruçu" or "uruçu do Nordeste”, it is easy to handling and very well adapted to the climate of the state of São Paulo. However, due to the intensive use of pesticides, native bees are suffering the consequences, because, although they are not the target of insecticides, are highly vulnerable to contamination. Among the insecticides developed in the 90s, the neonicotinoids and fipronil have been identified as the main substances involved in collapse, and were suspended in 2013 in the European Union for two years for best evaluation. These insecticides are often used simultaneously, so bees can be contaminated with both molecules. Due to this fact, the aim of this study was determine the median lethal time (LT50) of fipronil and imidacloprid insecticides separately and synergistically on forage bees of M. scutellaris. For this, was obtained only the LD50 and LC50 of imidacloprid, according to the rules of the OECD, because values of fipronil were established by Lourenço et al. (2012a, 2012b). The LD50 of imidacloprid obtained was 2.41 ng a.i. / bee (24 hours) and 1.29 ng a.i./ bee (48 hours). The LC50 value found was 2.01 ng a.i./μL diet (24 hours) and 0.81 ng a.i./μL diet (48 hours). These data indicate that M. scutellaris specie is more sensitive to the insecticide imidacloprid that A. mellifera africanized. From these values, was obtained the LT50 based on topical and oral contamination of fipronil and imidacloprid insecticides and also these substances acting together. The results showed that fipronil has LT50 greater than imidacloprid. When acted in combination to LT50 presented intermediate values between the LT50 fipronil and imidacloprid, isolated. Then, according to the values obtained, there was not synergy, but a decrease in the toxicity of imidacloprid.

This work presents the development and implementation of a didactic sequence in order to motivate and teach school students quadratic functions. To do this, we built a cannon made of tiner cans and prepared a serie of activities that have been subdivided into three phases: construction, competition and activities with the use of the software GeoGebra. The work done with students in these aroused a greater interest in the matter and was extremely valuable because students did not forget the acquired learning.

Angiotensin converting enzyme 1 (ACE1) is a dipeptidyl carboxypeptidase that converts angiotensin I (decapeptide) to a vasoconstrictor octapeptide angiotensin II. Thus, ACE presents an important role in blood pressure regulation. There are many synthetic commercially available ACE inhibitors such as captopril, lisinopril and enalapril. Due to their side effects, naturally occurring inhibitors have been prospected. In order to endorse this research field we have developed a new tool for ACE ligand screening. To this end, ACE was extracted from bovine lung, purified and chemically immobilized in modified ferrite magnetic beads (ACEMBs). The ACE-MBs have shown a Michaelian kinetic behavior towards hippurylhistidyl- leucine (HHL) and was also able to catalyze the conversion of angiotensin I to angiotensin II. Moreover, as proof of concept, the ACE-MBs was inhibited by lisinopril with an IC50 of 10 nM. At the fishing assay, ACE-MBs were able not only to fish out the reference inhibitor, but also three peptides from a pool of tryptic digested BSA. ACE-MBs emerge as new straightforward tool for ACE kinetics determination, inhibition and binder screening.

Despite the rapid tests market in Brazil being in full expansion, the country does not have a tradition of manufacturing these kits. Therefore, it is very difficult to find, in the national literature, reports to guide the development process of these kits. The lack of published reports is aggravated by the difficulty of understanding the rules and laws governing the sector and by their subjectivity. The aim of this study was to describe a methodology to develop and validate a diagnostic kit, according to prevailing regulations. For this, a self-diagnostic semiquantitative kit for detection of Luteinizing Hormone (LH), using the rapid test platform, was taken as a model and all the procedures required in each stage of the design of the product, including planning, development and validation, have been described. The kit developed complied with all established operating requirements and achieved 97.39% sensitivity and 97.92% specificity. The cross-reaction tests showed that the kit suffers interference from samples containing hCG, due to the high similarity of beta chains of the hormones. Despite this fact, the performance of the test was better than the performance of the kit available in the market today. Based on the results obtained, we conclude that the procedures presented, which comply with the management standards ISO 9001:2008 and ISO 13485:2004 and also with the Good Manufacturing Practices of the RDC 16/2013, were effective in obtaining the kit and may be used as a model for management and development of similar projects within companies operating in the diagnostic market.

The purpose of this dissertation is to relate the critical success factors to the stages of the knowledge management maturity through a empirical study. Some knowledge management maturity model were developed over the past decade, but they are incomplete, does not perform a systematic conceptual identification of the factors that should compose the model and, in most cases have a lack of empirical evidences. Consequently, there are gaps to be filled in order to develop a more complete model. Through systematic review of the literature, the critical success factors of knowledge management maturity models were compared to the critical success factors cited by knowledge management literature. The relation between these factors and the knowledge management stages were tested by empirical research. The collect data instrument was developed with assistance of knowledge management and statistics expertise’s. The Embrapa – Brazilian Enterprise for Agricultural Research was the object of this study. Embrapa is a public institution that has the aim of develops technologies, knowledge and technique and scientific information about Brazilian agriculture and livestock. The selection of the organization was guided by importance of the institution as national reference on innovation and development of new products and technology, issues deeply related to knowledge management. The data collection involved all leadership and management positions of all Decentralized Units from Embrapa, representing a population of 180 respondents from 46 organizations, with a return rate of 67,7%. The data was analyzed through descriptive statistics, linear regression techniques, Fisher’s exact test and polytomous logistic regression. As main result, among others, we could characterize the critical success factors in knowledge management stages and identify associations between these variables (critical success factors and knowledge management stages), showing, for example, that the technology and the top management support have an important role, mainly, at the second stage.

The purpose of the present research was to analyze the process of introducing a Support Nucleus Family´s Healthy (NASF) team into the cities of the state of São Paulo. Considering that the introduction of the team is one of the most important stages to the development of work processes in health, it is important to discuss this stage in a NASF context, as it is one of the main projects supporting the Health Family's Team (ESF) of the Ministry of Health. In terms of methodology it is a qualitative research, of a single case and in process. Therefore, several semistructured interviews were carried out with managers of the Municipal Secretariat of Health and focal Group members of the NASF team. The analysis by categories of topics was the technique used to explore the material collected. The research project was analyzed and had its development approved by UFSCar s Ethics Committee on Human Research and by the Municipal Secretariat of Health. The discussion indicated that the introduction of the NASF into the municipalities occurred in a very disturbed way and with few adherence to the proposals described in the NASF acquisition project. The professionals who integrated the first NASF teams were already part of the municipality health system. This choice for the selection and formation of the teams has brought negative consequences for its consolidation, once the professionals had few experience or no knowledge at all related to the work proposal. Nevertheless, although the work process between NASF and ESF has developed very slowly, due to, as related by the participants, the lack of communication and management support, the team was able to make it feasible some ways of support dictated by the Basic Attention Brochure, which sets out NASF s policies. The main tool used by the teams during this process were the case discussions. Through them, the components of the NASF team were able to work on several topics relevant to their work, such as interdisciplinary, team work and construction of care plans through the singular therapeutic project (PTS), establishing the matricial support as the principal element for their work. However, the development of the work and the introduction period have shown lack of planning, and, as a main consequence, lack of dialogue between management and NASF, making even harder the introduction process of the team in the health network. The establishment of collective places for continuous education could become a propelling spring, once, rethinking the work, looking at the problems and identifying its meanings, may lead to changes in certain contexts from the motivation of the players involved.

The operation strategy is responsible for key decisions of activities to be perform by the function of production, in order to achieve competitive advantage in the market. Therefore, studies on the operations strategy are recurring in the industrial and service sectors. Agribusiness is the primary responsible for good Brazilian economic results, mainly by export the grains produced by rural enterprises throughout the country, especially in Mato Grosso State. However, there is little research about management of farms, even less for the studies on competitive positioning and performance of these enterprises regarding operation strategy. Thus, this research aimed to identify and analyze strategic groups of grain farms established in the Mato Grosso State West Center counties regarding the operations strategy issues. Therefore, a cross-sectional survey-study was design directed to the farmers from the APROSOJA West Region. Data were collected using a structured questionnaire with questions about the farm profile, competitive priorities and structural and infrastructural decisions of producers on grain production. The responses obtained, 104 from the 1020 farms registered in the West Region, had a return rate of 10%. Data analyses were carried out using descriptive statistics and multivariate analysis methods. Descriptive analysis showed the main farm characteristics (location, size, employee number, main products, diversification, etc.), the target markets and their factors (main customers, certifications, marketing forms). These issues enables to identify the competitive strategy of the surveyed farms. Factorial analysis has provided verification of the constructs latent factors, which forms the operations strategy content - competitive priorities and structural and infrastructural decisions. These factors showed the variables that best explains the constructs to this research context and are useful as input to a third analysis, which proposed the formation of strategic groups. Using cluster analysis, strategic groups were formed from the latent factors of Operation and competitive strategy variables. Results indicate very similar competitive priorities characteristics; however, investments in structural and infrastructural decisions apparently have allowed a better performance to the farms. The main theoretical contribution of this work for operations strategy is the research of this concept in an agricultural context, where it was possible to identify latent factors components and to understand how the strategic decisions coherence for operations, also in this segment, enables positive result achievements to farm companies.

The purpose of this thesis is to contribute to the edification of knowledge concerning the construction of youth masculinity. The hypothesis is that heterosexuality needs homosexuality for its own strengthening and that by accusing, signaling and judging the "less" or non-hegemonic male, or the homosexual, it reinforces itself. Established by cultural experiences, masculinity is built through social relationships and communication in places such as school and the internet. So, to connect both of these spaces methodologically, the study initially includes 600 subjects, both male and female, of two educational institutions in the municipal of Uberaba-MG, Brazil. From this particular group only 200 males, between ages 14 to 16, were identified and invited to continue taking part in the study. The students were asked several objective questions which led to the identification of 17 out of the 200 subjects. The use of communication through social networks with the identified males allowed for the observation of their speech and expressions, which has been used as reinforcement and reference for this discussion. So referenced, conceivable understandings of social components and procedures of the formation of male adolescents’ identity and the independence between each category have risen. Furthermore this thesis attempts to contribute to the understanding of how masculinities in adolescence are determined, experienced and inherited

The pharmaceutical compounds residues, especially antibiotics, are among the most worrying emerging environmental contaminants. These residues potentially cause negative effects on microorganisms that play an important role in the ecosystems processes, dynamics and stability. The objective of this study was to evaluate the oxytetracycline (OTC) (against bacterium) and imazalil (IMZ) (against fungus) action on the aquatic macrophyte Egeria najas Planch decomposition in laboratory bioassays. Microcosm experiments were performed in borosilicate flasks, in triplicate, containing fragments of E. najas and water collected in Beija-Flor Reservoir, Jataí Ecological Station, Luiz Antônio, São Paulo, Brazil. The experiments were performed as follows: water and macrophyte; water with OTC and macrophyte; water with IMZ and macrophyte; water with a mixture of OTC and IMZ and the macrophyte. The OTC decay in water was also analyzed in microcosm without plant detritus addition. The experiments were kept in the dark, at 21 °C, in two experimental conditions: aerobic and anaerobic. Water pH and electrical conductivity of the systems were measured at the sampling times (1, 3, 5, 15, 35 and 65 days after the onset of the experiments). Dissolved organic carbon (DOC), total nitrogen (TN) and OTC were analyzed in the dissolved fraction. Bacterial diversity was evaluated by Denaturing Gradient Gel Electrophoresis (DGGE) and bacterial cell number counted by epifluorescence microscopy in the aqueous portion. A first-order kinetic model was adopted to describe and compare macrophyte decomposition at different treatments. The results showed that the refractory fraction decomposition and the DOC mineralization were lower in experiments containing antimicrobial OTC than in control experiments in aerobic conditions. Changes in decomposition rates were not observed in anaerobic conditions. The OTC action was not effective due to its adsorption to particulate plant material (between 61 and 65%). According to the DGGE profiles obtained for the Bacteria Domain, the bacterial community in bioassays has been modified throughout the experiment time and according to the treatment. From these results, it was concluded that antimicrobial agents can alter the rate of decomposition of detrital plant material in water, depending on environmental conditions.
