Análise do efeito das condições operacionais e características geométricas do leito de jorro na secagem de pastas
(Universidade Federal de São Carlos, 2015-07-06)
In this present work, the fluidynamic and drying process of paste in a spouted
bed was analyzed. The experiments were conducted using polyethylene particles of 4.38 mm
of diameter and 930.5 ± 0.3 kg/m3 of specific mass ...
Influência dos íons metálicos na atividade e estabilidade de (hemi)celulases e no processo de sacarificação da biomassa
(Universidade Federal de São Carlos, 2015-02-26)
The enzymes involved in the conversion process of lignocellulosic biomass into second generation (2G) ethanol add a high cost to the process. Studies reported in the literature indicate that some metal ions, easily found ...
Aspectos morfológicos, reológicos e fisiológicos dos cultivos de Escherichia coli recombinante
(Universidade Federal de São Carlos, 2015-04-30)
The use of Escherichia coli cultures to obtain heterologous proteins poses as a successful application of biotechnology for the production of drugs and enzymes. However, the stress caused by the synthesis of the recombinant ...
Estratégias de melhoria do bioprocesso de produção de enzimas celulolíticas por Aspergillus niger a partir de bagaço de cana-de-açúcar para a produção de etanol de segunda geração
(Universidade Federal de São Carlos, 2015-03-05)
The second generation ethanol (2G) production from sugarcane bagasse is a promising
strategy to increase ethanol production per hectare. The 2G ethanol production comprises the steps of biomass pretreatment, hydrolysis ...
Caracterização e composição química do material particulado grosso (MP10) no centro da cidade de São Carlos (SP)
(Universidade Federal de São Carlos, 2015-03-27)
Coarse particulate matter with aerodynamic diameter smaller than 10μm (PM10) have long been considered as air pollutants associated with health issues. They penetrate into the upper respiratory tract, causing respiratory ...
Oxidação de monóxido de carbono sobre catalisadores à base de ferro ou manganês suportados ou trocados em zeólitas H-mordenita ou Ce-mordenita
(Universidade Federal de São Carlos, 2015-02-18)
The fluid catalytic cracking (FCC) is one of the most important process in the petroleum refining industry, being responsible for the increase of the yield of the most valuable light hydrocarbons. On the other hand, the ...
