Transferência de oxigênio e cisalhamento em biorreator convencional com diferentes combinações de impelidores
(Universidade Federal de São Carlos, 2016-02-26)
The type and operational conditions of a bioreactor chosen during the production phase of a product of interest affect not only the morphology and growth of filamentous microorganisms but also the product itself. Still the ...
Produção de sulfato de potássio a partir de cloreto de potássio e sulfato de amônio : estudos de equilíbrio sólido-líquido e desenvolvimento de processo
(Universidade Federal de São Carlos, 2016-02-29)
Potassium is one of the basic nutrients for plants and their concentration in the soil is
insufficient to produce high quality crops, so it should be an essential component in the
composition of fertilizers. Fertilizers ...
Avaliação das condições hidrodinâmicas, de transferência de oxigênio e de cisalhamento em diferentes modelos e escalas de reatores pneumáticos
(Universidade Federal de São Carlos, 2016-04-26)
Due to the high capacity of oxygen transfer and versatility, pneumatic reactors have been
constantly used in bioprocesses. However, aiming to expand the use of these bioreactors in the industry, as well as increase the ...
Obtenção e caracterização de linhagem de Escherichia coli adaptada ao glicerol bruto proveniente da síntese de biodiesel por engenharia evolutiva
(Universidade Federal de São Carlos, 2016-03-31)

Recuperação de lipase BTL-2 de Bacillus thermocatenulatus produzida em Escherichia coli recombinante empregando suportes magnéticos
(Universidade Federal de São Carlos, 2016-04-06)
Magnetic supports have gained attention because the magnetic separation is easy, has low cost and high efficiency. Moreover, it allows the purification and immobilization of a biomolecules in single step. Lipases are ...
Oxidação de CO sobre nanoestruturas controladas e de interiores vazios de AgPt dispersas em óxidos
(Universidade Federal de São Carlos, 2016-03-10)
The CO oxidation is considered one of the most studied reactions in heterogeneous catalysis. Although several studies have been developed in this field, the impact of some properties of catalysts, such as the oxygen mobility, ...
Estudo da produção de etanol de sacarose por fermentação extrativa utilizando arraste com dióxido de carbono
(Universidade Federal de São Carlos, 2016-04-18)
The ethanol accumulated in the broth during fermentation is the main component toxic to
yeast, causing slower yeast growth and decreased ethanol production. One way of overcoming
this inhibition effect is to use extractive ...
