Controle nebuloso ("fuzzy”) aplicado à combustão em caldeiras a bagaço de cana
(Universidade Federal de São Carlos, 2018-04-26)
In the sugarcane industry, boilers are widely used for cogeneration. This term designates the simultaneous generation of more than one type of energy, namely thermal and electrical, from the same fuel source. This industry ...
Desenvolvimento de sistema nebuloso (fuzzy) para controle do oxigênio dissolvido no cultivo de escherichia coli para expressão de proteínas recombinantes
(Universidade Federal de São Carlos, 2018-02-26)
One very important bioprocess is the cultivation of recombinant E. coli for expression of heterologous proteins. For this, High Cell Density Culture is one of the most widely used technique. Although it results in cell ...
Parâmetros cinéticos da cristalização de sacarose em diferentes escalas
(Universidade Federal de São Carlos, 2018-03-07)
This work aims to determine kinetic parameters capable of describing the crystallization of sucrose using bench scale and pilot scale reactors. Sucrose was chosen because it is a very important product for Brazil, which ...
Estratégias para a síntese de agregados reticulados porosos de lipase de pâncreas de porco com propriedades magnéticas
(Universidade Federal de São Carlos, 2019-02-28)
Cross-linked enzyme aggregates (CLEAs) is an immobilization technique that does not require solid support, allows the use of semi-purified enzymes and the biocatalyst show higher volumetric activity. However, they present ...
Solubilização biológica de rocha potássica para aplicação como biofertilizante
(Universidade Federal de São Carlos, 2020-02-18)
Potassium (K) plays an important role in several biochemical and physiological processes in plants, but the low concentrations of soluble K in the soil make it necessary to use chemical fertilizers in order to supply the ...
Extração e caracterização cinético de lipase ácida presente na semente de mamona
(Universidade Federal de São Carlos, 2019-02-26)
Several studies have been conducted regarding acidic lipase from castor bean seed, most of them using the enzyme in the form of solid seed extract (SSE), which is extracted through grinding and removal of the oil. Kinetic ...
Modelagem e simulação da produção de biossurfactante em biorrefinaria integrada biodiesel-bioetanol
(Universidade Federal de São Carlos, 2020-03-02)
Biosurfactants are amphipathic molecules produced by enzymatic or microbiological routes. Biosynthesis can occur by esterifying sugars with fatty acids, with lipase as the main enzyme that catalyzes the reaction. However, ...
Contribuições ao estudo da secagem da borra de café em leito vibrofuidizado
(Universidade Federal de São Carlos, 2019-03-15)
Brazil is the largest producer of coffee in the world, half of this production is destined to the soluble coffee industry, that generates a amount of waste. The spent coffee grounds leave the fabrication processo f the ...
Monitoramento da hidrólise enzimática de bagaço de cana-de-açúcar por métodos espectrofotométricos
(Universidade Federal de São Carlos, 2020-02-23)
The production process of 2nd generation ethanol (2G), using sugarcane bagasse, is a promising way to increase ethanol production without increasing the cultivation area. However, the process has been studied to become ...
Análise térmica da fermentação alcoólica convencional e extrativa com arraste por dióxido de carbono
(Universidade Federal de São Carlos, 2020-02-18)
Extractive fed-batch ethanol fermentation using carbon dioxide (CO2) as striping gas has several advantages compared to the conventional fermentation, such as: reducing the effect of ethanol inhibition, allowing to use ...
