Seleção de suportes e protocolos de imobilização de lipases para a síntese enzimática de biodiesel
(Universidade Federal de São Carlos, 2009-05-25)
The objective of this thesis was to prepare and select immobilized lipase derivatives with high catalytic activity and thermal stability to mediate the biodiesel synthesis from palm and babassu oils by ethanolic route. The ...
Hidrodinâmica e transferência de oxigênio em três biorreatores Airlift de circulação interna geometricamente semelhantes
(Universidade Federal de São Carlos, 2009-03-12)
Internal-loop airlift reactors (ALR) are a special class of pneumatic reactors. The use of this type of reactor has been attractive for chemical and biological reactions because of their simple construction without moving ...
Modelo matemático do processo de purificação do ácido clavulânico por troca iônica em coluna de leito fixo
(Universidade Federal de São Carlos, 2009-08-04)
Clavulanic acid (CA) is a β-lactam antibiotic produced industrially by submerged cultures of the filamentous bacterium Streptomyces clavuligerus. Due to its importance, several studies on the purification of clavulanic ...
Aplicação de peneiras moleculares contendo cátions orgânicos em catálise básica
(Universidade Federal de São Carlos, 2008-12-12)
This thesis was aimed at studying novel basic catalysts based on molecular sieves containing alkylammonium cations. The studied molecular sieves were faujasite zeolites (FAU) and mesoporous silicate (like MCM-41). The ...
Secagem de sementes de gramíneas (Brachiaria brizantha) em leito fluidizado
(Universidade Federal de São Carlos, 2008-12-05)
Drying operation is an important stage of the processing that precedes the storage of seeds, since that with low moisture contents, these can retain their power of germination and other qualities for long periods. The ...
Hidrólise controlada de proteínas de soro lático usando tripsina e quimotripsina imobilizadas em diferentes suportes.
(Universidade Federal de São Carlos, 2004-11-30)
This work is part of a global project whose aim is the production of a cheese
whey proteins hydrolysate with controlled composition. The process is composed by
sequential hydrolysis of the whey proteins using trypsin, ...
