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 ...
Preparação e caracterização de sílicas híbridas com surfactantes catiônicos
(Universidade Federal de São Carlos, 2018-02-16)
The silica with structure MCM-41 has a hexagonal mesoporous arrangement with one dimensional pore system. This silica as synthesized contains cations (usually the CTA+) in your pores and catalytic sites with basic character ...
Influência da morfologia e do cisalhamento na produção de enzimas celulolíticas por Aspergillus niger
(Universidade Federal de São Carlos, 2020-03-26)
Issues related to sustainability and development of renewable and less polluting processes are increasingly in evidence, due to the various environmental crises and a greater concern with the scarcity of non-renewable ...
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 ...
Avaliação da secagem convectiva de resíduos da indústria cervejeira
(Universidade Federal de São Carlos, 2020-03-05)
Brazil is the third largest beer producer in the world, with an estimated production of 14.1 billion liters of the product for the year 2018, generating several co-products throughout the process, being brewer’s spent grain ...
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, ...
