Pré-tratamento do bagaço de cana de açúcar com amônia aquosa para a produção de etanol
(Universidade Federal de São Carlos, 2011-02-28)
The aim of this work was evaluated the sugarcane bagasse (SCB) pretreatment by aqueous ammonia, an alkaline method. Samples of SCB (in natura and steam exploded unwashed) were pretreated with ammonium hydroxide solution ...
Avaliação diferencial de fatores fisiológicos e cinéticos em cultivos de linhagens de células selvagem e recombinante de Drosophila melanogaster S2
(Universidade Federal de São Carlos, 2005-09-19)
In the last 10 years the insect cell Drosophila melanogaster Schneider S2 has been increasingly used for studies of proteins recombinants. However, there is a lack of studies that involved parameters related to the use of ...
Separação e purificação do ácido clavulânico através de extração líquido-líquido seguida de adsorção em coluna de leito fixo.
(Universidade Federal de São Carlos, 2005-10-19)
A study was made of the extraction of clavulanic acid (CA) from a fermented medium and
its concentration and purification, based on a comparison of two liquid-liquid extraction
methods, followed by adsorption in a fixed ...
Estudo da expressão de lipase BTL2 de Bacillus thermocatenulatus em E. coli recombinante
(Universidade Federal de São Carlos, 2009-04-03)
Using recombinant DNA techniques, the lipase BTL2 gene of Bacillus thermocatenulatus was cloned in E. coli BL321 under control of the strong temperature-inducible λPL promoter. It
was investigated, initially, in this ...
Contribuição ao desenvolvimento de metodologia para detecção de desintegrina recombinante produzida em cultivos de células CHO-K1.
(Universidade Federal de São Carlos, 2004-06-25)
Disintegrins are proteins present in the poison of serpents that have been calling the pharmaceutical industry attention due to their capacity to prevent the progression of cancerous cells. A receiving key-protein called ...
Estudo da cinética e do equilíbrio da adsorção da cefamicina C em resina de troca iônica e simulação do processo contínuo
(Universidade Federal de São Carlos, 2011-03-01)
The cephamycin C (CefC) is a beta-lactam antibiotic produced from submerged and aerated cultures of Streptomyces clavuligerus. Acts as inhibitor of cell wall formation of Gram-negative bacteria and is resistant to the ...
Produção de ácido clavulânico por Streptomyces clavuligerus em cultivos em batelada e batelada alimentada com pulsos de glicerol sob diferentes condições de temperatura
(Universidade Federal de São Carlos, 2010-03-25)
The production of enzymes β-lactamases by pathogenic bacteria is the most common mechanism of resistance to β-lactam antibiotics. The β-lactamases catalyze the hydrolysis of β-lactam ring, splitting the ...
Otimização dinâmica do cultivo semi-contínuo de Pichia pastoris recombinante para produção das enzimas heterólogas alfa amilase e penicilina G acilase
(Universidade Federal de São Carlos, 2010-03-31)
This master's thesis project aims at studying the dynamic optimization of the operation of a bench scale (up to 5L) automated, agitated and aerated bioreactor, where the semi-continuous cultivation of recombinant Pichia ...
Separação de ampicilina produzida enzimaticamente por reação entre éster metílico de fenilglicina e ácido 6-aminopenicilânico.
(Universidade Federal de São Carlos, 2003-11-07)
The separation/concentration process of the products obtained from the enzymatic synthesis of ampicillin (AMP) catalyzed by immobilized penicillin G acylase was the focus of this Thesis. Hydrophobic resin adsorption and ...
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 ...
