Avaliação de transferência de calor e massa em biorreator Airlift de bancada para a produção de ácido clavulânico.
(Universidade Federal de São Carlos, 2005-03-28)
The importance of the airlift bioreactor has grown in the biotechnology
field by aspects as high oxygen transfer, with power input low.
In this work were study the conditions heat and mass transfer, as well
as the condenser ...
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 ...
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 ...
