Influência das condições de alimentação de glicerol e ornitina na produção de ácido clavulânico por Streptomyces clavuligerus
(Universidade Federal de São Carlos, 2008-03-26)
The clavulanic acid (CA) is a powerful inhibitor of β-lactamases, enzymes that clives the β-
lactam ring of penicillins and cephalosporins, inactivating these compounds. CA is
traditionally produced by Streptomyces ...
Avaliação de fontes de carbono e condições de indução na expressão de canacistatina em Escherichia coli BL21 (DE3)
(Universidade Federal de São Carlos, 2006-03-30)
Canecystatin (CC) is a competitive and reversible protease inhibitor which blocks the proteolytic enzymes activities of insets, fungus e nematodes, prejudicing thus the growth, development and reproduction from these ...
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 ...
Avaliação de coeficientes de rendimento e modelagem do processo fermentativo de produção de etanol
(Universidade Federal de São Carlos, 2008-10-30)
The yield ethanol (hP) is one of the most important parameters to be evaluated in the industrial process of alcohol fermentation. Because most plants neither present a
reasonable level of automation, nor perform frequent ...
Perovskitas La1-xSrxMnO3, suportadas em alumina e zircônia, aplicadas à combustão do metano
(Universidade Federal de São Carlos, 2007-08-28)
The total oxidation of the methane is an important environmental and industrial
reaction, mainly because it is extensively used in energy production and in the control
of gases emission to the atmosphere. With catalysts, ...
Análise da fluidodinâmica de calor em leito de jorro com alimentação contínua de sólidos pela base.
(Universidade Federal de São Carlos, 2004-08-19)
The objective of this work was to develop a theoretical and experimental study of fluid dynamics and heat transfer in a spouted bed with draft tube, which operates in continuous mode with particles feed through the bottom ...
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 ...
Isomerização de n-hexano sobre Pt-NiHUSY empregando zeolita com alto teor de Al.
(Universidade Federal de São Carlos, 2005-08-03)
The isomerization reactions of linear alkanes are very important to petrochemical industries due to the isomer products in reaction possess high octane number. The majority of the literature articles involves the job ...
Caracterização metabólica e cinética do cultivo de três hibridomas para produção de imunoglobulinas com especificidade e antígenos eritrocitários para uso hemoterápico.
(Universidade Federal de São Carlos, 2007-03-30)
In the last two decades mammalian cell cultures have been broadly used for the
industrial production of pharmaceutical, proteins, in particular the monoclonal antibodies by
cultures of murine hybrid cells (hybridoma). The ...
Estudo da imobilização de celulase em géis de quitosana.
(Universidade Federal de São Carlos, 2007-01-29)
Cellulases are enzymes that catalyze the hydrolysis of cellulose producing glucose.
Immobilization and stabilization of these enzymes could improve enzymatic process making
it more attractive by reducing costs during their ...
