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 ...
Redução de cromo hexavalente utilizando-se filmes de polímeros condutores como materiais eletródicos.
(Universidade Federal de São Carlos, 2003-06-16)
In this work we studied a three-dimensional electrode (reticulated vitreous carbon, CVR), modified with conducting polymer films, for the electrochemical reduction of Cr(VI). First of all, the conducting polymers polyaniline ...
Operação periódica de um leito gotejante de carvão ativado para redução da emissão do poluente atmosférico SO2 com geração de ácido sulfúrico.
(Universidade Federal de São Carlos, 2003-06-23)
A laboratory-scale investigation of SO2 scrubbing was carried out in a 77.92mm (diameter) × 80.00mm trickle bed with 2.00-2.36mm activated carbon particles using continuous and periodically interrupted liquid flows. The ...
Incorporação de titânio na peneira molecular Mor e suas propriedades.
(Universidade Federal de São Carlos, 2003-08-14)
The titanium incorporation in the MFI structure generated a new material, called TS-1, which showed highly active in oxidation reactions of organic compounds. A very important aspect in this titanium-silicate is that it ...
Síntese enzimática de ampicilina em reator integrado.
(Universidade Federal de São Carlos, 2004-02-11)
Enzymatic route to produce antibiotic acts in mild reaction conditions
(aqueous medium, neutral pH and moderate temperatures). Furthermore it reduces
the number of reaction steps and decreases the amount and toxicity of ...
Determinação da carga eletrostática em aerossóis e seu efeito na filtração de gases.
(Universidade Federal de São Carlos, 2005-05-06)
It has been shown that the presence of electrostatic charges in particles affects
significantly the performance of a filter, both increasing collection efficiency and reducing
pressure drop. The aim of the present work is ...
Diferentes meios de cultivo e condições operacionais na produção de penicilina G acilase por Bacillus megaterium.
(Universidade Federal de São Carlos, 2007-08-16)
Penicillin G acylase (PGA) is an important enzyme for industry, used to produce
aminopenicillanic acid, a key intermediate in the synthesis of ampicillin, among other betalatam
antibiotics. The production of this enzyme ...
Reator enzimático de membrana para proteólise de soro de queijo, visando à produção de concentrado protéico com baixo teor de fenilalanina
(Universidade Federal de São Carlos, 2007-12-07)
Enzymatic hydrolyzed proteins present some advantages over the pool of
amino acids obtained after a chemical hydrolysis: lower osmolality (easier absorption by the
organism) and better sensorial characteristics. The removal ...
