Purification, characterization, and specificity determination of a new serine protease secreted by penicillium waksmanii
(2013-01-01)
The purpose of this work was to purify a protease from Penicillium waksmanii and to determine its biochemical characteristics and specificity. The extracellular protease isolated that was produced by P. waksmanii is a ...
Effect of Bacillus circulans D1 thermostable xylanase on biobleaching of eucalyptus kraft pulp
(2003-03-01)
The alkalophilic Bacillus circulans D1 was isolated from decayed wood. It produced high levels of extracellular cellulase-free xylanase. The enzyme was thermally stable up to 60°C, with an optimal hydrolysis temperature ...

Estabilização de enzimas: uma abordagem
(2010)
Enzyme stabilization is one critic point in basic and applied enzymology. The increasing interest in applying enzymes in industrial processes has fostered the search for biocatalysts with new properties or extreme stability. ...
Agroindustrial biomass for xylanase production by Penicillium chrysogenum: Purification, biochemical properties and hydrolysis of hemicelluloses
(2018-05-01)
Background: In this work, the xylanase production by Penicillium chrysogenum F-15 strain was investigated using agroindustrial biomass as substrate. The xylanase was purified, characterized and applied in hemicellulose ...
Produção de glicose e frutose por invertase de Saccharomyces cerevisiae imobilizada em suporte MANAE-agarose
(2013-06-27)
Invertase from Saccharomyces cerevisiae was immobilized on agarose beads, activated with various groups (glyoxyl, MANAE or glutaraldehyde), and on some commercial epoxy supports (Eupergit and Sepabeads). Very active and ...
Solid state production of thermostable pectinases from thermophilic Thermoascus aurantiacus
(2002-03-02)
Pectin lyase (Pl) and polygalacturonase (Pg) production by Thermoascus aurantiacus 179-5 was carried out by means of solid-state determination using orange bagasse and wheat bran as a carbon sources. Pg and Pl had optimum ...
