Purification and characterization of xylanases from Aspergillus giganteus
(2004-04-20)
A strain of Aspergillus giganteus cultivated in a medium with xylan produced two xylanases (xylanase I and II) which were purified to homogeneity. Their molar mass, estimated by SDS-PAGE, were 21 and 24 kDa, respectively. ...
Assembling a xylanase-lichenase chimera through all-atom molecular dynamics simulations
(2013-10-14)
Multifunctional enzyme engineering can improve enzyme cocktails for emerging biofuel technology. Molecular dynamics through structure-based models (SB) is an effective tool for assessing the tridimensional arrangement of ...
Production and purification of an Endo–1,4-beta-Xylanase from Humicola grisea var. thermoidea by electroelution
(Sociedade Brasileira de Microbiologia, 2003-06-01)
Humicola grisea var. thermoidea produz duas formas de xilanase extracelular. A componente forma 1 foi purificada usando o método de eletroeluição devido à baixa produção desta enzima extracelular. A aparente massa molar ...
Optimization of xylanase biosynthesis by Aspergillus japonicus isolated from a Caatinga area in the Brazilian state of Bahia
(2006-06-02)
The objective of this research was to investigate the potential of xylanase production by Aspergillus japonicus and to determine the effects of cultivation conditions in the process, aiming toward optimization of enzyme ...
Xylanases from fungi: properties and industrial applications
(Springer, 2005-06-01)
Xylan is the principal type of hemicellulose. It is a linear polymer of beta-D-xylopyranosyl units linked by (1-4) glycosidic bonds. In nature, the polysaccharide backbone may be added to 4-O-methyl-alpha-D-glucuronopyranosyl ...
Production, purification, and characterization of a major penicillium glabrum xylanase using brewer's spent grain as substrate
(2013-06-12)
In recent decades, xylanases have been used in many processing industries. This study describes the xylanase production by Penicillium glabrum using brewer's spent grain as substrate. Additionally, this is the first work ...
Fontes de carbono de baixo custo para a produção de xilanase termoestável por aspergillus niger
(2013-04-01)
A strain of the flamentous fungus Aspergillus niger was isolated and shown to possess extracellular xylanolytic activity. These enzymes have biotechnological potential and can be employed in various industries. This fungus ...
Xilanase e β-glucanase na digestibilidade aparente de nutrientes do triticale pela Tilápia-do-nilo
(Universidade Federal de Minas Gerais (UFMG), Escola de Veterinária, 2010-04-01)
Avaliou-se o efeito de diferentes níveis do composto enzimático Natugrain Blend L®, que contém endo-xilanase e endo-beta-glucanase, sobre a digestibilidade dos nutrientes e a energia do triticale pela tilápia-do-nilo. O ...
