Modulation of the activity and selectivity of the immobilized lipases by surfactants and solvents
(Biochemical Engineering Journal, 2015) [Artigo]
Most of lipases are in equilibrium between a majority inactive closed form and a minority active open form in aqueous media. Perhaps, a certain stabilization of these open forms of lipases could be achieved in the presence ...
Screening of bacterial strains for pectinolytic activity: characterization of the polygalacturonase produced by Bacillus sp
(Revista de Microbiologia, 1999-12-01) [Artigo]
A partir de amostras de solo e de material vegetal em decomposição, foram isoladas 168 linhagens bacterianas capazes de utilizar pectina de citrus como única fonte de carbono. Destas, 102 foram positivas para a despolimerização ...
Evaluation of the beta-glucanolytic enzyme complex of Trichoderma harzianum Rifai for the production of gluco-oligosaccharide fragments by enzymatic hydrolysis of 1,3;1,6-beta-D-glucans
(Current Research Topics In Applied Microbiology and Microbial Biotechnology, 2009-01-01) [Trabalho apresentado em evento]
Botryosphaeran, a new exopolysaccharide from the endophytic fungus Botryosphaeria rhodina MAMB-05, and algal laminarin were hydrolyzed by partially-fractionated enzymes of the beta-glucanolytic complex from Trichoderma ...
Selection of the best source of carbon for production of recombinants enzymes in liquid fermentation
(Journal of Biotechnology, 2010-11-01) [Resumo]
Biochemical and Functional Characterization of a Metalloprotease from the Thermophilic Fungus Thermoascus aurantiacus
(Journal of Agricultural and Food Chemistry, 2009-10-14) [Artigo]
Protease production was carried out in solid state fermentation. The enzyme was purified through precipitation with ethanol at 72% followed by chromatographies in columns of Sephadex G75 and Sephacryl S100. It was purified ...
Phenolic Composition of the Edible Parts (Flesh and Skin) of Bordo Grape (Vitis labrusca) Using HPLC-DAD-ESI-MS/MS
(Journal of Agricultural and Food Chemistry, 2011-12-28) [Artigo]
The aim of this study was the detailed characterization of the phenolic composition and the determination of the antioxidant activity of the Bora grape (Vitis labrusca) cultivated in South Brazil. The edible parts of Bora ...
Evaluation of solid and submerged fermentations for the production of cyclodextrin glycosyltransferase by Paenibacillus campinasensis H69-3 and characterization of crude enzyme
(Applied Biochemistry and Biotechnology, 2006-03-01) [Artigo]
Cyclodextrin glycosyltransferase (CGTase) is an enzyme that produces cyclodextrins from starch by an intramolecular transglycosylation reaction. Cyclodextrins have been shown to have a number of applications in the food, ...
Chemical composition and antioxidant activity of dried powder formulations of Agaricus blazei and Lentinus edodes
(Food Chemistry, 2013-06-15) [Artigo]
Several mushroom species have been pointed out as sources of antioxidant compounds, in addition to their important nutritional value. Agaricus blazei and Lentinus edodes are among the most studied species all over the ...
Utilização do resíduo líquido de indústria de processamento de suco de laranja como meio de cultura de Penicillium citrinum: depuração biológica do resíduo e produção de enzima
(Química Nova, 1998-11-01) [Artigo]
Penicillium citrinum grown in orange juice processing wastes medium under continuous agitation was studied in order to establish optimal conditions (incubation period, incubation temperature, initial pH and nitrogen addition) ...
Production and characteristics comparison of crude beta-glucosidases produced by microorganisms Thermoascus aurantiacus e Aureobasidium pullulans in agricultural wastes
(Enzyme and Microbial Technology, 2008-11-06) [Artigo]
The purified beta-glucosidase of Aureobasidium pullulans ER-16 is one of more thermostable enzyme reported to date. Considering the unfeasibility of using purified enzyme for industrial application, it was interesting to ...
