Sugarcane bagasse was used as an inexpensive alternative carbon source for production of β-xylanases from Aspergillus terreus. The induction profile showed that the xylanase activity detected 6th day cultivation period. Two low molecular weight enzymes, named Xyl T1 and T2 were purified to apparent homogeneity by ultrafiltration, gel filtration ion exchange chromatographies presented masses 24.3and 23.60 kDa, determined SDS-PAGE, respectively. highest at 50 °C pH 6.0, while most active 45...
The saccharification of sugarcane bagasse by enzymatic hydrolysis is one the most promising processes for obtaining fermentable sugar to be used in production second-generation ethanol. objective this work was study immobilization and stabilization two commercial enzymes: Endocellulase (E-CELBA) dextran coated iron oxide magnetic nanoparticles activated with aldehyde groups (DIOMNP) β-glucosidase (E-BGOSPC) glyoxyl agarose (GLA) so that their immobilized derivatives could applied pretreated...
To improve the understanding of implications Campylobacterspp. infections in pets and children different environments were analysed 160 faecal samples from 120 (103 dogs 17 cats). Campylobacter spp. detected 6.87% 18.3% cats. From 33 stool positive for spp., 57.6% identified as C. jejuni, 33.4% coli. More than 50% isolates resistant to ceftiofur, sulphazotrim, norfloxacin tetracycline. In humans, most amoxicillin, cefazolin, erythromycin norfloxacin. 19 11 5 contained two four virulence...
Immobilization of lipase from Burkholderia gladioli BRM58833 on octyl sepharose (OCT) resulted in catalysts with higher activity and stability. Following, strategies were studied to further stabilize secure the enzyme support using functionalized polymers, like polyethylenimine (PEI) aldehyde-dextran (DEXa), cover catalyst layers at different combinations. Alternatively, construction a bifunctional layer was methoxypolyethylene glycol amine (NH 2 -PEG) glycine. The OCT-PEI-DEXa most...
Glucuronoyl esterases (CE15, EC 3.1.1.117) catalyze the hydrolysis of ester bonds between lignin and carbohydrates in lignocellulose. They are widespread within fungi bacteria, subjects to research interest due their potential applicability lignocellulose processing. Identifying new relevant glucuronoyl esterase candidates is challenging because available model substrates poorly represent natural substrate, which leads inefficient screening for activity. In this study, we demonstrate how...
The newly isolated Burkholderia gladioli BRM58833 strain was shown to secrete an alkaline lipase highly active and stable in organic solvents. Lipase production optimized through the cultivation of by solid-state fermentation wheat bran. extraction conditions were also optimized. low-cost extract obtained has a high hydrolytic activity 1096.7 ± 39.3 U·gds-1 (units per gram dry solids) against pNPP 374.2 20.4 triolein. Proteomic analysis revealed is composed two esterases three true lipases,...
