The kinetics of a thermostable extracellular acid protease produced by an Aspergillus foetidus strain was investigated at different pH, temperatures and substrate concentrations. enzyme exhibited maximal activity pH 5.0 55°C, its irreversible deactivation well described first-order kinetics. When temperature raised from 55 to 70°C, the rate constant increased 0.018 5.06h(-1), while half-life decreased 37.6 0.13h. results collected were then used estimate, activation energy hydrolysis...
Abstract Recent decades have seen the growth of immense interest in lignocellulosic biomass conversion technologies. This is motivated by their huge potential for energy and bioproduct generation reduced dependency on non‐renewable feedstocks, leading to improved air quality emission greenhouse gases. It this context that lignocellulose biorefinery concept arises. Among technologies available, enzymatic has emerged as a promising candidate, since it represents management approach integrates...
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...
Enzymatic hydrolysis is an important but expensive step in the process to obtain enzyme derived products. Thus, production of efficient enzymes great interest for this biotechnological application. The xylanase by Aspergillus foetidus soybean residues was optimized using 2 × 23 factorial designs. experimental data fitted into a polynomial model activity. Statistical analyses results showed that variables pH and interaction temperature had influenced xylanase, with best level (13.98 U/mL)...
β-Galactosidases are widely used for industrial applications. These enzymes could be in reactions of lactose hydrolysis and transgalactosylation. The objective this study was the production, purification, characterization an extracellular β-galactosidase from a filamentous fungus, Aspergillus niger. enzyme production optimized by factorial design. Maximal activity (24.64 U/mL) found system containing 2% soybean residue (w/v) at initial pH 7.0, 28 °C, 120 rpm 7 days. ANOVA optimization...
Aspergillus tamarii grows abundantly in naturally composting waste fibers of the textile industry and has a great potential biomass decomposition. Amongst key (hemi)cellulose-active enzymes secretomes biomass-degrading fungi are lytic polysaccharide monooxygenases (LPMOs). By catalyzing oxidative cleavage glycoside bonds, LPMOs promote activity other lignocellulose-degrading enzymes. Here, we analyzed catalytic two seven AA9-type that were detected recently published transcriptome data for...
