Background Saccharification is the most crucial and cost-intensive process in second generation biofuel production. The deficiency of β-glucosidase in commercial enzyme leads to incomplete biomass hydrolysis. The decomposition of biomass at high temperature environments leads us to isolate thermotolerant microbes with β-glucosidase production potential. Results A total of 11 isolates were obt...

Background Compost habitats sustain a vast ensemble of microbes that engender the degradation of cellulose, which is an important part of global carbon cycle. β-Glucosidase is the rate-limiting enzyme of degradation of cellulose. Thus, analysis of regulation of β-glucosidase gene expression in composting is beneficial to a better understanding of cellulose degradation mechanism. Genetic diversi...

A soil microorganism producing αand β-glucosidase inhibitors was identified as Bacillus lentimorbus, based on the fatty acid and morphological analyses, along with biochemical and physiological tests. The α-glucosidase inhibitor was highly produced by this strain in a culture medium containing 0.25% of sodium glutamate and 0.5% of glucose, pH 8.0 at 30C for 2 days. The α-glucosidase inhibitor f...

Bioethanol production from lignocellulose is considered as a sustainable biofuel supply. However, the low cellulose hydrolysis efficiency limits the cellulosic ethanol production. The cellulase is strongly inhibited by the major end product cellobiose, which can be relieved by the addition of β-glucosidase. In this study, three β-glucosidases from different organisms were respectively expressed...

The objective of the presented study was to examine the influence of Fusarium mycotoxins (zearalenone--ZEN and deoxynivalenol--DON), administered separately and in combination, on the activity of cecal enzymes (β-glucosidase and β-glucuronidase) in gilts which were fed fodder con- taminated with these mycotoxins. The activity of β-glucosidase and β-glucuronidase varied in the range of 0.170-1.2...

β-Glucosidase, which hydrolyzes cellobiose into two glucoses, plays an important role in the process of saccharification of the lignocellulosic biomass. In this study, we optimized the activity of β-glucosidase of brown-rot fungus Fomitopsis pinicola KCTC 6208 using the response surface methodology (RSM) with various concentrations of glucose, yeast extract and ascorbic acid, which are the most...
