Background: Zymomonas mobilis is an efficient ethanol fermentation strain, but its narrow substrate range limits its fermentation in lignocellulose hydrolysate. As a potential consolidated bioprocessing (CBP) stain for bioethanol production, the ability of cellulose utilization was necessary. In this study, extracellular expression of β-glucosidase on Z. mobilis was studied as the first step fo...
β-Glucosidase is an important enzyme for production of ethanol from lignocellulose. With hydrolytic activity on cellooligosaccharides, especially cellobiose, β-glucosidase removes product inhibitory effect on cellulases and forms fermentable sugars. In this study, β-glucosidase encoding gene (BGL1) from traditional starter yeast Saccharomycosis fibuligera BMQ908 was cloned and expressed in Pich...
Production of β-glucosidase from Fusarium oxysporum was investigated during degradation of some cellulosic substrates (Avicel, α-cellulose, carboxymethyl cellulose (CMC), and methylcellulose). Optimized production of β-glucosidase using the cellulosic substrate that supported highest yield of enzyme was examined over 192 h fermentation period and varied pH of 3.0-11.0. The β-glucosidase produce...
β-glucosidase is a crucial element of the microbial cellulose multienzyme complex since it is responsible for the regulation of the entire cellulose hydrolysis process. Therefore, the aim of the present work was to explore the diversity and distribution of glycosyl hydrolase family 1 β-glucosidase genes in three different environmental niches including, Himalayan soil, cow dung and compost by m...
The ability of probiotic strain Lactobacillus plantarum LS/07 to modify the activity of intestinal bacterial enzymes - β-glucuronidase (β-GLUCUR), β-galactosidase (β-GAL), and β-glucosidase (β-GLU) in prevention of chronic diseases - cancer, atherosclerosis and dysbiosis was investigated. The male Sprague-Dawley rats were randomly divided into 12 experimental groups: controls groups - C (contro...
β-Glucosidase (EC 3.2.1.21) is a prominent member of the GH1 family of glycoside hydrolases. The properties of this β-glucosidase appear to include resistance to temperature, urea, and iodoacetamide, and it is activated by 2-ME, similar to other members. β-Glucosidase from chayote (Sechium edule) was purified by ionic-interchange chromatography and molecular exclusion chromatography. Peptides d...
β-Glucosidase hydrolyzes cellobiose to glucose and is an important enzyme in the consortium used for hydrolysis of cellulosic and lignocellulosic feedstocks. In the present work, β-glucosidase was covalently immobilized on non-porous magnetic particles to enable re-use of the enzyme. It was found that particles activated with cyanuric chloride and polyglutaraldehyde gave the highest bead-relate...
BACKGROUND The study on the second generation bio-fuel is a hot area of current research of renewable energy. Among series of key points in this area, the role of β-glucosidase in the degradation of intermediate gluco-oligosaccharides limits the rate of the complete saccharification of lignocellulose. RESULTS In this study, a new β-glucosidase gene, unglu135B12, which was isolated from a meta...
Elizabethkingia sp. BM10 was isolated from the hindgut of the wood-feeding termite Reticulitermes speratus KMT1. It had cellobiohydrolase and β-glucosidase activities but not endo-β-glucanase activity. The complete sequence of its genome, which has a total size of 4,242,519 bases, is reported here. The genomic analysis identified six β-glucosidase candidate genes and three β-glucanase candidate...
BACKGROUND Cold-active enzymes, sourced from cold-adapted organisms, are characterized by high catalytic efficiencies at low temperatures compared with their mesophilic counterparts, which have poor activity. This property makes them advantageous for biotechnology applications as it: (i) saves energy costs, (ii) shortens the times for processes operated at low temperatures, (iii) protects therm...
