EG1 is a modular glycoside hydrolase family 5 endoglucanase from Volvariella volvacea consisting of an N-terminal carbohydrate-binding module (CBM1) and a catalytic domain (CD). The ratios of soluble to insoluble reducing sugar produced from filter paper after 8 and 24 h of exposure to EG1 were 6.66 and 8.56, respectively, suggesting that it is a processive endoglucanase. Three derivatives of E...

BACKGROUND Working at high solids (substrate) concentrations is advantageous in enzymatic conversion of lignocellulosic biomass as it increases product concentrations and plant productivity while lowering energy and water input. However, for a number of lignocellulosic substrates it has been shown that at increasing substrate concentration, the corresponding yield decreases in a fashion which c...

1 Ionic liquids (ILs) dissolve lignocellulosic biomass and have a high potential as pretreatment 2 prior to total enzymatic hydrolysis. ILs are, however, known to inactivate cellulases. In this 3 article, enzymatic hydrolysis of microcrystalline cellulose (MCC) and enzyme binding onto 4 the cellulosic substrate were studied in the presence of cellulose-dissolving ionic liquids. Two 5 different ...

Astonishingly uniform polypyrrole nanocoating on morphologically complex cellulosic substances was achieved without disrupting the hierarchical network structures of individual cellulose fibers by means of polymerization-induced adsorption.

This work aims to investigate the physical and mechanical properties of sisal fiber yarn Moroccan origin. The cellulosic non-cellulosic constituents were identified by FTIR spectroscopy. thermal studied thermogravimetric analysis. hydrophilicity was evaluated contact angle. results show that has a low stability. analyzed Impregnated Fiber Bundle Test (IFBT) method porosity impregnated yarns twi...

A thermophilic strain AMF-07, hydrolyzing carboxymethylcellulose (CMC) was isolated from Kerman hot spring and was identified as Bacillus licheniformis based on 16S rRNA sequence homology. The carboxymethylcellulase (CMCase) enzyme produced by the B. licheniformis was purified by (NH4)2SO4 precipitation, ion exchange and gel filtration chromatography. The purified enzyme gave a single band on S...

Previous work at the University of New Mexico and elsewhere has shown that sulfate-reducing bacteria are capable of reducing uranium from the soluble +6 oxidation state to the insoluble +4 oxidation state. This chemistry forms the basis of a proposed ground water remediation strategy in which microbial reduction would be used to immobilize soluble uranium. One such system would consist of a sub...
