Complete saccharification of cellulose at high temperature using endocellulase and beta-glucosidase from Pyrococcus sp.
We investigated a potential for glucose production from cellulose material using two kinds of hyperthermophilic enzymes, endo-cellulase (EG) and beta-glucosidase (BGL). Two BGLs from hyperthermophile Pyrococcus furiosus and mesophile Aspergillus aculeatus were compared for complete hydrolysis of cellulose with P. horikoshii endo-cellulase (EGPh). The combination reactions by each BGL enzyme and...
متن کاملPurification and characterization of an alpha-glucosidase from Rhizobium sp. (Robinia pseudoacacia L.) strain USDA 4280.
A novel alpha-glucosidase with an apparent subunit mass of 59 +/- 0. 5 kDa was purified from protein extracts of Rhizobium sp. strain USDA 4280, a nodulating strain of black locust (Robinia pseudoacacia L), and characterized. After purification to homogeneity (475-fold; yield, 18%) by ammonium sulfate precipitation, cation-exchange chromatography, hydrophobic chromatography, dye chromatography,...
متن کاملMicrobacterium ginsengiterrae sp. nov., a beta-glucosidase-producing bacterium isolated from soil of a ginseng field.
Strain DCY37(T) was isolated from a soil sample of a ginseng field in the Republic of Korea and characterized in order to determine its taxonomic position. Cells were Gram-staining-positive, heterotrophic, strictly aerobic, non-motile short rods. 16S rRNA gene sequence analysis revealed that strain DCY37(T) belongs to the genus Microbacterium. According to 16S rRNA gene sequence analysis, it is...
متن کاملImmobilization of Aspergillus beta-glucosidase on chitosan.
beta-Glucosidase of Aspergillus phoenicis QM 329 was immobilized on chitosan, using the bifunctional agent glutaraldehyde. The most active preparation based on the amount of support contained a 1:2.5 enzyme-to-chitosan ratio (wt/wt). However, the specific activity of the bound enzyme decreased from 10 to 1% with increasing enzyme-to-chitosan ratio. Compared with free beta-glucosidase, the immob...
متن کاملA novel tannase from Aspergillus niger with beta-glucosidase activity.
An extracellular tannase was produced from solid-state cultures of Aspergillus niger. The enzyme was purified to homogeneity from the cell-free culture broth by preparative isoelectric focusing and by FPLC using anion-exchange and gel-filtration chromatography. SDS-PAGE analysis as well as gel localization studies of purified tannase indicated the presence of two enzyme forms, with molecular ma...
