ASPERGILLUS NIGER BETA-GLUCOSIDASE GENE, THE ENZYME PRODUCED THEREFROM AND USES THEREOF

摘要

A polypeptide having β-glucosidase enzymatic activity, a polynucleotide encoding the polypeptide, a nucleic acid constructs carrying the polynucleotide, transformed or infected cells, such as yeast cells, and transgenic organisms expressing the polynucleotide and various uses of the polypeptide, the polynucleotide, cells and/or organisms, including, producing a recombinant polypeptide having the β-glucosidase enzymatic activity, increasing the level of aroma compounds in alcoholic beverages, as well as other fermentation products of plant material, hydrolyzing cellobiose and thus increasing the level of fermentable glucose, increasing the production of alcohol, such as ethanol from plant material, increasing the aroma released from a plant or a plant product, and hydrolysis or transglycosylation of glycosides.
