Application

β-glucosidase is also used in the synthesis of glucosides and fucosides with various potential applications in pharmaceutical, cosmetic and detergent industries, hydrolytic removal of aglycone moiety from flavonoid and isoflavonoid glycosides, flavor enhancement of fruit juices and wine, and biosynthesis of oligosaccharides.

Biochem/physiol Actions

βglucosidase is involved in the hydrolysis of β-glycosidic bonds connecting carbohydrate residues in β-D-glycosides. They convert cellobiose and cellooligosaccharides produced by the endo and exoglucanases to glucose.

Unit Definition

1 U corresponds to the amount of enzyme which liberates 1 μmol glucose per minute at pH 5.0 and 37 °C (salicin as substrate)

Biofilms of sulfate-reducing bacteria (SRB) produce H2 S, which contributes to corrosion. Although bacterial cells in biofilms are cemented together, they often dissolve their own biofilm to allow the cells to disperse. Using Desulfovibrio vulgaris as a model SRB, we
