Properties and applications of microbial beta-D-xylosidases. Applied Microbiology and Biotechnology. 86(6):1647-1658 Interpretive Summary: Xylan 1,4-beta-D xylosidase catalyzes hydrolysis of nonreducing end xylose residues from xylooligosaccharides. The enzyme is currently used in several industrial-scale processes for food and materials, and on a grander scale, the enzyme could find employment along side cellulases and other hemicellulases in hydrolyzing lignocellulosic biomass so the reaction product monosaccharides can be fermented to biofuels, ethanol and butanol. Catalytically efficient enzyme, performing under saccharification reactor conditions, is critical to the feasibility of enzymatic saccharification processes. This is particularly important for beta-xylosidase which would catalyze breakage of more glycosidic bonds of hemicellulose than any other hemicellulase.
