An alkalophilic lignocellulosic decomposing fungus WL002 was isolated and identified.
A 尾-glucosidase gene was cloned from newly isolated A. fumigatus WL002.
尾-glucosidase purified from E. coli had pH optima in the alkaline range.
Enzyme displayed the higher activity against p-nitrophenyl-尾-class="smallcaps">d-glucopyranoside.
Alkali 尾-glucosidase was a likely catalyst for biodegradation of cellulosic biomass.
