Purification and Characterization of Two Xylanases from Alkalophilic Cephalosporium sp. Strain RYM-202.

摘要

Two different xylanases, CX-I and CX-II, from an alkalophilic fungus, Cephalosporium sp. strain RYM-202, have been purified to homogeneity. The enzymes had similar pH (7.5 to 8.0) and temperature (50(deg)C) optima and were stable over a wide pH range of 5.5 to 12.0. Both enzymes were shown to be cellulase-free endoxylanases with transglycosidation activity.
