Abstract
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.
摘要
两株来自嗜堿真菌 Cephalosporium sp. strain RYM-202 的木聚糖酶 CX-I 和 CX-II 已被纯化为均一状态。这两种酶具有相似的最适 pH（7.5 至 8.0）和温度（50°C），并且在 5.5 至 12.0 的宽 pH 范围内稳定。这两种酶均为无纤维素内切木聚糖酶，具有转糖苷活性。
