beta-glucosidase and beta-xylosidase production by a yeast-like Aureobasidium sp. was carried out during solid-state and submerged fermentation using different carbon sources and crude enzymes were characterized. beta-glucosidase and beta-xylosidase gave optimum activity at pH 2.0-2.5 and 3.0, respectively. These enzymes presented maximal activity at 65 degrees, and were stable in a wide pH range and high temperatures.
一株类酵母金色担子菌（Aureobasidium sp.）在固态和深层发酵过程中利用不同碳源生产β-葡萄糖苷酶和β-木糖苷酶，并对粗酶进行了表征。β-葡萄糖苷酶和β-木糖苷酶分别在pH 2.0 - 2.5和3.0时具有最佳活性。这些酶在65摄氏度时呈现最大活性，并且在较宽的pH范围和高温下都很稳定。
