摘要: 为探讨冠突散囊菌在生长过程中分泌胞外酶的情况,通过平板水解圈法和液体发酵培养法定性定量研究冠突散囊菌在不同培养条件下产纤维素酶、蛋白酶、淀粉酶、果胶酶、脂肪酶的能力以及酶活性的动态变化规律。结果表明,固态培养条件下,淀粉平板和橄榄油脂平板培养基上可见明显的水解圈,而羧甲基纤维素钠平板、果胶平板和牛奶平板培养基上未见水解圈出现;液体发酵过程中,除未检测到脂肪酶外,纤维素酶、蛋白酶、淀粉酶和果胶酶活性均呈一定的趋势变化。

关键词: 冠突散囊菌, 胞外酶, 活性变化

Abstract: In order to explore extra-cellular enzyme secreted by Eurotium cristatum fungi, the enzymatic productivity and activity changes on carboxymethyl cellulase(CMCase), proteinase, amylase, pectinase and lipase were analyzed according to the methods of hydrolyzed circle and liquid cultivation. The results showed that there were obvious hydrolyzed circles appearsed on the plate medium with starch and olive oil, but not on plate medium with sodium carboxymethyl cellulose, pectin and milk. Except lipase, other enzymes were detected and their activities were varied obviously during liquid cultivation.

Key words: Eurotium cristatum, extra-cellular enzyme, activity changes
