【摘要】 该文研究了毛霉M2产蛋白酶的若干影响因素,包括培养基的成分以及发酵条件等。结果表明:在麸皮与水的合适比例为1:0.8;在基本培养基上添加一定浓度的碳源、氮源及无机盐有利于蛋白酶的合成;菌体较为合适的产酶条件为温度28℃,pH6.0,发酵时间36h。更多还原

【Abstract】 Factors influencing the protease production with Mucor M2, including the ingredient of medium and fermentation conditions were studied in this paper. The result showed that the proper ratio of bran and water was 1: 0.8; adding certain concentration of carbon, nitrogen, and minerals sources improved the production of protease; the optimal fermentation conditions were at 28℃ for 36 h when pH was 6.0.更多还原
