【摘要】 研究了毛霉M4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;在基本培养基基础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】 Some influence factors of the mucor proteinase preparation by solid state fermentation,including the ingredient of medium and fementation conditions were studied.The results show that the proper propotion of bran and water is 1∶0.8,adding some carbom sources nitrogen sources and minerals to the elementary medium can improve the production of mucor proteinase.The proper fermentation conditions are temperation28℃,pH6.0,time 36 hours.更多还原
