木霉菌Tr01菌株分生孢子萌发影响因子研究
Journal of Shenyang Agricultural University（2005）
Abstract
研究了不同的温度、湿度、光照、pH值、碳源、氮源、微量元素等条件对木霉菌Tr01菌株孢子萌发影响作用.结果表明:25～30℃及高湿环境是木霉菌Tr01菌株分生孢子萌发的适宜温湿度条件,光照对孢子萌发无影响;分生孢子在pH值6～5的弱酸环境下萌发最好;碳源中,麦芽糖能极大地促进孢子萌发,蔗糖、葡萄糖对孢子萌发具有一定的促进作用;有机氮源的蛋白胨对孢子萌发具有极大促进作用,无机氮源中NH4Cl、NH4NO3也能较好地促进孢子萌发,KNO3、NaNO3等则对萌发无促进作用;微量元素中一定浓度的MnSO4·4H2O、ZnSO4·7H2O能够明显地促进孢子萌发.
