The research on the conditions of chlamydospore production for the liquid fermentation showed that, the better single factors were oat liquid media, 30℃, 120r/min surge culture, sucrose as carbon source,(NH_4)_2SO_4 as nitrogen source and the ratio of 20 to 1 for C/N. Under the better single factors mentioned above, the largest quantity of chlamydospore, i.e.3.05×10~7spores/ml, was obtained on the 10th day after culture.
木霉T-33菌株产生厚垣孢子的发酵条件研究表明,采用燕麦粉培养液、30℃、120r/min振荡培养、250ml三角瓶装入80ml培养液、接种5片活化2d的5mm直径的菌片,碳氮源选择蔗糖和硫酸铵,C/N为20/l,足适合T-33菌株产孢的最佳单因素条件(碳氮源实验基于Czapek培养基);用这些最佳单因素组合(不包括碳氮源和C/N结果)培养木霉T-33绘制了产孢曲线,发现在培养第10d得到最大的厚垣孢子产量3.05×10~7个/ml。
