采用滤纸片扩散法和生长速率法分别测定提取物对细菌、真菌的抑制作用;
经细菌发酵滤液处理后,变色菌菌丝变形,孢子不萌发或萌发产生不正常的芽管,如畸形、肿大,形成圆球状泡。
以可溶性淀粉为碳源,硝酸钠或硝酸钾为氮源有利于菌丝生长;
并且,都是在以甘氨酸和黄豆粉作为氮源和以玉米面和淀粉作为碳源菌丝生长势最强。
赤灵芝在其含量为30%时,平菇在25%时,菌丝生长最佳。
金银花、枸杞、甘草和黄芪对生物量增加有一定抑制作用。
结果表明,菌株间菌丝生长速度差异极显著,试管平面培养基测定菌丝生长速度误差小;
杀虫剂对球孢白僵菌的菌丝生长有一定抑制作用,抑制率为22.60%~38.39%;
本研究共选出菌丝生长速度配合力高的单孢菌株4个,杂交组合5个。
葡萄糖对菌丝生物量影响最大,高于淀粉和麦芽糖对菌丝生物量的影响。
试验表明:金针菇在虫粪浸提液含量为20%时菌丝生长最佳;
培养基营养条件对棉铃红粉病菌菌丝生长和孢子形成的影响
同一菌株分别在菌丝相和酵母相下对同一种抗真菌药物的MIC值不完全相同;
1·The degradation rate of lignin at the stage of mycelial growth was higher than that of cellulose and hemicellulose, facilitating the degradation of cellulose and hemicellulose of the fungus.
姬松茸在菌丝生长阶段木质素的降解速率大于纤维素和半纤维素,这对纤维素和半纤维素的降解十分有利。
