The optimum pH is 8-10 for hypha growth and 7-9 for conidiospore germination; The hypha could not grow on the culture medium which nitrogen source comes from urea and asparagines, but it could grow fast and produce more conidiospore on the culture medium which carbon source comes from maltose, glucose and lactose, and nitro0gen source come from glycine, histidiane and peptone.

该菌在PH 4~12范围内均能生长、产生分生孢子并萌发，菌丝生长的最适pH 8~10。，孢子萌发的最适PH 7~9；该菌不能在以尿素和天门冬酰氨为氮源的培养基上生长，但以麦芽糖、葡萄糖、乳糖、淀粉、甘氨酸、组氨酸和蛋白陈为碳源和氮源时，菌丝生长快、产孢量大；光照处理对该菌菌丝生长、产孢和孢子萌发无显著影响。
