【摘要】 通過對Pm0217F菌株進行不同時間梯度的紫外誘變,得到5株不同的誘變菌株。通過對5個誘變株的菌落特征、生長速率、大孢子千分率、分生孢子不同聚集方式及蟲草菌素含量等生物學特性比較,結果顯示,誘變最適時間為60s,且大孢子比例高、擬青霉型產(chǎn)孢結構比例大的菌株生物學特性較優(yōu)。

【Abstract】 Ultraviolet radiation to mutate Pm0217F were adopted,and five different strains were obtained at different times of UV mutagenesis.The colony morphology,growth rate,megaspore's permillage,conidiophore of different aggregation methods and content of cordycepin were compared.The results showed that the best time was 60 s,and the strain that had high proportion of megaspore and high proportion of Paecilomyces-type showed the best biological characters.
