摘  要:
不同诱变剂及剂量处理古尼拟青霉CGAC5-19的分生孢子后,采用4种方法富集营养缺陷型。研究结果发现限量补给法是富集古尼拟青霉营养缺陷型的有效方法,由该法富集到5株营养缺陷型和几株形态、生理学上的变异株。对出发菌株CGAC5-19和5株营养缺陷型的某些生物学特征进行了测定和比较。本文还讨论了几种方法富集古尼拟青霉营养营养缺陷型的可行性。

摘  要:
The conidia of Paecilomyces gunnii CGAC5-19 were treated with different mutagenic agents under defferent dosages, and several methods were used for enrichment auxotroph. The results showed the limited enrichment method was the most effective method, and five strains of auxotroph, several morphological and physiological mutants were obtained by the method. Some biological charaterization were comparised among Paecilomyces gunnii CGAC5-19 and five auxotrophs. The results of different enrichment methods were discussed also.
