auxotrophic

ADI is a potential cancer therapy agent for the treatment of arginine-auxotrophic tumors ( such as hepatocellular carcinomas and melanomas), and it widely exists in bacteria, achaea and some anaerobic eukarya.

ADI广泛存在于细菌、古细菌、厌氧真核生物中，它是一种治疗精氨酸缺陷型肿瘤（如肝细胞癌、黑素瘤）的药物。

Compared ethanol fermentation power of these 18 fusants with 23 fusants selected by auxotrophic marker, the results demonstrated that percentage of high ethanol-yielding strains in fusants population selected by RAPD marker was significantly high than fusants population selected by auxotrophic marker.

该18株融合子酒精发酵能力经与传统的用营养缺陷型标记筛选的23株融合子比较，表明用RAPD标记筛选到的融合子群体中，高产菌株所占的比例明显高于前者。

We obtained the auxotrophic mutantS of k ( lys, p) and Q ( arg-) by mutation with DES. The frequency of fusion is 1. 25 per 105 protoplast.

通过硫酸二乙酯（DES）诱变得到营养缺隐型菌株Q（arg－）和K（lys－，ρ－），其融合率为1.25×10－5。
