【摘要】 在寻找抗肿瘤抗菌素过程中,从西双版纳土壤分离到一株放线菌74-3527,经鉴定为一链霉菌新种,其代谢产物经光谱分析及核磁共振谱鉴别,与链黑菌素基本一致,故定名为链黑菌素链毒菌 Streptomyces streptonigrinus n.sp.Yan et al.,1977.本文报道这个新种的形态、培养特征、生理生化特性和与相近已知种的比较。更多还原

【Abstract】 In the course of screening newantitumor antibiotics,a species ofStreptomyces designated as No.74-3527was isolated from a Sishuangbenna soilsample.According to the UV,IR andNMR spectrum,this strain produces anantitumor antibiotic which is identicalto Streptonigrin formed by Streptomycesflocculus.Taxonomic studies show thatthe strain No.74-3527 is a new speciesamong the Streptomyces cinerogriseusgroup and was named Streptomycesstreptonigrinus n.sp.Yan et al.1977.更多还原
