【摘要】 对保藏的红霉素链霉菌AS4.894、AS4.198的化学分类研究表明,它们的胞壁类型为IV/A型,不属于胞壁为Ⅱ型的链霉菌属。菌株AS4.198与已由Labeda(1987)转入糖多孢菌属(Saccharopolyspora),定名为Saccharopolyspora erythreus的菌株相似;菌株AS4.894虽然胞壁型与糖多孢菌相似,但磷酸类脂为PⅡ型,应转入拟无枝菌酸菌属(Amycolatopsis Lechevalier,1986)。通过与红霉素糖多孢菌(Saccharopolyspora erythreus)和白色拟无枝菌酸菌(Amycolatopsis alba,A83850~T)进行比较,菌株AS4.894的生长pH范围广泛,耐盐和耐50℃高温,DNA G+C mol％高,区别于拟无枝菌酸菌属中的任何已知种,而建议命名为新种——红霉素拟无枝菌酸菌(Amycolatopsis erythreus comb.nov.)。更多还原

【Abstract】 Chemotaxonomic analysis of cells wall of Streptomyces erythreus AS 4.894 and AS 4.198 revealed that these two strains are not representatives of the genus Streptomyces because the cell walls are type IV. The strain AS 4.198 belongs to species of Saccharopolyspora erythreus (Labeda, 1987). The phospholipid pattern of strain AS 4.894 was type PII, which defers from that of Saccharopolyspora. So, we propose that the strain AS 4.894 be transferred to the genus Amycolatopsis as the type strain of a new species, Amycolatopsis erythreus comb. nov.更多还原
