Abstract

A new genus Streptoalloteichus is proposed in the family Actinoplanaceae to distinguish species of actinomycetes which form short or long spore-chains on aerial mycelium, bears oval sporangia with motile spores and has a characteristic cell-wall composition of strain C677-91 type. Strain C677-91 (ATCC 31217, FERM-P No. 4070) was named Streptoalloteichus hindustanus gen. nov. and sp. nov. The actinomycete strain C677-91 produces spore-chain clusters and sclerotia in the aerial mycelium which are morphologically similar to those found in some species of Streptomyces. The cultural characteristics of the strain on agar media also resemble those of Streptomyces species and the colonies have no distinct color. Strain C677-91 produces sporangia or sporangia-like vesicles which contain one to several spores in the vegetative mycelium. The sporangiospores possess a single long polar flagellum and are motile. The cell wall of strain C677-91 contains meso-alpha,epsilon-diaminopimelic acid, alanine, glutamic acid, galactose, mannose, rhamnose and glucosamine. Strain C677-91 has several important characteristics in common with Streptomyces tenebrarius including the production of nebramycin factors but the latter strain does not produce sporangia.

摘要

在游动放线菌科中提出了一个新属——链异壁放线菌属，以区分在气生菌丝体上形成短或长孢子链、带有具运动性孢子的椭圆形孢子囊且具有C677 - 91型菌株特征性细胞壁组成的放线菌物种。菌株C677 - 91（ATCC 31217，FERM - P No. 4070）被命名为印度链异壁放线菌，新属，新种。放线菌菌株C677 - 91在气生菌丝体中产生孢子链簇和菌核，其形态与某些链霉菌物种中发现的相似。该菌株在琼脂培养基上的培养特征也与链霉菌物种相似，菌落没有明显颜色。菌株C677 - 91在营养菌丝体中产生含有一至几个孢子的孢子囊或类孢子囊泡。孢子囊孢子具有一根单一的长极鞭毛且具运动性。菌株C677 - 91的细胞壁含有内消旋-α，ε-二氨基庚二酸、丙氨酸、谷氨酸、半乳糖、甘露糖、鼠李糖和氨基葡萄糖。菌株C677 - 91与黑暗链霉菌有几个重要的共同特征包，括产生暗霉素因子，但后一种菌株不产生孢子囊。
