Abstract

Two actinomycete strains, DF-28 and DF-32T, were isolated from soil samples collected in a deciduous dipterocarp forest in Thailand. They produced longitudinally paired spores on the tips of short sporophores alternately branched from aerial hyphae, and the chemotaxonomic properties of the isolates were the same as those of members of the family Streptosporangiaceae. These phenotypic properties, together with the results of a phylogenetic analysis based on 16S rRNA gene sequences, indicated that these isolates should be assigned to the genus Microbispora. The two isolates showed more than 93% DNA relatedness to each other, but their relatedness to any previously described species of the genus Microbispora was only 45% or less. They were distinguishable from previously described Microbispora spp. by a combination of physiological and biochemical properties. Therefore, a new species is proposed for these strains, under the name Microbispora corallina sp. nov. The type strain is strain DF-32T (= JCM 10267T).

从泰国土壤中分离的小孢子虫属一新种。

从泰国落叶龙果林土壤样品中分离到两株放线菌DF-28和DF-32T。它们在短孢子体的顶端产生纵向配对的孢子，孢子体由气生菌丝交替分叉，分离株的化学分类特性与链孢菌科成员相同。这些表型特征以及基于16S rRNA基因序列的系统发育分析结果表明，这些分离物应归属于微双孢菌属。这两个分离株的DNA亲缘度超过93%，但它们与任何先前描述的Microbispora属物种的亲缘度仅为45%或更低。通过生理和生化特性的结合，可以将它们与先前描述的微双孢菌区分开来。因此，建议将这些菌株命名为Microbispora corallina sp. nov.，类型菌株为菌株DF-32T (= JCM 10267T)。
