Streptomyces yunnanensis sp. nov., a mesophile from soils in Yunnan, China.
A strain was isolated from red soil from the suburb of Kunming in Yunnan, China, during the screening of agricultural antibiotics which prevented and cured wheat-stem rust. This isolate, designated YIM 41004T (= CGMCC 4.1004T = DSM 41793), was identified by a polyphasic approach. The test results suggested that this strain was clearly assigned to the genus Streptomyces and found to be marginally close to Williams cluster 32 based on the morphological and physiological data. The almost-complete 16S rRNA gene sequence of the strain was determined and compared with those of representative streptomycetes. The phylogenetic tree confirmed its membership in the genus Streptomyces and demonstrated that this strain represented a separate phyletic line in a clade encompassed by streptomycetes within cluster 32. Based on the polyphasic evidence, it is therefore proposed that strain YIM 41004T should be classified as Streptomyces yunnanensis sp. nov.
