title: Streptomyces roseoalbus sp. nov., an actinomycete isolated from soil in Yunnan, China.
abstract: An actinomycete strain was isolated from a soil sample collected from a secondary forest at Yongsheng of Yunnan province, China. The isolate, YIM 31634T, was identified by a polyphasic approach. The 16S rDNA sequence analysis showed that the strain YIM 31634T belongs to the genus Streptomyces, with closest similarity to Streptomyces olivochromogenes DSM 40451T (97.66% similarity). Sequence similarities between strain YIM 31634T and other Streptomyces species in the same subclade ranged from 97.59% (with Streptomyces resistomycificus DSM 40133T) to 97.22% (with Streptomyces mirabilis ATCC 27447T). Key phenotypic characteristics as well as chemotaxonomic features of the actinomyces were congruent with the description of the genus Streptomyces. On the basis of phenotypic and phylogenetic analyses, strain YIM31634T was recognized as a new species of the genus Streptomyces for which the name Streptomyces roseoalbus sp. nov. is proposed. The strain YIM 31634T has been deposited in the Chinese Center of Type Culture Collection as strain CCTCC M 203016T and in the Deutsche Sammlung von Mikroorganismen (DSM 41833T).
