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).
从中国云南省永胜县次生林采集的土壤样品中分离出一株放线菌菌株。通过多相分类法对该分离株YIM 31634T进行了鉴定。16S rDNA序列分析表明，菌株YIM 31634T属于链霉菌属，与橄榄产色链霉菌DSM 40451T最为相似（相似性为97.66%）。菌株YIM 31634T与同一亚分支中其他链霉菌物种之间的序列相似性范围为97.59%（与抗霉菌链霉菌DSM 40133T）至97.22%（与奇异链霉菌ATCC 27447T）。该放线菌的关键表型特征以及化学分类特征与链霉菌属的描述一致。基于表型和系统发育分析，菌株YIM31634T被认定为链霉菌属的一个新物种，为此提出了玫瑰白链霉菌新种（Streptomyces roseoalbus sp. nov.）的名称。菌株YIM 31634T已作为菌株CCTCC M 203016T保藏于中国典型培养物保藏中心，并作为菌株DSM 41833T保藏于德国微生物保藏中心（Deutsche Sammlung von Mikroorganismen）。
