A Gram-positive, aerobic, non-motile actinobacterium, designated strain 6014T, was isolated from a soil sample collected from Qinghai province, north-west China, and subjected to a polyphasic taxonomic study. The isolate formed elementary branching hyphae and abundant aerial mycelia with globose sporangia on ISP 4 and R2A media. Whole-cell hydrolysates of strain 6014T contained arabinose, galactose and ribose as diagnostic sugars and meso-diaminopimelic acid as the diagnostic diamino acid. The polar lipids consisted of phosphatidylmethylethanolamine, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, N-acetylglucosamine-containing phospholipids, two unknown phospholipids and an unknown glycolipid. The menaquinone system contained MK-9(H2) and MK-9(H4). The major fatty acids were C14 : 0, i-C15 : 0, C16 : 0 and 10-methyl-C16 : 1. The genomic DNA G+C content of the isolate was 69.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 6014T fell within the radius of the suborder Streptosporangineae, in which the strain formed a distinct lineage next to genera of the family Streptosporangiaceae. Based on data from this polyphasic study, strain 6014T can be readily distinguished from previously described organisms and represents a member of a novel species within a new genus in the suborder Streptosporangineae. The name Sinosporangium album gen. nov., sp. nov. is proposed with 6014T (=DSM 45181T =KCTC 19655T) as the type strain.
