Streptomyces boluensis sp. nov., isolated from lake sediment.

A novel Gram-stain positive, aerobic, non-motile actinobacterium, designated strain YC537T, was isolated from lake sediment collected from Yenicaga Lake, Bolu, Turkey, and subjected to a polyphasic taxonomic approach. The organism had phylogenetic, chemotaxonomic, cultural and morphological properties consistent with its classification in the genus Streptomyces. 16S rRNA gene sequence analysis of strain YC537T showed that it is closely related to the type strain of Streptomyces ziwulingensis F22T (97.9% sequence similarity), Streptomyces tauricus JCM 4837 T (97.7%) and Streptomyces beijiangensis NBRC 100044 T (97.6%). The cell wall of the strain contained LL-diaminopimelic acid and the cell-wall sugars were glucose, galactose and ribose. The major phospholipids of strain YC537T were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol. The predominant menaquinones were identified as MK-9(H6) and MK-9(H8). The major cellular fatty acids were iso-C16:0, iso-C14:0, anteiso-C15:0 and iso-C15:0. Consequently, strain YC537T is considered to represent a novel species in the genus Streptomyces, for which the name Streptomyces boluensis sp. nov. is proposed. The type strain is YC537T (= KCTC 39750 T = DSM 102303 T).
