Streptomyces boncukensissp. nov., isolated from saltern soil

Abstract

A novel Gram-stain positive, aerobic, non-motile Actinobacterium, designated strain SB3404(T), was isolated from saltern soil collected from Boncuk Saltern, Sungurlu-corum, Turkey, and subjected to a polyphasic taxonomic approach. The organism has shown to have phylogenetic, chemotaxonomic, cultural and morphological properties consistent with its classification in the genusStreptomyces. 16S rRNA gene sequence analysis of strain SB3404(T)showed that it is closely related toStreptomyces albusNBRC 13014(T)(97.2% sequence similarity),Streptomyces xishensisYIM M 10378(T)(96.7%) andStreptomyces abyssalisYIM M 10400(T)(96.5%). The cell wall of the strain containedLL-diaminopimelic acid and the cell-wall sugars were glucose, mannose and ribose. The predominant menaquinones were identified as MK-9(H-8) and MK-9(H-6). The major cellular fatty acids were found to beiso-C-16:0,anteiso-C(17:0)andanteiso-C-15:0. Consequently, strain SB3404(T)is considered to represent a novel species in the genusStreptomyces, for which the nameStreptomyces boncukensissp. nov. is proposed. The type strain is SB3404(T)(= KCTC 49371(T) = JCM 34018(T)).
