  • Title: Streptomyces seymenliensis sp. nov., isolated from soil.
    Author: Tatar D, Sahin N.
    Journal: Antonie Van Leeuwenhoek; 2015 Feb; 107(2):411-8. PubMed ID: 25424909.
    Abstract:
    A novel actinomycete, designated strain B1041(T), isolated from soil collected from the Tuz (Salt) Lake in the central Anatolia region, in Turkey, was characterised using a polyphasic taxonomic approach. The isolate was found to have chemical and morphological properties typical of the members of the genus Streptomyces and formed a distinct phyletic line in the 16S rRNA gene tree. Strain B1041(T) was found to be most closely related to Streptomyces plumbiresistens CCNWHX 13-160(T) (98.46 % sequence similarity), Streptomyces pseudovenezuelae NBRC 12904(T) (97.81 %), Streptomyces novaecaesareae NBRC 13368(T) (97.68 %), Streptomyces graminifolii JL-22(T) (97.60 %), Streptomyces phaeoluteigriseus NRRL ISP-5182(T) (97.58 %), Streptomyces ciscaucasicus NBRC 12872(T) (97.53 %) and Streptomyces pratensis ch24(T) (97.52 %). Sequence similarities with other strains of the genus Streptomyces were lower than 97.5 %. The cell wall of the novel strain was found to contain LL-diaminopimelic acid and the whole cell sugars were identified as galactose, glucose and ribose. The major cellular fatty acids were identified as anteiso C15:0 , iso C16:0 and anteiso C17:0. The predominant menaquinones found were found to be MK-9(H8) and MK-9(H6). The polar lipids detected were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, a phosphoglycolipid and two unknown phospholipids. The genomic DNA G+C content was determined to be 70.4 mol%. On the basis of the data from this polyphasic taxonomic study, strain B1041(T) can be considered to represent a novel species within the genus Streptomyces for which the name Streptomyces seymenliensis sp. nov. is proposed (type strain B1041(T) =KCTC 29245(T) = DSM 42117(T)).
