    Saccharopolyspora hattusasensis sp nov., isolated from soil
    (Springer, 2017) Veyisoglu, Aysel; Saygin, Hayrettin; Tatar, Demet; Bektas, Kadriye Inan; Sahin, Nevzat
    A Saccharopolyspora strain, designated CR3506(T), isolated from a soil sample collected from Sungurlu, Corum, Turkey, was examinated using a polyphasic approach. Phylogenetic analysis based on an almost-complete 16S rRNA gene sequence analysis showed that the strain is closely related to the type strains of Saccharopolyspora spinosa NRRL 18395(T) (99.1%), Saccharopolyspora phatthalungensis NRRL B-24798(T) (98.4%) and Saccharopolyspora shandongensis 88(T) (98.1%); low levels of DNA-DNA relatedness were found between the isolate and S. spinosa and S. phatthalungensis (< 50%). Strain CR3506(T) was found to have chemotaxonomic and phylogenetic properties consistent with its classification in the genus Saccharopolyspora. The strain contained meso-diaminopimelic acid as the diagnostic diamino acid. Whole-cell hydrolysates contained arabinose and galactose. The polar lipids were identified as phosphatidylmethylethanolamine, phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol and phosphatidylinositol. The predominant menaquinones (> 10%) were MK-9(H-4) and MK-8(H-4). Major fatty acids were (> 10%) iso-C-16:0, C(15:0)3OH, C-18:0 and iso-C-15:0. Further, the morphological, physiological and biochemical characteristics of strain CR3506(T) are distinct from S. spinosa and other species of the genus Saccharopolyspora with which this strain has high 16S rRNA gene sequence similarity (98.0-98.5%). Strain CR3506(T) has antimicrobial activity against Bacillus subtilis NRRL B-209, Citrobacter freundi NRRL B-2643 and Staphylococcus aureus ATCC 29213. Consequently, it is proposed that strain CR3506(T) represents a novel Saccharopolyspora species for which the name Saccharopolyspora hattusasensis sp. nov. is proposed. The type strain is CR3506(T) (=KCTC 29104(T) = DSM 45715(T)).

    Streptomyces ovatisporus sp nov., isolated from deep marine sediment
    (Microbiology Soc, 2016) Veyisoglu, Aysel; Cetin, Demet; Bektas, Kadriye Inan; Guven, Kiymet; Sahin, Nevzat
    The taxonomic position of a Gram-staining-positive strain, designated strain S4702(T) was isolated from a marine sediment collected from the southern Black Sea coast, Turkey, determined using a polyphasic approach. The isolate was found to have chemotaxonomic, morphological and phylogenetic properties consistent with its classification as representing a member of the genus Streptomyces and formed a distinct phyletic line in the 16S rRNA gene tree. S4702(T) was found to be most closely related to the type strains of Streptomyces marinus (DSM 41968(T); 97.8% sequence similarity) and Streptomyces abyssalis (YIM M 10400(T); 97.6 %). 16S rRNA gene sequence similarities with other members of the genus Streptomyces were lower than 97.5 %. DNA-DNA relatedness of S4702 T and the most closely related strain S. marinus DSM 41968 T was 21.0 %. The G+ C content of the genomic DNA was 72.5 mol%. The cell wall of the strain contained L, L-diaminopimelic acid and the cell-wall sugars were glucose and ribose. The major cellular fatty acids were identified as anteiso-C-15 : 0, iso-C-16 : 0, anteiso-C-17 : 0 and iso-C-15 : 0. The predominant menaquinone was MK-9(H8). The polar lipid profile of S4702(T) consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannoside. S4702(T) could be distinguished from its closest phylogenetic neighbours using a combination of chemotaxonomic, morphological and physiological properties. Consequently, it is proposed that S4702(T) represents a novel species of the genus Streptomyces, for which the name Streptomyces ovatisporus sp. nov. is proposed. The type strain is S4702 T (DSM 42103(T) = KCTC 29206(T) = CGMCC 4.7357(T)).
