Streptomyces burgazadensis sp nov., isolated from soil

A novel actinobacterial strain, designated Z1R7(T), was isolated from a soil sample collected from Burgazada, in the Marmara Sea (Turkey), and the strain identity was determined using a polyphasic taxonomic approach. The organism had chemotaxonomic and morphological properties consistent with its classification in the genus Streptomyces and it formed a distinct phyletic line in the 16S rRNA gene tree, together with the type strains Streptomyces specialis GW41-1564(T) (95.76 %), Streptomyces mayteni YIM 60475(T) (95.64%), Streptomyces hainanensis YIM 47672(T) (95.53 %), Streptomyces hoynatensis S1412(T) (95.29 %), Streptomyces avicenniae MCCC 1A01535T (94.74%), Streptomyces sedi YIM 65188(T) (94.59 %) and Streptomyces zhaozhouensis NEAU-LZS-5(T) (94.68 %). Chomotaxonomic data revealed that strain Z1R7(T) possesed MK-9 (H-8) as the predominant menaquinone, LLdiaminopimelic acid as the diagnostic diamino acid, and galactose, glucose and ribose as whole cell sugars. Diphosphatidylglycerol, phoshphatidylethanolamine and phosphatidylinositol were the predominant polar lipids; iso-C-16:0, anteiso-C-17:0 and anteiso-C-15:0 were the major fatty acids, and the genomic DNA G+C content was 69.4 mol%. On the basis of these genotypic and phenotypic data, it is proposed that isolate Z1R7(T) (=KCTC 29434(T)=DSM 42126(T)) should be classified in the genus Streptomyces as Streptomyces burgazadensis sp. nov.
