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 1A01535^T (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 (H₈) as the predominant menaquinone, ll-diaminopimelic 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.
