A novel actinomycete, designated strain HC44T, was isolated from a soil sample collected from Hacibektaş, Turkey, and characterized using a polyphasic approach. The strain had morphological characteristics and chemotaxonomic properties identical to those of members of the genus Streptomyces . Phylogenetic analyses based on 16S rRNA gene sequence comparisons revealed that HC44T clustered with members of the genus Streptomyces and the highest 16S rRNA gene sequence similarity values were obtained with Streptomyces vastus NBRC 13094T (97.6 %) and Streptomyces kalpinensis TRM 46509T (96.9 %). Multi-locus sequence analysis (MLSA) based on five housekeeping genes (atpD, gyrB, recA, rpoB and trpB) showed that the MLSA evolutionary distance value was 0.043 between strain HC44T and S. vastus NBRC 13094T. Whole-cell hydrolysates contained ll-diaminopimelic acid, glucose, mannose and ribose. The predominant menaquinones were MK-9(H6) and MK-9(H8). The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. The DNA G+C content of the draft genome sequence, consisting of 11.2 Mbp, was 69.8 mol%. On the basis of polyphasic taxonomic evidence, strain HC44T represents a novel species of the genus Streptomyces , for which the name Streptomyces scabichelini sp. nov. is proposed. The type strain is HC44T (=DSM 106874T=KCTC 39872T).

An actinobacterium, designated 14C53T, was isolated from a soil sample on basaltic material from Samsun, Turkey. The growth ranges for NaCl concentration and pH of strain 14C53T were quite limited and the growth temperature range of the strain was 20–37 °C, with an optimum at 28 °C. Phylogenetic analysis of 16S rRNA gene sequences revealed that strain 14C53T was most closely related to Actinomadura geliboluensis A8036T (98.5 % similarity value), but in the phylogenetic tree, it formed a clade with Actinomadura alkaliterrae D310AT. The genome tree revealed a close relationship between the strain and Actinomadura pelletieri DSM 43383T. However, the digital DNA–DNA hybridization and average nucleotide identity values between strain 14C53T with Actinomadura geliboluensis A8036T and Actinomadura pelletieri DSM 43383T were 28.6–30.2 % and 84.3–85.5 %, respectively, and comparative analyses based on the genome sequences demonstrated that it represents a novel species of the genus Actinomadura . The genome size of strain 14C53T was approximately 9.0 Mb and the genomic DNA G+C content of the strain was 71.3 mol%. The major cellular fatty acids of strain 14C53T were C16 : 0 and iso-C16 : 0. Strain 14C53T contained meso-diaminopimelic acid as the diamino acid in the cell-wall peptidoglycan. The predominant menaquinones were MK-9(H8) and MK-9(H6). Based on evidence collected from the phenotypic, genotypic and phylogenetic analyses, a novel species Actinomadura soli sp. nov. is proposed, with 14C53T (=DSM 104447T=KCTC 39878T) as the type strain.

An Amycolatopsis strain, designated AG28, isolated from a soil sample collected from Acıgöl, Kapadokya, Turkey, was examined using a polyphasic taxonomic approach. Phylogenetic analysis based on an almost-complete 16S rRNA gene sequence showed that the strain is closely related to the type strains of Amycolatopsis deserti GY024 (97.1%), Amycolatopsis taiwanensis 0345 M-7 (96.9%) and Amycolatopsis pigmentata TT00-43 (96.9%). Strain AG28 was found to have chemotaxonomic and phylogenetic properties consistent with its classification in the genus Amycolatopsis. The strain was found to contain meso-diaminopimelic acid as the diagnostic diamino acid. The whole cell sugars identified were rhamnose, ribose, arabinose and galactose. The polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylinositol. The predominant menaquinone was identified as MK-9(H). Major fatty acids (> 10%) were identified as iso-C, iso-C and iso-C 2OH. Consequently, on the basis of the data from this polyphasic study, it is proposed that strain AG28 represents a novel Amycolatopsis species for which the name Amycolatopsis cappadoca sp. nov. is proposed. The type strain is AG28 (= KCTC 39884 = DSM 104280).
