| Popis: | A novel actinomycete, designated strain KK5PA1T, was isolated from a soil sample collected from Kuan Kreng peat swamp forest, Nakhon Si Thammarat Province, Thailand. The morphological, chemotaxonomic and phylogenetic characteristics were consistent with its classification in the genus Streptomyces . Strain KK5PA1T was most closely related to Streptomyces bryophytorum NEAU-HZ10T (98.0 %) and Streptomyces guanduensis 701T (97.6 %). The G+C content of the genomic DNA was 72.3 mol%. Digital DNA–DNA hybridization and average nucleotide identity values between the genome sequence of strain KK5PA1T and those of S. bryophytorum DSM 42138T(25.1 and 79.1 %) and S. guanduensis DSM 41944T(25.1 and 79.7%) were below the thresholds of 70 and 96 % for prokaryotic conspecific assignation. Chemotaxonomic data revealed that strain KK5PA1T possessed MK-9(H6) and MK-9(H8) as the predominant menaquinones. It contained ll -diaminopimelic acid as the diagnostic diamino acid and galactose, glucose, mannose and ribose as whole-cell sugars. The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol mannoside, two unidentified aminolipids, five unidentified phospholipids and an unidentified lipid. The predominant cellular fatty acids were iso-C16 : 0, anteiso-C15 : 0 and C16 : 0. On the basis of these genotypic and phenotypic data, it is proposed that strain KK5PA1T represents a novel species of the genus Streptomyces , for which the name Streptomyces acididurans sp. nov. is proposed. The type strain is strain KK5PA1T (=TBRC 13094T=NBRC 114802T). |
