Abstract

Two novel , designated strains YC419 and YC504, were isolated from a sediment sample collected from Lake Yeniçağa, Bolu Province, Turkey. Chemotaxonomic and morphological characteristics of isolates were found to be typical of members of the genus . Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain YC419 was most closely related to NBRC 13094 (99.0 %) and ‘’ NEAU-LA29 (98.6 %), and strain YC504 was to most closely related to NCCP-1331 (98.6 %) and IH32-1 (98.0 %). The cell walls of the two strains contained -diaminopimelic acid as the diagnostic diamino acid and the whole-cell hydrolysates were glucose, mannose and ribose. The predominant menaquinones were MK-9(H) and MK-9(H) in both strains. The major polar lipids of strain YC419 were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol, while strain YC504 had a similar profile but lacking diphosphatidylglycerol. The G+C contents of the genomic DNAs were 69.6 and 70.3 mol% for strains YC419 and YC504, respectively. The phenotypic and genotypic data indicated that these two strains were readily distinguished from one another and the type strains of the other species classified in the genus . Therefore, the strains are suggested to represent two novel species of the genus , for which the names sp. nov. and sp. nov. are proposed. The type strains are YC419 (=DSM 102299=KCTC 39757) and YC504 (=DSM 102300=KCTC 39756), respectively.
