Abstract

A novel bacterial strain, designated hydD52, was isolated from a sample of tidal flat sediment of the Yellow Sea in the Republic of Korea. The cells were motile, rod-shaped and Gram-stain-negative. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that strain hydD52 was a member of the genus and most closely related to DSM 16472 (98.0 %), HEL-45 (97.8 %) and DSM 28223 (97.6 %). The major fatty acids (>5 %) of hydD52 were C 7/C 6, C, Cω7 11-methyl and C 8. The respiratory quinone of strain hydD52 was ubiquinone-10. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine and an unidentified amino lipid. The G+C content of this strain was 64.0 mol%. The DNA–DNA relatedness values of hydD52 with the type strains of , and were 18.8, 13.1 and 15.7 %, respectively. Based on the results of morphological, physiological and chemotaxonomic characterization, DNA–DNA hybridization relatedness, and 16S rRNA genes analysis, we concluded that strain hydD52 represents a novel species, for which the name sp. nov. is proposed. The type strain is hydD52 (=KCTC 32982=TISTR 2562).
