Abstract

A Gram-reaction-negative, aerobic, non-spore forming, rod-shaped bacterium motile with a single polar flagellum, designated strain hydD622, was isolated from the sediment of a tidal flat at Asan Bay, Korea. Strain hydD622 exhibited an agarolytic activity. Comparison of 16S rRNA gene sequences revealed that strain hydD622 was closely related to KCTC 42116, KCTC 22256 and KCTC 32555 with similarities of 98.4, 98.0 and 96.5 %, respectively. Strain hydD622 was clustered distantly from the other genera in the family but formed a unique clade within the genus based on the 16S rRNA gene sequence. The DNA–DNA relatedness with KCTC 42116 and KCTC 22256 was 39.0 and 37.8 %, respectively. The major fatty acids (>10 %) were C,Cω6/Cω7 and Cω6/Cω7. The respiratory quinone was ubiquinone-8, and the polar lipid profile consisted of phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and an unidentified lipid. The DNA G+C content was 44 mol%. On the basis of physiological, chemotaxonomic and phylogenetic analyses, strain hydD622 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain of sp. nov. is hydD622 (=KCTC 32543=CGMCC 1.12692).
