Abstract
A marine bacterial strain, designated FR1050T, was isolated from a sediment sample of getbol (Korean tidal flat). Phylogenetic investigations based on 16S rRNA gene sequence analysis showed that the isolate formed a robust monophyletic clade with Hahella chejuensis within the γ-Proteobacteria. Sequence similarity between strain FR1050T and the type strain of Hahella chejuensis was 94·7 %. Cells were Gram-negative, aerobic, rod-shaped, motile and halophilic; optimum growth occurred at sea salt concentrations of 4–6 %. The major fatty acids were C18 : 1 ω9c (39·0 %) and C16 : 0 (18·1 %). The DNA G+C content was 44 mol%. The polyphasic data obtained showed that strain FR1050T is affiliated to the genus Hahella but represents a novel species for which the name Hahella ganghwensis sp. nov. is proposed. The type strain is FR1050T (=KCTC 12277T=JCM 12486T).
