Abstract:
A marine bacterial strain, designated FR1050(T), 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 gamma-Proteobacteria. Sequence similarity between strain FR1050(T) 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 C(18 : 1)omega9c (39.0 %) and C(16 : 0) (18.1 %). The DNA G+C content was 44 mol%. The polyphasic data obtained showed that strain FR1050(T) 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 FR1050(T) (=KCTC 12277(T)=JCM 12486(T)).
