abstract= A Gram-negative, facultatively anaerobic strain with slightly curved and straight rod-shaped cells, strain CL-GR58T, was isolated from coastal seawater (near Gori, Korea). Analyses of the 16S rRNA gene sequence revealed that strain CL-GR58T belonged to the family Rhodospirillaceae with Azospirillum lipoferum as its closest relative (gene sequence similarity of 90.9 %). Phylogenetic analyses of the 16S rRNA gene sequences showed that strain CL-GR58T was not associated with any known genera in the family Rhodospirillaceae. The novel strain grew in the presence of 1–10 % sea salts, optimally at 30–35 °C and pH 8. The major cellular fatty acids consisted of C18 : 1 ω7c (48.5 %), C16 : 0 (14.8 %), C17 : 0 (12.2 %), C19 : 0 cyclo ω8c (6.3 %) and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH, 6.0 %). Among the phylogenetically related genera, the fatty acid C17 : 0 was found only in strain CL-GR58T. The DNA G+C content of the novel strain was 68.0 mol%. According to phylogenetic analyses of the 16S rRNA gene sequence, fatty acid content and the physiological data, strain CL-GR58T represents a novel species in a new genus of the family Rhodospirillaceae, for which the name Thalassobaculum litoreum gen. nov., sp. nov. is proposed. The type strain of the type species is CL-GR58T (=KCCM 42674T=DSM 18839T).,
