Abstract

Three Gram-negative, stalked, motile bacteria, designated 0C-2-2, 0C-17 and LNM-3, were isolated from the red alga . 16S rRNA gene sequence analysis revealed that the three novel strains belonged to the family , and were closely related to G5 (96.5 % 16S rRNA gene sequence similarity) and 26III/A02/215 (94.3 %). The DNA G+C contents of the novel isolates (58.5–60.2 mol%) were clearly distinguished from those of G5 (47.1 mol%) and DSM 19091 (47.9 mol%). The G+C content of G5 obtained in this study was quite different from a previous report (63.6 mol%). DNA–DNA hybridization experiments showed that the novel strains constituted a single species. Eleven phenotypic features of the three isolates differed from those of both related genera. The predominant respiratory quinone was ubiquinone-10 and the major fatty acid was Cω7. On the basis of this polyphasic taxonomic analysis, the novel strains represent a novel genus and species, for which the name gen. nov., sp. nov. is proposed. The type strain of is 0C-2-2 ( = LMG 26424  = NBRC 108216).
