Abstract

Strain FYK2218 was isolated from a specimen of the chiton , which had been collected from a beach on the Boso peninsula in Japan. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the strain belonged to the phylum ‘’. The most closely related type strains to strain FYK2218 were TMBS4 (83.6 % 16S rRNA gene sequence similarity) and H-5 (83.6 %) in subdivision 8 of the ‘’. Cells of FYK2218 were motile, rod-shaped, Gram-negative, mesophilic and strictly aerobic. The G+C content of the strain was 56.7 mol%. The strain had isoprenoid quinones MK-6 and MK-7 as major components. Major fatty acids of the strain were iso-C, iso-C, C and C 3 (-5,8,11,14,17-eicosapentaenoic acid). From the taxonomic data obtained in this study, it is proposed that the new marine isolate be placed into a novel genus and species named gen. nov., sp. nov. within the new family, order and class fam. nov., ord. nov. and classis nov. The family fam. nov. is also described. The type strain of is FYK2218 (=NBRC 101209 =KCTC 12899).
