title: Salinirepens amamiensis gen. nov., sp. nov., a member of the family Cryomorphaceae isolated from seawater, and emended descriptions of the genera Fluviicola and Wandonia.
abstract: The taxonomic position of bacterial strain AM11-6(T), isolated from seawater in Japan, was determined by using a polyphasic taxonomic approach. The strain was a strictly aerobic and Gram-staining-negative slender rod, motile by gliding. The major respiratory quinone was menaquinone-6 and the predominant cellular fatty acids were iso-C(15 : 0), iso-C(17 : 0) 3-OH, C(14 : 0) and iso-C(15 : 1) G. The polar lipid pattern indicated the presence of an unidentified phospholipid, several glycolipids and an unidentified polar lipid. The G+C content of the genomic DNA was 36.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain AM11-6(T) clustered with members of the genera Wandonia and Fluviicola in the family Cryomorphaceae of the phylum Bacteroidetes. The strain required NaCl and MgCl(2) for growth and could be differentiated from members of other genera in the family Cryomorphaceae by fatty acid composition and other phenotypic characters. On the basis of these results, we describe the novel genus and species, Salinirepens amamiensis gen. nov., sp. nov. The type strain of Salinirepens amamiensis is AM11-6(T) (= NBRC 101268(T) = NCIMB 14607(T)). Emended descriptions of the genera Fluviicola and Wandonia are also proposed.
