title: Rapidithrix thailandica gen. nov., sp. nov., a marine gliding bacterium isolated from samples collected from the Andaman sea, along the southern coastline of Thailand.
abstract: The taxonomic positions of three strains of marine gliding bacteria, TISTR 1736, TISTR 1741 and TISTR 1750(T), isolated from the southern coastline of Thailand were evaluated by using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the three isolates formed a distinct lineage within the family 'Flammeovirgaceae', phylum Bacteroidetes, and were related to the genus Flexithrix. The DNA G+C contents of the isolates were in the range 40-43 mol%. The major respiratory quinone was MK-7. The major cellular fatty acids were 16 : 1omega5c (cis-5-hexadecenoic acid) and 15 : 0 (pentadecanoic acid). The major hydroxyl fatty acids were 3-OH 17 : 0 (3-hydroxyheptadecanoic acid), 3-OH 15 : 0 (3-hydroxypentadecanoic acid) and 3-OH 16 : 0 (3-hydroxyhexadecanoic acid). On the basis of phenotypic, chemotaxonomic, genotypic and phylogenetic data, these marine bacteria are considered to represent a novel species of a new genus, for which the name Rapidithrix thailandica gen. nov., sp. nov. is proposed. The type strain of Rapidithrix thailandica is TISTR 1750(T) (=IAM 15448(T)).
