Fluviicola taffensis gen. nov., sp nov., a novel freshwater bacterium of the family Cryomorphaceae in the phylum 'Bacteroidetes'

A novel, strictly aerobic, Gram-negative, yellow–orange-pigmented, motile, catalase-positive, oxidase-negative bacterium, RW262T, was isolated from water of the River Taff, Cardiff, UK, during January 2000. Phylogenetic analysis of the 16S rRNA gene indicated that strain RW262T was a member of the family Cryomorphaceae within the phylum ‘Bacteroidetes’. The DNA G+C content of strain RW262T was 37·2 mol%. The predominant fatty acid was the branched-chain saturated fatty acid i15 : 0 (44·2 %). On the basis of polyphasic analysis of phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics, it is proposed that this freshwater bacterium represents a novel genus and species within the family Cryomorphaceae, Fluviicola taffensis gen. nov., sp. nov. The type strain is RW262T (=NCIMB 13979T=DSM 16823T).
