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, RW262(T), was isolated from water of the River Taff, Cardiff, UK, during January 2000. Phylogenetic analysis of the 16S rRNA gene indicated that strain RW262(T) was a member of the family Cryomorphaceae within the phylum 'Bacteroidetes'. The DNA G+C content of strain RW262(T) 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 RW262(T) (=NCIMB 13979(T)=DSM 16823(T)).
