Solitalea koreensis gen. nov., sp nov and the reclassification of [Flexibacter] canadensis as Solitalea canadensis comb. nov.

A Gram-negative, rod-shaped, non-spore-forming bacterium, designated strain R2A36-4(T), was isolated from greenhouse soil and subjected to a polyphasic taxonomic analysis. 16S rRNA gene sequence analysis revealed that the strain represented a novel member of the family Sphingobacteriaceae. Its nearest phylogenetic neighbour was the type strain of [Flexibacter] canadensis CIP 104802(T) (93.2 % 16S rRNA gene sequence similarity). Strain R2A36-4(T) and [F] canadensis CIP 104802(T) fell in a distinct cluster within the family Sphingobacteriaceae. Strain R2A36-4(T) contained MK-7 as the predominant quinone. Strain R2A36-4(T) and [F] canadensis CIP 104802(T) had iso-C-15 : 0, iso-C-17 : 0 3-OH, summed feature 3 and C-15 : 1 omega 6c as the major fatty acids. Strain R2A36-4(T) could be distinguished from [F] canadensis on the basis of several physiological properties and fatty acid compositions. Based on phenotypic characterization and 16S rRNA gene sequence analysis, strain R2A36-4(T) represents a novel species within a new genus, for which the name Solitalea koreensis gen. nov., sp. nov. is proposed. The type strain of Solitalea koreensis is strain R2A36-4T (=KACC 12953(T) =DSM 21342(T)). It is also proposed that [F] canadensis be transferred to this genus as Solitalea canadensis comb. nov. (type strain UASM 9D(T) =ATCC 29591(T) CIP 104802(T) =DSM 3403(T) =NBRC 15130(T) =JCM 21819(T) =KACC 13276(T) =LMG 8368(T)).
