Pedobacter insulae sp. nov., isolated from soil.
A Gram-negative, non-motile, rod-shaped bacterium, DS-139(T), was isolated from a soil sample collected from Dokdo, Korea, and subjected to a polyphasic taxonomic analysis. Strain DS-139(T) grew optimally at 25 degrees C and pH 6.5-7.5 in the presence of 0-0.5 % (w/v) NaCl. It contained MK-7 as the predominant menaquinone and iso-C(15 : 0), C(16 : 1)omega7c and/or iso-C(15 : 0) 2-OH and iso-C(17 : 0) 3-OH as the major fatty acids. The DNA G+C content was 39.4 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain DS-39(T) belongs to the genus Pedobacter in the family Sphingobacteriaceae. The similarity values between the 16S rRNA gene sequence of strain DS-139(T) and those of the type strains of recognized Pedobacter species, except Pedobacter saltans, were in the range 93.9-96.7 %. The differential phenotypic properties, together with the phylogenetic distinctiveness, were sufficient to assign strain DS-139(T) to a species that is separate from recognized Pedobacter species. On the basis of the phenotypic and phylogenetic data, therefore, strain DS-139(T) represents a novel species of the genus Pedobacter, for which the name Pedobacter insulae sp. nov. is proposed. The type strain is DS-139(T) (=KCTC 12820(T) =DSM 18684(T)).
