Pedobacter sandarakinus sp. nov., isolated from soil

A Gram-negative, non-motile, rod-shaped bacterial strain, designated DS-27^T, was isolated from a soil sample, and its taxonomic position was investigated by using a polyphasic approach. The organism grew optimally at 30 °C and in the presence of 0-0.5 % (w/v) NaCl. Strain DS-27^T contained MK-7 as the predominant menaquinone and iso-C_15:0, C_16:1 ω7c 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 39.7 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain DS-27^T is most closely related to the genus Pedobacter of the family Sphingobacteriaceae. Similarity values between the 16S rRNA gene sequences of strain DS-27^T and the type strains of recognized Pedobacter species ranged from 90.6 to 95.5 %. Differential phenotypic properties, together with the phylogenetic distinctiveness, were sufficient to categorize strain DS-27^T as representing a species that is separate from recognized Pedobacter species. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain DS-27^T (=KCTC 12559^T=CIP 108922^T) was classified in the genus Pedobacter as a member of a novel species, for which the name Pedobacter sandarakinus sp. nov. is proposed.
