Pedobacter agri sp. nov., from soil

Abstract

A Gram-negative strain, PB92T, which belongs to the family Sphingobacteriaceae, was isolated from soil (Daejeon, Korea). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain PB92T was associated with the genus Pedobacter and was most closely related to the type strains Pedobacter sandarakinus DS-27T (97.7%), Pedobacter roseus CL-GP80T (97.5%) and Pedobacter suwonensis 15-52T (97.5%). The major cellular fatty acid components of strain PB92T were C16:1ω7c (21.4%), iso-C15:0 (30.8%), iso-C17:0 3-OH (9.3%) and iso-C15:0 2-OH (11.2%). The G+C content of the genomic DNA from strain PB92T was 41.4 mol%. Analysis of 16S rRNA gene sequences, as well as physiological and biochemical tests, indicated that strain PB92T could be differentiated genotypically and phenotypically from reference species of the genus Pedobacter. Strain PB92T (=KCTC 12511T=DSM 19486T) is proposed as the type strain of a novel species, Pedobacter agri sp. nov.
