Pedobacter koreensis sp. nov., isolated from fresh water

Abstract

A motile, rod-shaped bacterium, designated strain WPCB189T, was isolated from fresh water collected from the Woopo wetland (Republic of Korea). The cells were found to be Gram-negative, aerobic and catalase- and oxidase-positive. A phylogenetic analysis based on 16S rRNA gene sequences showed that this isolate forms a lineage within the genus Pedobacter, showing sequence similarities of 89.7-96.4% with respect to recognized species of the genus, and represents a novel member of this genus. The major fatty acids were iso-C15:0 2-OH and/or C16:1ω7c (summed feature 3, 29.7%), iso-C15:0 (26.4%) and iso-C17:1 3-OH (10.1%). The DNA G+C content was 38.0 mol%. On the basis of data obtained from this polyphasic taxonomic study, strain WPCB189T represents a novel species of the genus Pedobacter, for which the name Pedobacter koreensis sp. nov. is proposed. The type strain is WPCB189T (=KCTC 12536T=NBRC 101153T).
