A non-motile, pink-pigmented bacterial strain designated IMCC25679 T , was isolated from freshwater Lake Chungju of Korea. Phylogenetic trees based on 16S rRNA gene sequences showed that the strain IMCC25679 T formed a lineage within the genus Pedobacter . The strain IMCC25679 T was closely related to Pedobacter daechungensis Dae 13 T (96.4% sequence similarity), Pedobacter rivuli HME8457 T (95.3%) and Pedobacter lentus DS-40 T (94.3%). The major fatty acids of IMCC- 25679 T were iso-C 15:0 , iso-C 16:0 and summed feature 3 (comprising C 16:1 ω 6 c and/or C 16:1 ω 7 c ). The major respiratory quinone was MK-7. The major polar lipids were phosphatidylethanolamine (PE), an unidentified sphingolipid (SL), an unidentified aminolipid (AL) and three unidentified polar lipids (PL). The DNA G + C content of IMCC25679 T was 32.2 mol%. Based on the evidence presented in this study, the strain IMCC25679 T represents a novel species within the genus Pedobacter , with the proposed name Pedobacter aquicola , sp. nov. The type strain is IMCC25679 T (= KACC 19486 T = NBRC113131 T ).
