A non-motile, pink-pigmented bacterial strain designated IMCC25679, was isolated from freshwater Lake Chungju of Korea. Phylogenetic trees based on 16S rRNA gene sequences showed that the strain IMCC25679 formed a lineage within the genus Pedobacter. The strain IMCC25679 was closely related to Pedobacter daechungensis Dae 13 (96.4% sequence similarity), Pedobacter rivuli HME8457 (95.3%) and Pedobacter lentus DS-40 (94.3%). The major fatty acids of IMCC- 25679 were iso-C, iso-C and summed feature 3 (comprising Cω6c and/or Cω7c). 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 was 32.2 mol%. Based on the evidence presented in this study, the strain IMCC25679 represents a novel species within the genus Pedobacter, with the proposed name Pedobacter aquicola, sp. nov. The type strain is IMCC25679 (= KACC 19486 = NBRC113131).
一株非运动、粉红色着色的细菌菌株被命名为 IMCC25679，从韩国忠州淡水湖分离得到。基于 16S rRNA 基因序列的系统发育树表明，菌株 IMCC25679 形成了 Pedobacter 属内的一个分支。菌株 IMCC25679 与 Pedobacter daechungensis Dae 13（96.4%序列相似性）、Pedobacter rivuli HME8457（95.3%）和 Pedobacter lentus DS-40（94.3%）最为密切相关。IMCC-25679 的主要脂肪酸为 iso-C、iso-C 和总和特征 3（包含 Cω6c 和/或 Cω7c）。主要呼吸醌为 MK-7。主要极性脂为磷脂酰乙醇胺（PE）、一种未鉴定的神经酰胺（SL）、一种未鉴定的胺脂（AL）和三种未鉴定的极性脂（PL）。IMCC25679 的 DNA G+C 含量为 32.2mol%。基于本研究提供的证据，菌株 IMCC25679 代表了 Pedobacter 属内的一个新种，命名为 Pedobacter aquicola，sp. nov.。模式菌株为 IMCC25679（=KACC 19486=NBRC 113131）。
