Pedobacter aquicola sp nov., isolated from freshwater

초록

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 omega 6c and/or C-16:1 omega 7c). 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)).
