Strain $HME6451^T$ was isolated from Lake Soyang in Korea. Phylogenetic tree based on 16S rRNA gene sequence showed that strain $HME6451^T$ formed a lineage within the genus Pedobacter. The strain $HME6451^T$ was closely related to Pedobacter daechungensis (95.4% sequence similarity), Pedobacter lentus (94.4%), and Pedobacter glucosidilyticus (93.8%). And strain $HME6451^T$ was a Gram-staining-negative, short rodshaped, strictly aerobic bacterium. The major fatty acids were iso-$C_{15:0}$ (41.2%), summed feature 3 (comprising $C_{16:1}$ ${omega}7c$ and/or$C_{16:1}$ ${omega}6c$; 23.1%), and iso-$C_{17:0}$-3OH (10.1%). The polar lipids of $HME6451^T$ were consisted of one phosphatidylethanolamine, one unidentified aminolipid, one unidentified phospholipid and four unidentified polar lipids. The DNA G+C content was 36.0 mol%. On the basis of the evidence presented in this study, strain $HME6451^T$ represent a novel species of the genus Pedobacter, for which the name Pedobacter soyangensis sp. nov., is proposed the type strain $HME6451^T$ (=KCTC $23467^T$ =CECT $7865^T$).
