A Gram-negative, non-spore-forming, rod-shaped bacterial strain, K106T, was isolated from wastewater collected from a textile dye works in Korea. Strain K106T grew optimally at pH 7.0–7.5 and 30–37 °C in the presence of 0–1.0 % (w/v) NaCl. A phylogenetic tree based on 16S rRNA gene sequences showed that strain K106T joined the type strain of Chelatococcus asaccharovorans with a bootstrap resampling value of 99.9 %. The predominant ubiquinone of strain K106T was Q-10. The fatty acid profile of strain K106T was similar to that of C. asaccharovorans DSM 6462T. Major polar lipids of strain K106T and C. asaccharovorans DSM 6462T were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, two aminolipids and two unidentified phospholipids. sym-Homospermidine, spermidine and putrescine were major polyamines. The DNA G+C content was 68.3 mol%. Strain K106T exhibited 16S rRNA gene sequence similarity of 96.6 % to the type strain of C. asaccharovorans. DNA–DNA relatedness data and differential phenotypic properties, particularly differences in cell morphology and the ability to utilize nitrilotriacetate, demonstrated that strain K106T can be differentiated from C. asaccharovorans. On the basis of phenotypic, phylogenetic and genetic data, strain K106T represents a novel species of the genus Chelatococcus, for which the name Chelatococcus daeguensis sp. nov. is proposed. The type strain is K106T (=KCTC 12979T =CCUG 54519T).
