The isolate was strictly aerobic and non-motile. Growth was observed between 10 and 35 °C (optimum 30 °C) and between pH 6.0 and 9.0 (optimum pH 7.0–8.0). The predominant cellular fatty acids of strain EMB320T were C16 : 0, C18 : 1 ω7c and summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. Strain EMB320T contained ubiquinone-8 (Q-8) as the major respiratory quinone system and 2-hydroxyputrescine and putrescine as the major polyamines, which suggests that it belongs to the Betaproteobacteria. The G+C content of the genomic DNA was 62.7 mol%. Comparative 16S rRNA gene sequence analysis showed that strain EMB320T formed a phyletic lineage distinct from other genera within the family Comamonadaceae. On the basis of chemotaxonomic data and molecular properties, strain EMB320T represents a novel genus and species within the family Comamonadaceae, for which the name Caenimonas koreensis sp. nov. is proposed. The type strain of Caenimonas koreensis is EMB320T (=KCTC 12616T =DSM 17982T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.65416-0
