Caenimicrobium [Cae.ni.mi.cro'bi.um, L. neut. n. caenum mud, referring to the isolation of the type strain from activated sludge; N.L. neut. n. microbium microbe (from Gr. adj. mikros small and Gr. n. bios life); N.L. neut. n. Caenimicrobium mud (‐inhabiting) microbe]. Proteobacteria / Betaproteobacteria / Burkholderiales / Alcaligenaceae / Caenimicrobium. Gram‐negative‐staining nonmotile short rods, forming beige colonies on nutrient medium. Mesophilic, aerobic, and catalase‐ and cytochrome c oxidase‐positive. Major polar lipids are phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, and an unidentified phospholipid, and major cellular fatty acids are C16:1 ω7c, C16:0, cyclo C17:0, and C18:1 ω7c. Ubiquinone 8 is the major respiratory quinone. The type and unique species is Caenimicrobium hargitense, represented by the type strain CGII‐59m2T isolated from activated sludge. Caenimicrobium hargitense strain CGII‐59m2T shares 16S rRNA gene sequence similarity >97% with members of the genera Bordetella, Candidimonas, Paracandidimonas, and Parapusillimonas. DNA G + C content (mol%): 62.3 (HPLC method). Type species: Caenimicrobium hargitense, Felföldi et al. 2017VP.
