Diaphorobacter [Di.a.pho.ro.bac'ter. Gr. masc. adj. diaphoros different, profitable; N.L. masc. n. bacter rod; N.L. masc. n. Diaphorobacter distinguished and profitable rod, referring to usefulness in nitrogen removal].Proteobacteria / Betaproteobacteria / Burkholderiales / Comamonadaceae / Diaphorobacter Rods, non‐spore‐forming, Gram‐stain‐negative. Motile with a single polar flagellum or nonmotile. Aerobic or facultative aerobic. Mesophilic with optimum growth conditions at a temperature around 28°C and pH 7. No special growth requirements. Catalase‐positive. Cytochrome c oxidase test varies among species. Chemoorganotrophic. Denitrifying or nitrate reduction. No indole production or glucose fermentation. Some members have the capacity to degrade poly(3‐hydroxybutyrate) (PHB) and poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV). The major respiratory quinone is ubiquinone 8, and the major fatty acids are C 16:0 , summed feature 3 (C 16:1 ω7c and/or iso‐C 15:0 2‐OH), and C 18:1 ω7c , and the predominant hydroxy fatty acid is C 10:0 3‐OH. DNA G + C content (mol%): 62.9–66.8. Type species: Diaphorobacter nitroreducens Khan and Hiraishi 2002, VL92.
