Felfoldi et al. 2014.
Gram-negative rods, 0.4-0.7 x 0.7-1.8 μm. Motile.
Colonies on TSA are beige, circular and raised, with a diameter of 1-2 mm. Growth
occurs at pH 6-9 (optimum pH 6-7) and 0-5.0% NaCl (optimum 0-1.5%). Can grow at
4 ºC, not at 45 ºC, optimum 20-37 ºC. Aerobic.
Isolated on phenol-supplemented inorganic growth medium from a laboratory-scale wastewater purification system that treated coke
plant effluent.
Undetermined.
