Gram-negative rods, 0.3-0.6 x 0.7-2.5 μm.  Non-motile. Non-spore-forming.
Colonies on TSA are circular to slightly irregular, yellowish-white in colour and 1.0-2.0
mm in diameter after 3 days incubation at 37 ºC. Growth occurs at 15 and 46 ºC, but
not at 10 or 47 ºC. Growth occurs at pH 5.0 and 9.0, optimally at pH 7-8, but nnot at pH
44.5 or 9.5. Growth occurs in the presence of 0-5% (w/v) NaCl; optimally in the
presence of 0.5% (w/v) NaCl. No anaerobic growth occurs on TSA or on TSA
supplemented with nitrate.
Isolated from wastewater from a dye works at Daegu, Korea. Susceptible to tetracycline, chloramphenicol, gentamicin, kanamycin,
neomycin and polymyxin. Resistant to carbenicillin, ampicillin, cephalothin, lincomycin, novobiocin, oleandomycin, penicillin G and
streptomycin.
Undetermined.
