Species description is based on a single isolate.
Gram-negative rods, 0.4-0.6 x 2.0-3.0 μm. Non-motile by flagella, motile by gliding.
Poly-beta-hydroxybutyrate granules are not accumulated.
Colonies on R2A are green pigmented, convex, mucoid, round and 1-2 mm in
diameter after 2 days at 30 ºC. Good growth occurs on blood and R2A agar. No
growth on MacConkey, nutrient, marine and TSA agars. Flexirubin-type pigments are
not produced. Green pigment produced. Growth occurs in the presence of 0-3.0 %
(w/v) NaCl (optimum; 0.5 %), at pH 5–10 (optimum; pH 6) and at 20-37 ºC (optimum;
30 ºC).
Isolated from a mesotrophic artificial lake in Korea. Susceptible to gentamicin, rifampicin, tetracycline, streptomycin, vancomycin and
kanamycin. Resistant to ampicillin, chloramphenicol, erythromycin and penicillin G.
Undetermined.
