flat, 2.0-4.0 mm in diameter (3 days at 30 ºC). Grows on marine agar and broth 2216E
Becton Dickinson. Is unable to grow in the absence of Na+. Grows in marine broth
with 2-6% NaCl (2-3 % NaCl optimum).
Anaerobic, temperature 4-41 ºC, (optimum 25-30 ºC), optimum pH 7.5-8.5 (can grow
at pH 5). Not bioluminescent.
Isolated from a tidal flat sediment at Saemankum, Korea. Not susceptible to Oleandomycin or Tetracycline.
