Nodasaka and Nakajima 2005.
Gram positive, straight rods, 0.7-0.9 x 1.1-4.4 µm. Produce terminal, ellipsoidal
endospores in unswollen sporangia. Nonmotile.
Colonies are white, circular when grown on PYA medium. Moderately halophilic and
facultatively alkaliphilic. Grow at pH 7-10 (optimum), in 5-20% NaCl media (optimum
7%) and at 13-41 ºC (optimum 30 ºC). NaCl is required for good growth; weak growth
at 0-3% NaCl. Aerobic; no anaerobic growth.
Isolated from soil, Oshyamanbe, Oshima, Hokkaido, Japan.
Undetermined.
