Rods of 0.5-0.6/2.0-5.0 µm, subterminal, ellipsoidal endospores in swollen sporangia.
Colonies are adherent, white, rhizoid with filamentous margins. Aerobic growth.
Growth occurs at 10-45 ºC. Strictly alkaliphilic organisms; growth is observed at pH
7.0; optimal growth is observed at pH 10.0 or higher. Require NaCl for growth (2-16%
NaCl tolerance).
Isolated from soil.

Positive results for nitrate reduction, hydrolysis of: gelatin, casein, starch, cellulose,
xylan & Tween 40. Can utilize L-arabinose, galactose, mannose, N-acetylglucosamine
& 2-ketogluconate.
Negative results for deamination of phenylalanine, hydrolysis of hippurate, Tween 20
