Gram-positive rods, 0.5-0.7 x 1.5-3 µm, occurring in large chains. Central ellipsoidal
endospores are observed in swollen sporangia and are 1.0 x 1.5-1.7 µm.

Colonies on MA are light yellow and 2-5 mm in diameter after 2 days growth at 37 ºC;
they are low, convex, circular and slightly irregular. Optimal growth temperature
is 30-37 ºC, maximum 45 ºC. Minimum pH is 5.0-5.5, optimum pH is 7-8, maximum
pH is 9. Halotolerant, growing in NaCl concentration from 0.5 to 10%.
