Gram-positive, motile rods, producing oval spores in terminal, unswollen sporangia.
Colonies on PYES agar are 2-3 mm in diameter, slightly raised, irregular and
cream-coloured to beige. Older colonies are more translucent. Growth occurs at 4 and
28 ºC (no growth at 37 ºC), in the presence of 0, 1, 3 and 5% NaCl (w/v) but not at 7 or
10% NaCl (w/v). On buffered medium, growth is observed at pH 7 (weakly), 8 and 9.
On unbuffered medium, growth is observed at pH 7 (weakly), 8, 9, 10, 11 and 12 but
not at pH 6. Haemolysis is not produced. Aerobic.
