Synonym:
Bacillus lautus  Batchelor 1919 ; Bacillus lautus Nakamura 1984. This species represents DNA hybridization group 9 of
Bacillus circulans sensu lato.
Gram-positive, motile rods, 0.5-1.0 x 4.0-7.0 µm, occurring singly and in pairs.
Produce subterminal, ellipsoidal spores in swollen sporangium.
Colonies are graysh/white, low, convex, circular to irregular, 1-2 mm in diameter after
2-3 days on nutrient agar at 30 ºC.  There is a tendency for motile colonies to spread
across the agar surface. Aerobic and anaerobic growth. Can grow at 5-10 to 45-50 ºC,
optimally at 28-30 ºC. Grow in 2 & 5% NaCl media.
Isolated from soil and human intestinal tract.
Undetermined.
