Bacillus chondroitinus Nakamura 1987.
Gram-positive, motile rods, 0.5–1.0 x 3.0–5.0 μm. Produce ellipsoidal spores in
swollen sporangium.
Colonies are nonpigmented, translucent, smooth, 1-2 mm in diameter after 3 days at
28 ºC. Grow aerobically, but not anaerobically. Grow in 2% NaCl, rarely at 3% NaCl.
mesophilic, grow from  5-10 ºC to 35-40 ºC, optimum temperature 28-30 ºC. Can
grow at pH 5.7. Isolated in medium enriched with alginate.
Isolated from soil. Resistance to 0.001% lysozyme is usually negative.
Undetermined.
