Colonies on CB medium display a large clear zone around them, which is derived
from degradation of chitin. No diffusible pigments are produced. Grow well by using
chitin as the sole carbon, nitrogen and energy source. Aerobic and facultatively
anaerobic.  Growth occurs at 15-40 ºC. Grows at pH 7.0-11.0 and with 0-0.75% NaCl.
