A chitosanase-producing bacterium strain is isolated from soil. It was identified as Penicillium sp. Its chitosanase yield was improved by UV irradiation. The chitosanase fermentation condition for the mutant strain was first optimized with Plackett-Burman design and then the influence of the culture temperature
the rotating speed of the rime
the component of the culture medium and the medium volume were studied to optimize the fermentation conditions. A maximum yield of 216.6 U/ml was obtained.
