| Abstract: | A Chitosanase Producing Bacteria Yg was isolated from soil. Ameliorated the strain Yg with mutagenizing by UV and changing its＇ habitat. Four strains which had divers chitosanase-producing abilities were obtained. The chitosanase-producing ability of the first, the second and the forth number strain was four times to the original one. |
