Twelve mutants were obtained from chlorpyrifos-degrading strain Cladosporium cladosporioides Hu-01 by UV-induced screening and their degradation capacities were determined by high performance liquid chromatography(HPLC).The degradation abilities of mutant strain Hu-01-4 and Hu-01-6 were higher than the original strain Hu-01.Furthermore,the mutant strain Hu-01-6 kept a good stability of degradation rate after 10 serial passages on the test-tube medium containing chlorpyrifos,increasing by 11.74% compared with the original strain.Moreover,both the growth and degradation ability of mutant strain Hu-01-6 were higher than original strain Hu-01 under the conditions of 28 ℃and pH 6.5.
