| 摘 要： | A lipase-producing bacterium strain was isolated from soil and was identified as Pseudomonas sp.. Its lipase yield was improved 2.25-fold by combined beatment of UV irradiation and NTG. The lipase fermentation condition for the mutant strain was optimized with Plackett-Burman design and Response Surface Analysis(RSA), and the formula of the optimum medium suitable for industrial scale fermentation was thereby established. A maximum yield of 87.5 U/ ml was obtained.
