title: [Isolation of a lipase-producing Pseudomonas strain and optimization of its fermentation conditions].
abstract: 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 treatment 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.
