【摘要】 从我国传统糖化发酵剂中分离到产lovastatin的功能性红曲霉菌株,采用微波与离子束对该菌株进行了复合诱变选育工作,使其lovaststin的产量比照出发菌种提高了500%,培养条件优化后产量达到1.8mg/g,并对桔青霉素的含量进行了测定。更多还原

【Abstract】 A wide lovastatin-producing Monascus strain was isolated from Chinese traditional saccharifying starter which was widely used in food fermentation industry.A mutant of the Monascus strain was achieved by compound mutagenesis of microwave and ion-beam.The lovastatin yield of the mutant was raised to 500% compared with the wide Monascus strain.The lovastatin yield of the mutant was 1.8 mg/g after the optimization of fermentation conditions.The content of citrinin was also determined.更多还原
