Combined Mutation of Monascus and Optimization of Fermentation Conditions for Monacolin K Production
摘要
Abstract
A strain of Monascus purpureu was treated with UV irradiation and its spore was then incubated in media containing LiCl to induce mutation.A mutant strain with high yield of monacolin K was obtained and its fermentation conditions were optimized for monacolin K production.The results showed that the optimal fermentation conditions were initial temperature of 30 ℃,late temperature of 24 ℃ and original moisture content of germinated brown rice of 60%.Under these conditions,the yield of monacolin K reached 5.33 mg/g.关键词
