Acid-resistant ester-producing monascus strain and method for improving ester-producing capacity by mutagenesis

The invention discloses an acid-resistant ester-producing monascus strain and a method for improving ester-producing capacity through mutagenesis, the acid-resistant ester-producing monascus strain is TB Monascus 2022ARTP and is preserved in the China General Microbiological Culture Collection Center (CGMCC), and the preservation number is CGMCC No.40576. The acid-resistant ester-producing monascus strain has the advantages that the acid-resistant ester-producing monascus strain can be used for producing ester; the monascus enzyme strain provided by the invention has strong acid resistance, and can normally grow in an environment with pH of 3.5; esterifying enzymes can be generated and esterified in the fermentation process of the white spirit to generate various ester substances, so that the flavor of the white spirit is increased; after the strain is subjected to ARTP mutagenesis, the ester production capacity of the strain is improved by 7 times. 本发明公开了一种耐酸产酯红曲霉菌株及诱变提升产酯能力的方法，所述耐酸产酯红曲霉菌株为TB Monascus 2022AR
