Zusammenfassung:The present relates to a yeast strain and use thereof and a preparation method of ergothioneine. The present invention relates to the field of biotechnology. The yeast strain is obtained through traditional mutagenesis and screening, and its deposit number is CCTCC M 20211505. The present invention provides a preparation method of ergothioneine. The preparation method of ergothioneine comprises: mixing the aforementioned yeast strain with a fermentation medium and an optional substrate, fermenting, and then homogenizing cells and separating to obtain ergothioneine. The aforementioned yeast strain can be used for the preparation of ergothioneine, and the ergothioneine prepared by the yeast strain has the advantages of high yield, low cost and fast preparation speed. The preparation method has the advantages of low cost, environmental protection, high product quality, high yield, less impurities, less drug residues, short fermentation period and the like.
