Номер: CN116121094A
Принадлежит:

The invention discloses a saccharomyces cerevisiae engineering strain with high yield of ceramide. The saccharomyces cerevisiae engineering strain is obtained by knocking out a YML115C gene as shown in SEQ ID NO.1 from saccharomyces cerevisiae host bacteria, and an amino acid sequence coded by the YML115C gene is as shown in SEQ ID NO.2. The invention further discloses a preparation method of the saccharomyces cerevisiae engineering strain. After the saccharomyces cerevisiae engineering strain constructed by the invention is fermented for 12 hours, ceramide reaches 8.90 mg/gDCW, which is 4.05 times that of a wild strain. According to the engineering strain, the ceramide yield is increased, fermentation conditions are simple, cell walls of the saccharomyces cerevisiae engineering strain are fragile, subsequent ceramide extraction is facilitated, the investment cost is reduced, and the engineering strain has wide development prospects.
