Function loss of lysine acetylation site function regulated the “xylose consumption memory (XCM)” behaviors of S. cerevisiae. A Culture mode design induced the forgetting of XCM. The yYST210 (H4K5R) and control yYST12 strains were continuously incubated in synthetic complete-xylose medium (SX) to induce the XCM. The strains were transferred to synthetic complete-glucose medium (SG) and cultivated for 0–12 days (d), respectively, and then finally transferred to SX medium.
