Aromatic alcohols are liable to result in enzyme inactivation. A novel strategy was established for improving the aromatic alcohol tolerance of β-galactosidase (BMG) from Bacillus megaterium YZ08. The half-life of BMG in 200 mM vanillyl alcohol solution was dramatically increased by 9–123 times with the addition of hydrophilic solvents. In 30% DMSO, the reaction concentration of aromatic alcohol could
