Abstract
The present disclosure discloses a method for preparing lipase with high ester synthesis activity by using surfactant, belonging to the field of enzyme engineering. The present disclosure provides a method for obtaining a lipase with high ester synthesis activity by adding different surfactants with different concentrations in a lipase aqueous solution and then freeze-drying. The lipase meets the requirement in non-aqueous catalysis. Mixing a variety of lipase with no ester synthesis activity or low activity at suitable concentration and an appropriate concentration of the surfactant in the solution can produces lipases with significantly improved ester synthesis activity, meanwhile changing the hydrolytic activity of the lipase. Increased ester synthesis activity makes lipase more suitable for industrial applications.
