Description

technical field

[0001] The invention relates to a lipase mutant and its application in decontamination, belonging to the technical field of enzyme engineering. Background technique

[0002] Lipase (Lipase, EC 3.1.1.3, glyceride hydrolase) is a general term for a class of enzymes that hydrolyze fat. In some reaction systems, lipase can catalyze hydrolysis, alcoholysis, transesterification, hydrogenolysis, and indirect redox transesterification. In addition, lipase also has the ability to hydrolyze racemic mixtures and synthesize esters and synthesize peptide bonds. Therefore, lipase has important applications in many fields, such as:

[0003] 1. Lipase can be used in oil processing, and the lipase hydrolysis of oil can be carried out at normal temperature and pressure, so it will not denature biological substances such as highly unsaturated fatty acids and tocopherol in oil;

[0004] 2. Lipase can be used in dairy processing. Applying lipase to hydrolyze milk fat in dairy p...
