The present invention discloses a p-nitrobenzyl esterase mutant and its encoding gene, a genetically engineered bacterium containing the p-nitrobenzyl esterase mutant, and its application in the chiral resolution of dl-menthyl esters by enzymatic catalysis to prepare l-menthol. The p-nitrobenzyl esterase mutant is obtained by combinatorial mutation of the amino acid residues at positions 109, 110, 193, 270, 273, 314 or 362 of the p-nitrobenzyl esterase with the amino acid sequence shown in SEQ ID NO.2. The beneficial effects of the present invention are mainly reflected in: ① The esterase mutant of the present invention does not need to add a cosolvent, and the enzymatic catalytic activity maintains a relatively high level; ② In the cosolvent-free system, the stereoselectivity of the mutant enzyme-catalyzed reaction is significantly improved compared with the wild type. These mutant enzymes are overexpressed in Escherichia coli and used for catalytic reactions, and dl-menthyl acetate at a concentration of 20-200 g / L is used as a substrate for hydrolysis resolution to prepare l-menthol. The results show that the ee p value of the product l-menthol > 99%, and the substrate conversion rate > 95%, showing good industrial application performance.
