Steps:

2.6. Optical resolution of racemic methyl lactate by PHE14

A standard 500-μL hydrolytic reaction system containing140 μg purified esterase PHE14, 50 mmol/L substrate (racemicmethyl lactate) and 50 mmol/L phosphate buffer (pH 7.5) wasincubated at 37 °C for 1 h. After the completion of the enzymaticreaction, reaction samples were extracted with an equalvolume of ethyl acetate and the organic phase was further analyzedto evaluate the enzymatic resolution of (±)-methyl lactate.
