Abstract

The present invention provides a method for high-efficiency production of pinoresinol by use of an HOauto-scavenging enzymatic cascade. It uses eugenol as the substrate, which is relatively inexpensive and is industrially available. It uses an enzymatic cascade to remove HOproduced in the process of pinoresinol synthesis, thereby reducing its inhibitory effect on the enzyme activity. In addition, the present invention uses whole cells as a catalyst, which can continuously regenerate cofactors needed by the enzyme, thus eliminating the need for exogenous addition of expensive cofactors during the reaction. The yield of the present invention can reach 7.12 g/L and the conversion rate is 61.55%.
