METHOD FOR PREPARING REBAUDIOSIDE M BY USING SACCHAROMYCES CEREVISIAE ENZYMATIC PROCESS

摘要

Provided in the present invention is a method for preparing rebaudioside M by using an enzymatic process, which catalyzes the formation of rebaudioside M using a recombinant Saccharomyces cerevisiae containing a UDP-glucosyltransferase or a UDP-glucosyltransferase prepared therefrom. The recombinant Saccharomyces cerevisiae is obtained by transforming an expression vector containing the UDP-glucosyltransferase gene under the control of a strong promoter.
