  • METHOD FOR PREPARING REBAUDIOSIDE M BY USING SACCHAROMYCES CEREVISIAE ENZYMATIC PROCESS
    Publication number: 20180320211
    Abstract: 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.
