  • STREPTOMYCES STRAIN AND THE METHOD OF CONVERTING FERULIC ACID TO VANILLIN BY USING THE SAME
    Publication number: 20090186399
    Abstract: A method of vanillin production from ferulic acid with a high concentration by biotransformation using a Streptomyces sp. strain is claimed in this invention. This strain is named as Streptomyces sp. V-1, which has been deposited in China Center for Type Culture Collection on Jul. 12, 2006 with the number of CCTCC M 206065. Using this strain, high concentration of vanillin fermentation broth is obtained from ferulic acid by biotransformation in GY biotransformation medium. With the addition of macroporous adsorbent resin DM11, the concentration of vanillin can be greatly improved. The advantage of this invention is less environmental pollution, high product concentration, less by-product, short processing cycle, low production cost, simple product extraction, clean production process, product environmental friendly, safe and reliable, which solves many difficulties in the vanillin production from botanical raw material extraction or chemical synthesis, and therefore it has good application prospect.
