  • Patent number: 9834794
    Abstract: The present invention relates to a method for producing retinoid from a microorganism, and more specifically, to a method for effectively obtaining retinoid, which lacks stability, from a microorganism by cultivating the microorganism capable of producing retinoid in a medium containing a lipophilic substance, and separating retinoid from the lipophilic substance.
    Type: Grant
    Filed: June 12, 2016
    Date of Patent: December 5, 2017

  • Patent number: 9725739
    Abstract: The present invention relates to a method for preparing D-chiro-inositol from myo-inositol by using a transformed host cell which expresses enzymes such as a myo-inositol transporter, inositol dehydrogenase, and inosose isomerase. According to the method of the present invention, myo-inositol can be converted into D-chiro-inositol at a high yield.
