  • Patent number: 10227618
    Abstract: The present application relates to a microorganism of the genus Saccharomyces producing lactic acid and a method for preparing lactic acid using the same. More specifically, the present application relates to a microorganism of the genus Saccharomyces producing lactic acid, wherein the microorganism is modified to weaken or inactivate the activity of pyruvate decarboxylase (PDC) compared to its endogenous activity, to introduce the activity of ATP-citrate lyase (ACL), and to enhance pyruvate biosynthetic pathway compared to its endogenous biosynthetic pathway, and a method for producing lactic acid using the microorganism.

  • Patent number: 9689009
    Abstract: The present invention provides methods for the production of cysteine or derivates thereof by culturing a microorganism having reduced activity of endogenous phosphoserine phosphatase and the activity of PhnC, PhnD, and PhnE is reduced, and enhanced activity of phosphoglycerate dehydrogenase and/or phosphoserine aminotransferase. The O-phosphoserine produced by such an organism can then be reacted with a sulfide in the presence of a sulfydrylase or a microorganism expressing a sulfhydrylase to produce cysteine or a derivative thereof. Microorganisms having these reduced and enhanced properties noted above are also provided herein.
