The present application relates to a microorganism of the genusproducing lactic acid and a method for preparing lactic acid using the same. More specifically, the present application relates to a microorganism of the genusproducing 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.

Microorganism producing lactic acid and method for producing lactic acid using same

The present invention relates tosp. capable of producing lactic acid with a decreased activity of pyruvate decarboxylase (PDC) and increased activities of aldehyde dehydrogenase (ALD) and acetyl-CoA synthetase (ACS), and a method of producing lactic acid from the culture medium obtained by culturing the microorganism.

Microorganism having enhanced productivity of lactic acid and a process for producing lactic acid using the same

The present invention relates to a method for preparing a D-lactic acid-producing strain modified to inhibit L-lactate dehydrogenase (L-LDH) activity and to introduce D-lactate dehydrogenase (D-LDH) activity in an L-lactic acid-producing strain, a mutated D-lactic acid-producing strain prepared by the above method, and a method for producing D-lactic acid including the steps of culturing the strain and recovering D-lactic acid from the culture media.

D-lactic acid-producing strain and use thereof

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.
