CLAIMS

What is claimed is:

1. An isolated Saccharomyces cerevisiae microorganism having enhanced productivity of lactic acid, wherein the microorganism is modified so that: a) the activity of pyruvate decarboxylase (PDC) of the microorganism is decreased compared to that of a non-modified lactic acid-producing strain; andb) the activities of aldehyde dehydrogenase (ALD) and acetyl-CoA synthetase (ACS)...

DESCRIPTION

TECHNICAL FIELD

The present invention relates to a lactic acid-producing recombinant Saccharomyces sp. microorganism, and a method for producing lactic acid from the culture medium containing the microorganism by culturing the same.
