FIELD: biotechnology.
SUBSTANCE: modified microorganism is characterized by the fact that it reduces the activity of pyruvate decarboxylase, increases the activity of aldehyde dehydrogenase and acetyl-CoA synthetase, and introduces lactic acid dehydrogenase. As a result of these modifications, this microorganism is able to produce lactic acid in high yield. The invention also relates to a process for the production of lactic acid. The method comprises culturing said microorganism and isolating from the culture medium lactic acid produced by culturing this microorganism.
EFFECT: production of lactic acid in high yield.
