Abstract
The present invention relates to an acid-resistant yeast endowed with a lactic acid production ability and having a suppressed ethanol production pathway, and a method for producing lactic acid using same. According to the present invention, by effectively suppressing the production of ethanol in an acid-resistant yeast, and by expressing an LDH enzyme with strong expression and high efficiency, it is possible to produce lactic acid with high yield even at low pH without degrading growth.
