Method for producing lactic acid and lactic acid-producing yeast mutant strain

摘要

A mutant strain of yeast that granted the lactic acid-producing ability by introducing the lactate dehydrogenase gene, lactic acid production ability in medium pH3 of mutant strains lactic acid-producing ability in lactic acid fermentation optimum pH of the parent strain of the mutant strain When producing lactic acid by culturing the lactic acid-producing yeast mutant which is characterized in that it is at least equivalent, and it is possible to simplify the alkali neutralization during culture, the lactic acid production and simplification of the lactic acid production process it is possible to lower cost.
