  • Method for producing pyruvic acid by fermentation
    Patent number: 4918013
    Abstract: The present invention relates to a method for producing pyruvic acid.This method consists of first producing Candida type cells at approximately 5 pH by using a culture medium comprising thiamine and then producing pyruvic acid by culturing cells at about 4 pH by using a culture medium not containing thiamine or iron. Therefore, the production of pyruvic acid (curve I) is favored by limiting the production of alpha-ketoglutaric acid (curve II).
