PROCESS FOR PRODUCING ORGANIC ACID

摘要

This invention is intended to improve the efficiency of organic acid fermentation in a simple manner without mutant breeding, DNA recombination breeding, or other means, when producing an organic acid via fermentation with the use of yeast that produces the organic acid of interest. The efficiency of the yeast's ability to produce organic acid is significantly improved by treating yeast that produces an organic acid in an organic-acid-containing medium having a low pH value.
