MEDIUM FOR HIGH PRODUCTION OF SUCCINIC ACID

摘要

PURPOSE: A succinic acid culture medium with high productivity is provided to mass produce the succinic acid at low cost by mixing expensive yeast extract with low price corn precipitate at optimal rate. CONSTITUTION: A succinic acid culture medium comprises 125-195g/l of glucose, 6-18 g/l of yeast extract, 15-40 g/l of corn precipitate, 8-12 g/l of sodium hydrogen carbonate and 90-110 g/l of magnesium carbonate. The succinic acid production cell group is Actinobacillus succinogenes. A manufacturing method of the succinic acid comprises the following steps: cultivating the succinic acid production cell group in the culture medium; and obtaining the succinic acid from the culture fluid.
