DICARBOXYLIC ACID PRODUCTION BY FERMENTATION AT LOW PH |
摘要 |
The present invention relates to a process for the production of a dicarboxylic acid. The process comprises fermenting a yeast in the presence of a carbohydrate-containing substrate and low amounts of oxygen at a pH value at which at least 50% of the dicarboxylic acid is in the acid form. The process of the present invention allows for high yields of the dicarboxylic acid product and is more cost-effective than existing processes in which the salt is produced which during recovery has to be converted to the acid. It also leads to a simpler and more convenient downstream processing.
