PROCESS FOR PREPARING DICARBOXYLIC ACIDS EMPLOYING FUNGAL CELLS

摘要

The present invention relates to a process for producing a dicarboxylic acid comprising fermenting a fungal cell in a vessel comprising a suitable fermentation medium, comprising adding a gas flow which comprises 20 to 35 v/v% of oxygen and less than 0.1v/v% of carbon dioxide to the fermentation medium, and maintaining an average partial carbon dioxide pressure of at least about 0.35 bar in the fermentation medium, and producing the dicarboxylic acid.
