ABSTRACT:
An improved fermentation process for producing carboxylic acids is disclosed. The improvement comprises growing fungi of the genus Rhizopus in a culture medium containing a carbon source, a nitrogen source and inorganic salts, under conditions of controlled oxygen availability wherein the dissolved oxygen concentration for the cell growth phase is between 80% and 100% and where the dissolved oxygen concentration for the acid production phase is between 30% and 80%.
