摘要：A process for increasing the production rate of citric acid during thefermentation by the fungus Aspergillus, preferably wherein the fungus is grown inpresence of air, using a substrate with no trace metals, and with an increased initialsucrose concentration compared to conventional media, and subsequently to theinitiation of acid excretion the fermentation broth is diluted instantly to 35 to 65%,preferably 40 to 60%, most preferred to 50% of the initial sucrose concentration bymeans of water, while afterwards the fermentation and the isolation of the acid proceedin a conventional manner.
