โœฆ Synopsis

Citric acid production in surface culture process with reuse of mycelia for more than one batch of media has been reported in this work. A strategy for replacing media and thus increasing productivity in subsequent batches is discussed. An explanation for the decrease in citric acid accumulation beyond the second batch is suggested on the basis of oxygen limitation. I

Models for the known glucose transporters in Aspergillus niger and for simple diffusion of glucose through the hyphal membrane were prepared. The results from the models were compared with fermentation data from published studies on citric acid. It was found that the purely physical and uncontrolled
