Kinetic analysis of penicillin production by semicontinuous fermenters

The relationships between the specific rate of nutrient consumption and biomass growth and between the specific rate of penicillin production and oxygen concentration in the broth are analyzed. The functional dependencies which have been obtained from the experimental data of industrial fermenters are used with the mass balances to develop a model of the behavior of semicontinous operations. The proposed model allows one to study the influence of some operational parameters. The obtained results agree with the data of industrial processes.
