Full TextAbstract
A structured unsegregated cybernetic model able to describe a diauxic growth phenomena of cells colony in aerobic condition. It empowers microorganisms to allocate cellular resources for the uptake of those substrates that best fit the cellular requirements. In this project, at first, the result of simulation in batch bioreactor has been brought and shown how cells concentration and ethanol concentration are changing with time. Then for simulating fed batch system, at first, the optimal substrate feeding in to bioreactor has been obtained by solving optimal control problem. Finally, for preventing of oxygen starvation that causes ethanol production, oxygen mass transfer coefficient is simulated on the function of impeller speed and air flow rate and then control of oxygen concentration by PI and GLC controller have been considered.
