In environmental engineering dealing experimental design. Fed-batch fermentation is a modified version of batch fermentation. It is the most common mode of operation in the bioprocess industry. Microorganisms are inoculated and grown under batch regime for a certain amount of time, then nutrients are added to the fermenter in increments Combining all this into equation 20, and canceling the term P ih i dn i dt that shows up on both sides of the equation, we obtain V X i c ic p;i dT dt d(PV) dt = UA(T T a) + Qin X i c p;ic in i!
