Enhancement of Volatile Fatty Acid Production from Dairy
Cell biomass balance in the fed-batch reactor leads to: (12.88)X FQ– 0 + r XV = d ( XV) dt. where XF is the concentration of cells in the feed and is usually zero or sterile. Thus, Eq. (12.88) can be reduced to: (12.89) (μ G − k d)XV = μ netXV = r XV = d ( XV) dt = XdV dt + VdX dt. or.
Fed-Batch Operation Useful in Antibiotic Fermentation → reactor is fed continuously (or intermittently) reactor is emptied periodically → purpose is to maintain low substrate concentration, S → useful in overcoming substrate inhibition or catabolic repression, so that product formation increases. By sizing a chemical reactor we mean we're either detering the reactor volume to achieve a given conversion or determine the conversion that can be achieved in a given reactor type and size. Here we will assume that we will be given -r A = f(X) and F A0.In chapter 3 we show how to find -r A = f(X).. Given -r A as a function of conversion,-r A =f(X), one can size any type of reactor. Fed-batch culture is, in the broadest sense, defined as an operational technique in biotechnological processes where one or more nutrients (substrates) are fed (supplied) to the bioreactor during cultivation and in which the product(s) remain in the bioreactor until the end of the run.
