Ethanol is to be used as a substrate for single-cell protein
production in a chemostat. The available equipment can achieve an oxygen
transfer rate of 10 g O2/l of liquid per hour. Assume the kinetics
of cell growth on ethanol is of the Monod type, with µm = 0.5 h–1, Ks
= 30 mg/l, YX/S = 0.5 cells/g ethanol, and YO2/S = 2 g O2/g EtOH. We wish to
operate the chemostat with an ethanol concentration in the feed of 22 g/L. We
also wish to maximize the biomass productivity and minimize the loss of unused
ethanol in the effluent. Determine the required dilution rate
