Stoichiometric equations are used to represent growth of
microorganisms provided a ' molecular formula' for the cells is available. The
molecular formula for biomass is obtained by measuring the amounts of C, N, H,
O and other elements in cells. For a particular bacterial strain, the molecular
formula was determined to be C4.4H7.30 1.2N0.86 . These bacteria are grown
under aerobic conditions with hexadecane (C16H34) as substrate. The reaction
equation describing growth is:
You have been put in charge of a small fermenter for growing the bacteria and aim to produce 2.5 kg of cells for inoculation of a pilot-scale reactor. What minimum amount of hexadecane substrate must be contained in your culture medium?

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
