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?
