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:
Assuming 100% conversion, what is the yield of cells from hexadecane in g g-l?
