Question

Question 1:(10 Marks) Stoichiometric equations can be used to represent the growth of microorganisms provided that a "inolecular 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 the cells. For a particular bacterial strain, the molecular formula was determined to be CisH oNo.m. The bacteria are grown under aerobic conditions with hexadecane (C.sH) as a substrate. The reaction equation describing growth is as follows a) Is this stoichiometric equation balanced? If not, how would you balance this equation? (2 Mark) b) Assuming a 100% conversion rate, what is the yield of cells from hexadecane in g/g? (4 Marks) c) Assuming a 100% conversion rate, what is the yield of cells from oxygen in g/g? (4 Marks) (Hint: MM= 16g/g-mol; MM C-12g/g-mol; MM N #14g/g-mol; MM H = 18/g-mol)
