28 Stoichiometry: aerobic vs. anaerobic species In order to calculate conveniently nutrient consumption, aeration, and heat-transfer rates (Chaps. 5, 8), a general stoichiometric equation can be formulated by assigning to the cell an apparent molecular formula. (a) Calculate the cell formula for the growth of yeast on sugar when it is observed to give the following balance (assume 1mol of cell is produced): 100gC6H12O6+5.1gNH3+46.63gO243.23gcellmass+41.08gH2O+67.42gCO2 (b) If the above reaction produces 0.30017 " mol" of cell, what cell formula results? (c) Anaerobic fermentations typically produce a variety of partially oxygenated compounds in addition to cell mass. Keeping the cell "molecular formula" of part (b) above, calculate the unknown coefficients for the following typical equation (coefficients are mole quantities, not mass): 0.55556glucose+ammoniacellmass 28 Stoichiometry: aerobic vs. anaerobic species In order to calculate conveniently nutrient consumption, aeration, and heat-transfer rates (Chaps. 5, 8), a general stoichiometric equation can be formulated by assigning to the cell an apparent molecular formula.
