Experimental measurements on the aerobic oxidation of acetate by a microorganism show that 30% of the carbon in the substrate (acetic acid) is converted to biomass (X) of an average formula CH1.900.5No.4 according to the overall metabolic reaction below: CH3COOH + a NH3 + b 02 c CH1.900.5 No.4 + d CO2 + e H20 i) Calculate the stoichiometric coefficients of the reaction above (a to e) (7 points) ii) How many grams of oxygen (O2) are consumed per gram of biomass produced (Yoz/x)? (3 points)
