Aerobic degradation of an organic compound by a mixed culture of organisms in waste water can be represented by the following reaction.

C3H6O3 - ?O O2 - ?NH NH3 ?? ?X C5H7NO2 + ?W H2O+ ?CO CO2

a). Determine ?O,?X, ?W, VNH and ?CO if YF x/s (Yield Factor biomass/sugars) = .4g-x/g-s

b). Determine the yield factors YF x/o2, YF x/no3

c). Determine the degree of reductions for the substrate, bacteria, and the respiratory quotient RQ=vCO2/(-vO2) for all organisms.
