Problem 2 Nitrification by Nitrosomonas Sp. Fixation of CO2 to biomass can be driven by a simultaneous oxidation of NH; to nitrite. The overall reaction is - CO2 - (a +0.2)NH3 - (1.5a - 1.05)O2 + CHLs 00.5 No.2 + HNO2 + (a -0.6H20 = 0 (1) Reaction (1) can be divided into two separate chemical reactions which run in parallel: - CO2-0.2 NH3 -0.6H20 + CH 18 0 0 N 0.2+ 1.05 O2 = 0 - NH3 - 1.5 02 + HNO2 + H20=0 (2) (3) Determine AG for each of the two reactions (1) and (2). Determine the minimum value of parameter a in (1) for the whole process to be thermodynamically feasible. Chemolithotrophic bacteria such as Nitrosomonas are thermodynamically quite inefficient. Assume a thermodynamic efficiency of 30% for fixation of CO2 and calculate the maximum yield of biomass on NH3
