SOLVED: Determine stoichiometric coefficients (a, b, c, and d), biomass yield coefficient, and oxygen yield coefficient for aerobic biodegradation of benzoic acid by microorganisms as represented by the following reaction: C6H5COOH aO2 bNH3 → cC5H7NO2 dH2O eCO2. The value of RQ should be considered as 0.66 for this fermentation process.

SOLVED: Write a balanced reaction for the aerobic biodegradation of casein (C6H12O6N2) to form biomass (C6H10O2N), CO2, and H2O. Assume that the yield is 0.49 g biomass synthesized per g of casein consumed. (Hint: Use the yield value to compute moles biomass per mole of casein.)b) Determine the BOD or amount of oxygen (in mg/L) needed to biologically oxidize a 100 mg/L solution of casein.c) Write a balanced equation for the chemical oxidation of casein as in the COD test. Estimate the COD (in mg
