Acetobacter aceti converts alcohol to acetic acid according to the stoichiometric  relation 

 C₂H₅OH + O₂   →       CH₃COOH + H₂O 

In a vigorously agitated and aerated reactor containing 20 g/l ethanol, the organism  produces 16 g/l acetic acid and 2 g/l was the residual ethanol concentration. What are the  theoretical and observed yields of acetic acid expressed in g/g ethanol?

The growth of S.cerevisiae on glucose under anaerobic conditions can be described by the following reaction:

C₆H₁₂O₆ + aNH₃ → 0.59 CH_1.64N_0.16O_0.52 (biomass) + 0.43 C₃H₈O₃ + 1.54CO₂ + 1.3C₂H₅OH + 0.036H₂O 

and determine the product yield coefficient Y etoh/s and determine coefficient a.
