Both the yeast Saccharomyces cerevisiae and the bacterium Zymomonas mobilis produce ethanol from glucose under anaerobic conditions without external electron acceptors. The yield of cell biomass from glucose is 150 mg/g for yeast and 75 mg/g for Z. mobilis. In both cases, the nitrogen source is ammonia (NH3) and both cellular compositions are represented by the formula CH1,8O0,5N0,2. (a) What is the yield of ethanol from glucose in both cases? (b) Based on the results of part (a), which microorganism seems most efficient for the production of industrial ethanol?
