Both Saccharomyces cerevisiae yeast and Zymomonas mobilis bacteria produce etanol from glucose under anaerobic conditions without external electron acceptors. The biomass yield from glucose is 0.11gg-1 for yeast and 0.05gg-1 for Z. mobilis. In both cases the nitrogen source is NH3. Both cell compositions are represented by the formula CH1.8O0.5N0.2.
a) What is the yield of etanol from glucose in both cases? Use Matlab to solve the elemental balance.
b) How do the yields calculated in (a) compare with the thermodynamic mximum?
