(problem 2.25 textbook, see page 41) Stoichiometry and Incomplete Reactions For production of penicillin (C16H18O4N2S) using Penicillium mold, glucose (C6H12O6) is used as a substrate and phenylacetic acid (C8H8O2) is added as a precursor. The stoichiometry for overall synthesis is: 1.67 C6H12O6 + 2NH3 + 0.5O2+ H2SO4 + C8H8O2 à C16H18O4N2S + 2CO2 + 9H2O What is the maximum theoretical yield of penicillin from glucose in g/g? When results from a particular penicillin fermentation were analyzed, it was found that 24% of the glucose had been used for growth, 70% for cell maintenance activities (such as membrane transport and macromolecule turnover) and only 6% for penicillin synthesis. Calculate the yield of penicillin from glucose in g/g under these conditions. Batch fermentation under the conditions described in part b) is carried out in a 100-liter Remember that only 6% of the glucose is used for penicillin synthesis. Initially, the tank is filled with nutrient medium…

Problem 1: For your new year's resolution, you resolve to lose 5lbs of body fat through physical exercise. If you work out hard, you can generate 200 W of mechanical power and be 20% efficient at it.
