textbook) Stoichiometry and Incomplete Reactions page For production of penicillin (C6H18ON₂S) using Penicillium mold, glucose (C6H12O6) is used as a substrate and phenylacetic acid (C,H,O₂) is added as a precursor. The stoichiometry for overall synthesis is: 1.67 C6H12O6+2NH3 + 0.50₂+ H2SO4 + C₂H₂O₂ → C16H1804N2S+2CO₂+ 9H₂O a) What is the maximum theoretical yield of penicillin from glucose in g/g? b) 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. c) Batch fermentation under the conditions described in part b) is carried out in a 100-liter tank. Initially, the tank is filled with nutrient medium containing 50 g L' glucose and 4 g L' phenylacetic acid. If the reaction is stopped when the glucose concentration is 5.5 g L, determine: (0) Which is the limiting substrate if NH3, O2, and H,SO, are provided in excess (ii) The extent of reaction (i) The total mass of glucose (in grams) used for growth (iv) The amount of penicillin (in grams) produced (v) The final concentration of phenylacetic acid in g/L
