For the production of penicillin (C₁₆H₁₈O₄N₂S) using Penicillium mold, glucose (C₆H₁₂O₆) is used as a substrate, and phenylacetic acid (C V) is added as a precursor. The stoichiometry for the overall synthesis is:
1.67C₆H₁₂O₆ + 2NH₃ + 0.5O₂ + H₂SO₄ + C₈H₈O₂ = C₁₆H₁₈O₄N₂S + 2CO₂ + 9H₂O
What is the maximum theoretical yield of penicillin from glucose in g/g?
