The graph illustrates the amount of penicillin made by the fungus Penicillium in a fermenter. It also plots the concentrations of sugars, ammonium ions and Penicillium. Penicillium uses sugars as its source of food and requires ammonium ions. What can the graph tell you about the conditions required for penicillin production?
- AA high concentration of ammonium ions must be maintained.
- BMost penicillin is produced when nutrient concentrations are low.
- CPenicillium cannot produce penicillin when its concentration decreases.
- DSugars must be added constantly to the fermenter.
