The recovery of penicillin from the acidified fermentation broth is done by__________________?
Correct answer: D. Liquid extraction
- A. Distillation
- B. Evaporation
- C. Absorption
- D. Liquid extraction
Explanation
Acidification converts penicillin into a form that preferentially partitions into an immiscible organic solvent, so liquid-liquid extraction is used. Distillation and evaporation would expose the heat-sensitive antibiotic to unnecessary heating.
