Precision Fermentation

Precision fermentation involves inserting genetic information for a target protein into microbial DNA and mass-producing that protein through fermentation. Cheese rennet is already predominantly produced this way. Dairy proteins (casein, whey), collagen, and hemoglobin are becoming producible without animals. Unlike traditional fermentation using microorganisms' natural metabolism, precision fermentation programs microorganisms. It demands attention for both its technical possibilities and ethical questions. Precision fermentation draws attention from an animal welfare perspective, offering animal proteins without raising animals—presenting new ethical options. While traditional fermentation harnesses natural metabolism, precision fermentation programs microbes. Recognizing this difference while envisioning a future where both coexist is what is needed.
