Precision-fermented dairy at parity
Projection
Microbes brewed in tanks make milk and egg proteins as cheaply as cows and hens.
Engineered yeasts and fungi secrete specific animal proteins, such as whey and casein, identical to the originals. Price parity would cut land use and emissions from dairy and eggs sharply.
Why it’s plausible: Several products are already on sale at a premium; parity depends on large fermentation capacity and cheaper downstream purification.
