Precision fermentation

Genetically engineered microbes as cell factories for proteins, enzymes, HMOs and flavors — a stack from strain design to purified ingredient, at 30–50 g/L target titers.

1 · What it gives

Precision fermentation uses genetically engineered microbes — yeast, filamentous fungi and bacteria — as cell factories for specific high-value molecules: dairy and egg proteins, HMOs, industrial enzymes, vitamins and flavors. Optimized strains reach 30–50 g/L of target product at >90% purity, and the cost of alternative proteins is falling on a trajectory from $10–20/kg (2020) toward a target of $3–6/kg. Versus animal agriculture the technology cuts land use by 95%, water use by 90% and greenhouse-gas emissions by 80%. The synergy is the pairing of a designed strain with a tuned upstream-downstream process and real-time PAT analytics.

Key directions of precision fermentation:

  1. Animal-free dairy proteins (Animal-Free Dairy Proteins): β-lactoglobulin and casein secreted by engineered yeast and fungi.
  2. Egg proteins (Egg Proteins): ovalbumin for baking and foaming (FDA GRAS since 2023).
  3. HMOs and bioactives (HMOs & Bioactives): 2’-fucosyllactose and lacto-N-neotetraose for infant nutrition.
  4. Industrial enzymes and flavors (Enzymes & Flavours): proteases, lipases, vanillin and terpenes via precision-fermentation strains.
