Precision Fermentation for Alternative Proteins

Detailed overview of innovation with sample startups and prominent university research


What it is

Precision fermentation for alternative proteins involves using microorganisms, such as bacteria, yeast, or fungi, to produce protein-rich ingredients or complete protein products through a controlled fermentation process. This technology offers a sustainable and efficient alternative to traditional protein sources, such as animal agriculture and plant-based proteins, addressing concerns about environmental impact, animal welfare, and food security.

Impact on climate action

Precision Fermentation for Alternative Proteins in the realm of Low-Carbon Food revolutionizes climate action by offering sustainable protein sources with minimal environmental impact. By optimizing production processes and reducing resource inputs, this innovation mitigates greenhouse gas emissions, conserves land and water, and fosters a more sustainable food system.

Underlying
Technology

  • Fermentation: Fermentation is a metabolic process where microorganisms convert organic substrates into desired products, such as proteins, enzymes, or organic acids. In the context of alternative proteins, fermentation is used to produce protein-rich ingredients or complete protein products.
  • Microbial Engineering: Genetic engineering and synthetic biology techniques are used to modify microorganisms to produce specific proteins with desired amino acid profiles, functional properties, and nutritional value.
  • Bioreactors: Bioreactors provide a controlled environment for fermentation, optimizing conditions such as temperature, pH, and nutrient availability to maximize protein yields.
  • Downstream Processing: After fermentation, the protein products need to be separated and purified from the fermentation broth.
