Ensuring the integrity of our food sources through advanced biotechnology: Precision Fermentation
In the face of a protracted food security crisis, driven by economic turmoil from the COVID-19 pandemic, climate change, and food price shocks resulting from the war in Ukraine, a novel form of food production is gaining traction as a transformative solution. This innovative approach, known as precision fermentation, could help society more easily weather food security crises.
Precision fermentation involves turning microorganisms into mini-factories, producing specific enzymes or protein ingredients. Companies like Perfect Day and Remilk are moving beyond proof-of-concept to commercial scale, with partnerships from major food players such as Nestlé and Mars, demonstrating confidence in its market viability and scalability.
This technology allows production in controlled environments, significantly reducing environmental impacts. Compared to conventional farming, precision fermentation offers advantages in stability of supply chains (less dependency on climate-variable crops), lower environmental footprint, and the ability to produce identical or superior proteins and ingredients on demand.
While challenges remain around production costs and supply chain integration, advances in metabolic engineering allow the use of abundant low-cost feedstocks such as lignocellulosic biomass and food waste to improve economic feasibility and sustainability. Further innovation is focused on improving process efficiency through enhanced bioreactor designs, continuous fermentation processes, and tailored formulations to meet consumer taste and functionality expectations.
ImaginDairy, an Israeli firm, recently raised $28 million to fund the development of dairy proteins produced via precision fermentation. Other companies, like Solar Foods, are developing ways to convert carbon dioxide from the air into sustainable protein using just a vat of bacteria and electricity. LanzaTech generates 50,000 tons of ethanol and 3,000 tons of protein annually from gas emissions in a plant in China. Protera uses precision fermentation to develop protein ingredients that can improve the shelf life of baked goods like bread.
Deep Branch uses microbes to turn carbon dioxide into sustainable protein for animal feed, with a slight difference from precision fermentation as the microbes are an ingredient in the final protein product. The main precision fermentation capacity is in the hands of multinationals like DuPont and Cargill, and their space is typically reserved for lucrative products. However, more added capacity to the tank space for precision fermentation is expected, including new facilities.
The raw materials needed to fuel precision fermentation range from sugars from waste biomass to greenhouse gases in the air, potentially allowing us to transition to a circular, low-waste bioeconomy. The adoption of electric vehicles could create demand for efficient battery storage, which could benefit industries like precision fermentation.
In summary, precision fermentation is transitioning from niche to mainstream with a promising outlook to help address food security by reshaping supply chains, reducing environmental impact, and gradually lowering costs to compete effectively with traditional farming methods. As investments in this sector continue to grow, it's clear that precision fermentation will play a significant role in ensuring global food security in the coming decades.
