Building on ancient techniques with precision fermentation for alternative proteins
A sustainable, scalable path to animal-free proteins, transforming the future of food
The global food system is under pressure to feed a growing population while tackling sustainability and environmental issues. Traditional meat and dairy farming, known for its heavy resource use, is being questioned. Precision fermentation (PF) offers a path to produce proteins with significantly lower environmental impact. Based on standard-reviewed LCAs from PF startup Perfect Day, this process can reduce land use by up to 99%, water consumption by 94%, and greenhouse gas emissions by 97% compared to traditional animal agriculture.1 The Good Food Institute projects that precision fermentation could capture up to 20% of the protein market by 2035, representing a market value of $290 billion.2
Precision fermentation explained
Unlike traditional fermentation, precision fermentation is an advanced biotechnology, which leverages naturally occurring microorganisms to transform substrates. PF uses genetically engineered microbes as 'cell factories' to produce specific molecules.3 The process begins with selecting a target molecule, such as proteins, peptides, or enzymes. Next, a microbial strain is engineered by inserting a gene that encodes the 'recipe' for the target molecule, often using genetic sequences derived from other organisms. These engineered microbes are then fed with a substrate - traditionally glucose. In the bioprocessing step, the microbes are cultivated in bioreactors under optimal conditions to produce the target molecule and finally, the produced ingredient is isolated, purified, and applied in food products. This sophisticated process allows for precise control over production, enabling the creation of animal-identical proteins and other ingredients without animal involvement.4

From lab to market: emerging players and opportunities
The PF market is growing rapidly, with projections indicating significant expansion in the coming years. According to Coherent Market Insights, the global PF market is estimated to be valued at USD 4.21 billion in 2024 and is expected to reach USD 45.80 billion by 2031, exhibiting a compound annual growth rate (CAGR) of 40.6% from 2024 to 2031.6

Several startups are actively developing sustainable, animal-free alternatives to traditional food products. Perfect Day specializes in producing milk proteins, such as casein and whey, for dairy alternatives, while Motif FoodWorks focuses on developing heme proteins for plant-based meat products. Formo, based in Germany, has adopted a dual strategy approach. Initially, the company utilized traditional fermentation methods (micro fermentation, as they name it), specifically using koji protein derived from Aspergillus oryzae, to produce animal-free cheese without genetic modification. This approach facilitated quicker market entry for products like their cream cheese alternative.
Going lab to plate and some regulatory roadblocks
The regulatory environment for precision fermentation products poses significant challenges for market entry. Novel foods manufactured using this technology must go through an application process in key markets, including the US and EU, which can take one to four years. The EU's stringent food safety standards require extensive pre-market safety assessments, which can delay product launches by months or years. In addition, labeling requirements for genetically modified ingredients can affect consumer perception and acceptance. Achieving cost parity with traditional animal products remains a hurdle that requires further technological advances and economies of scale. Inconsistent global regulations make international market expansion difficult, and proving the safety of new ingredients can be both time-consuming and costly.
In response to these challenges, key players in the precision fermentation space have formed the Precision Fermentation Alliance (PFA), aimed at improving the regulatory framework for fermentation-enabled foods.8 The alliance seeks to enhance transparency and efficiency in the regulatory process while maintaining existing food safety standards.
The road ahead
As precision fermentation technology matures, we can expect to see a wider range of animal-free proteins and ingredients entering the market. The success of this technology will depend on continued innovation, regulatory adaptation, and consumer acceptance.
While precision fermentation is not a silver bullet for all food system challenges, it could represent a significant step towards a more sustainable and resilient protein supply.
