Precision fermentation

Precision fermentation is a production process in which specific biological molecules are manufactured using microorganisms. It can be used to produce food ingredients that are conventionally sourced from animals and plants, including proteins, lipids, carbohydrates, and other metabolites. Bacteria, yeast, or other cell types produce large quantities of a specific compound which is then extracted and purified from the fermentation broth or cell lysate. For example, milk or egg proteins, dairy fats, functional oligosaccharides, flavour and colour compounds or vitamins. Precision fermentation is different from other forms of fermentation used in the food industry because it produces a single target molecule with high precision and purity. In other approaches like traditional fermentation or biomass fermentation, the product contains a mix of fermentation outputs, biomass, and substrates. This precision is achieved by optimising both the culture conditions and the microbial strains used in the process. While it is possible to use organisms that naturally produce useful ingredients, in some cases engineered strains are developed using adaptive laboratory evolution, mutagenesis, or by introducing specific gene sequences. The purification and extraction process ensures that genetically engineered organisms are not present in any final products.…

Although the term "precision fermentation" is relatively new, the underlying technologies have been used since the 1980s. Proteins like insulin for diabetes treatment or chymosin (rennet) for cheese manufacturing have been produced by these techniques for decades and are well integrated in the market. Precision fermentation incorporates genetic tools, synthetic biology approaches and strain engineering techniques, and it has a promising role in future biobased food production systems. It is expected to become an essential technology in a global shift towards more sustainable food systems, in the context of climate change and in areas where the availability of agricultural land is limited.
