Precision fermentation for improving the quality, flavor, safety, and sustainability of foods.

Precision fermentation involves the rewiring of metabolic pathways in generally recognized as safe microorganisms, fermentation scale-up, and downstream processing to produce food ingredients from abundant and inexpensive substrates. Using precise genome editing of food-fermenting microorganisms, precision fermentation can also produce fermented foods with more desirable properties. These genetic tools allow for the manipulation of flavors and nutritional content in fermented foods, the economic production of functional food ingredients, and the sustainable production of otherwise-costly macronutrients.
