Fermentation is widely used across industries, from food and pharmaceuticals to biofuels and materials. In food, it enhances preservation, nutrition, and flavor, producing products like yogurt, cheese, and kombucha. In pharmaceuticals, microbial fermentation enables the production of antibiotics, vaccines, and biologics. Agriculture benefits through fermented feed additives and biofertilizers, while industrial applications include enzyme production and biodegradable plastics. Emerging sectors like alternative proteins and sustainable fuels rely on fermentation to develop environmentally friendly solutions.
