Fusarium venenatum is a type of fungus that is primarily known for its use in producing mycoprotein, a meat substitute. This fungus is cultivated in controlled environments, where it grows rapidly and can be harvested in just a few days. The mycelium of Fusarium venenatum is rich in protein and fiber, making it a nutritious option for vegetarian and vegan diets. The most famous product derived from Fusarium venenatum is Quorn, a brand of meat alternatives. The fermentation process used to grow this fungus allows it to develop a texture similar to meat, which appeals to those looking for plant-based protein sources.
