Fungal biomass refers to the total mass of fungi in a given environment, including their cells, tissues, and spores. It plays a crucial role in ecosystems, contributing to nutrient cycling and organic matter decomposition. Fungi, such as mushrooms and yeasts, are essential for breaking down complex organic materials, making nutrients available for other organisms. In addition to their ecological importance, fungal biomass is increasingly recognized for its potential in various industries. It can be used in biotechnology for producing enzymes, biofuels, and even food products. The sustainable cultivation of fungal biomass offers promising avenues for reducing waste and enhancing food security.
