Fungal Biology

Fungal Biology is the specialized field within biology and microbiology dedicated to the study of fungi—a diverse kingdom of eukaryotic organisms including yeasts, molds, and mushrooms. This discipline investigates their unique cellular structures with chitinous walls, their genetics, metabolism, and reproductive strategies, which commonly involve spores. It also explores the critical ecological roles fungi play as decomposers and symbionts, as well as their direct impact on humans as pathogens, sources of antibiotics, and essential tools in fermentation and biotechnology.
