Rhizopus is a genus of mold belonging to the Zygomycetes group, commonly known as black bread mold. It typically grows on decaying organic matter and is characterized by its fast growth and filamentous structure. Rhizopus species are often used in industrial applications, such as fermentation and the production of certain foods, like tempeh. However, some species can also be opportunistic pathogens, potentially causing infections in humans, particularly in immunocompromised individuals.
