Rhizopus is a genus of common saprophytic fungi on plants and specialized parasites on animals. Rhizopus species grow as filamentous, branching hyphae that generally lack cross-walls (i.e., they are coenocytic). Rhizopus fermentation offers a sustainable and cost-effective method for producing various products with commercial and industrial value, making it an important process in the biotechnology and food industries.

R. oligosporus and R. oryzae belong to the GRAS (generally recognized as safe) species, which do not synthesize toxic secondary metabolites. Fermentation with Rhizopus has been traditionally used to process by-products of plant oil pressing into a food product. Food-grade Rhizopus strains have been proved that fermentation process could be an effective method for enhancing the bioactive and nutritious parameters. It is worth noting that Rhizopus moulds, unlike A. oryzae, produce abundant, strong mycelium, making it possible to obtain products of defined and compact structure. Among the studied strains, R. oligosporus and R. microsporus are of particular interest, as well as R. oryzae with respect to amino acid composition. The products obtained through fermentation can be considered a new bioprocessed form with the prospective application in food production.
