Zygomycetes-based biorefinery: Present status and future prospects

► Zygomycetes meet all requirements for being utilized as catalysts in biorefineries. ► Metabolites such as lactic acid, fumaric acid, and ethanol can be produced. ► Starch, cellulose, phytic acid, and proteins can be assimilated. ► Zygomycetes fungi are the source of a great diversity of enzymes. ► Potential source of single-cell protein with high nutritional value.
