Value-added oil and animal feed production from corn-ethanol stillage using the oleaginous fungus Mucor circinelloides

► This study highlights the potential of thin stillage (TS) in supporting the growth of oleaginous Mucor circinelloides. ► Highest biomass yield obtained was 20 g/L (dry), with a lipid content of 46% (g of oil per 100 g dry biomass). ► Supplementing TS with crude glycerol (10%, v/v) led to 32% increase in cellular oil content. ► Concentration of γ-linolenic acid (C18:3) in Mucor-YMoil (17 wt.%) was much higher than Mucor-TSoil (1.4 wt.%). ► Efficient method of converting thin stillage into high-value fungal lipids and animal feed.
