Production of protein-rich fungal biomass in an airlift bioreactor using vinasse as substrate

► The optimal aeration rate for fungal fermentation was 1.5 vvm. ► The highest fungal biomass yield was 8.04 (gbiomass increase/ginitial biomass). ► The influent organic matter was reduced by 80%. ► The fungal protein contained approximately 7.8% lysine (on a total protein basis).
