This study examined the potential of producing an edible fungus, Rhizopus microsporus var. oligosporus, on biodiesel-derived crude glycerol. Prolific fungal growth was observed with a fungal biomass yield of 0.83 ± 0.02 (g biomass increase/g initial biomass) under optimal cultivation conditions (e.g. nonsterile crude glycerol at a concentration of 75% (w/v) with nutrient supplementation and without pH control). The potential of utilizing front-end processed banagrass (Pennisetum purpureum) juice as a source of nutrients for crude glycerol fermentation was evaluated with a 2.3-fold improvement in the fungal biomass yield. The glycerol-derived fungal biomass showed high amounts of threonine, one of the main limiting amino acids in non-ruminant feeds. An inexpensive fungal protein has the potential to reduce meat product prices by lowering the production costs of animal feeds. The application of fungal technology thus provides a unique sustainable option for biodiesel refineries by providing an additional source of revenue from fungal products.
