Evaluation of the Cultivation of Aspergillus oryzae on Organic Waste-Derived VFA Effluents and Its Potential Application as Alternative Sustainable Nutrient Source for Animal Feed

Considering the projected demand for protein supplementation in animal feed, as well prioritizing plant-based provision growing human population, great stress is imposed on conventional sources, calling new sustainable alternatives. In this regard, production and application of single-cell proteins (SCPs) has proven to be a promising alternative. Therefore, study, volatile fatty acids (VFAs) effluents recovered from anaerobically digested FW, CKM, CM, their combinations were applied cultivation edible filamentous fungi Aspergillus oryzae. The biomass was further evaluated considering its protein, fat alkali insoluble material contents. maximum fungal yielded 0.47 ± 0.00 0.37 g dry biomass/g tVFAsCODeq.consumed, with up 47% 5% content successfully cultivated shake flasks bench scale reactors, respectively. addition protein-rich biomass, significant reductions medium COD (25–58%) ammonium (33–48%) achieved. results presented research work imply that using waste-derived VFAs feed grade SCP an innovative approach can contribute economy sustainability process.
