The aimof thsi study is to optimize the cultivation of fungal biomass on volatile fatty acids derived from acidogenic fermentation of organic residues and to evaluate the extent and rate of degradability of fungal biomass in rumen in vitro systems. Aspergillus oryzae biomass, grown on glucose and volatile fatty acid (VFA) effluents recovered from anaerobic digestion of organic waste, was investigated for in vitro behaviour compared to silage and rapeseed meal. The next step of the experiment was performed by evaluating the rumen in vitro digestibility of the produced fungal protein biomass compared to rapeseed meal (ExPro) and silage. Results showed that the produced fungal biomass contained 41-49% crude protein, 41-55% neutral detergent fiber (NDF) while the silage and rapeseed used as control contained 18% and 39% crude protein respectively. The residues of various biomasses after digestion were …
