Abstract
This study was conducted to determine the potential of four fungi associated with vermicast namely; Aspergillus niger, Rhizopus stolonifer, Aspergillus fumigatus and Rhizomucor pusillus as sources of single cell protein using banana fruit peel as substrate. This study is about the production of single cell protein wherein proximate composition of the protein enriched banana peel and percentage increase in crude protein content were determined.
Results revealed that incoulation of fungi from vermicasr could affect the proximate composition of the banana fruit peel. For the crude protein content (CPC), R. stolonifer obtained the highest CPC at 6.29% while R. pusillus and A. fumigatus obtained the lowest CPC of 4.14% and 4.05%. Similarly, on the percentage increase CPC, R. stolonifer recorded the highest increase in CPC of 10.73% meanwhile, reduction of 28.64% and 27.11% were observed in A. fumigatus and R. pusillus respectively. For the proximate composition analysis, both increment and reduction in moisture, ash, crude fat and crude fiber content of the banana fruit peel were recorded. For the moisture content, A. fumigatus had the highest moisture of 38.62% while R. stolonifer had the least with 12.37%. Meanwhile, A. niger recorded the highest ash content of 12.03%, while A. fumigatus and R. pusillus recorded the lowest content of 8.35% and 8.28% respectively. For the crude fat, R. stolonifer obtained the highest content with 12.43% while A. fumigatus and R. pusillus obtained the lowest content with 7.90% and 7.88% and lastly for the crude fiber, R. obtained recorded the highest content with 12.81% while A. fumigatus obtained the lowest content with 8.32%.
