Solid wastes emanating from food and hospitality domains constitute environmental challenges and their holistic management remained inevitable. Solid state bioconversion process involving mixed culture of microbes was conducted for 7 days. Bio-product synthesis by the microorganisms and bio-degradation extent of fruit peels’ components were analyzed for chemical and structural changes. Chemical analysis showed improved protein enrichment when microbes were mixed together at different ratios (141.18 mg/g) compared with 4 cm apart (115.62 mg/g). Through substrate reformulation, fermentable sugar composition rose to 500.99 mg/g and protein enrichment increased to 160.68 mg/g, cellulase activity was 1.33±0.04 units/ml and α-amylase activity of 112.46±0.28 units/ml was synthesized. Analysis of reformulated substrates indicated presence of more metabolizable sugar while FT-IR analysis revealed immense modifications and consumption of complex sugars (cellulose, hemicellulose and lignin) by selected filamentous fungi
