Aspergillus niger was used in a process called solid-state fermentation to produce a protein enriched substrate in three different agro-wastes as substrates which was banana peel, papaya peel and pineapple peel. Several fermentation parameters were optimised which include incubation temperature, incubation period, and moisture level. All of those parameters have effect on the fungal growth and also the enrichment of the protein. The highest protein producer which was papaya peel was tested under variable parameters. The best SSF condition for producing high yield of protein for papaya peel was 30°C of incubation temperature, 6 days of incubation period and 70% of initial moisture content which gave 0.231 mg/ml of protein.
