Abstract


Nigeria is the highest producer of cassava worldwide with approximation of 37.5 million metric ton yearly and this generates over 10 million metric ton of peels annually as waste. This biodegradable waste has constituted an environmental problem and poses challenges to the Ministry of Environment in Nigeria. Therefore, innovation on the conversion of this cassava peel to valuable product is a huge relief to environmental sanitation. In this study, cassava peels, rice bran and saws dust were used as substrate for cultivation of mushroom (Pleurotus ostreatus). The mushrooms were grown and harvested in 3 weeks. Mushrooms are rich in minerals; therefore, the cultivated mushrooms were subjected to Calcium, Iron, Magnesium, Potassium and Phosphorus analyses. The results of the analyses show these maximum values: 97.67±1.15mg/100g, 4.36±0.50mg/100g, 2.93±0.12mg/100g, 109.33±1.15mg/100g and 109.33±1.15mg/100g for Calcium, Iron, Magnesium, Potassium and Phosphorus respectively.

In conclusion, cassava peels which constitute an environmental nuisance have been utilized to produce mushroom. This has popularized the use of this agricultural waste for the cultivation and utilization of mushroom with two fold benefit. Firstly, conversion of this abundance waste to produce mushroom is useful to combat recurrent environmental pollution. Secondly, the mushroom produced served as unconventional mineral rich food sources to supplement other traditional Nigerian diets. This is aimed at combating the problem of macro and micronutrient malnutrition in the society. Hence, cassava peel waste has been turned from waste to wealth

Key words; Mushroom, cassava peel, sawdust, rice bran.
