Abstract :

 Problem of disposal of solid wastes such as agro-industrial wastes and other pollutants is a major concern in the developing countries of the world. In this study, emphases were focused on conversion of agricultural wastes such as rice straw and sorghum stalk into substrates of utilizable products (wastes to wealth). These wastes were subjected to solid state fermentation for 40 days using Pleurotus florida (a white rot fungus from Nigeria). Nutritional analyses were carried out on both fermented and non fermented substrates (control).Nutrients in the biodegraded samples were observed to be increasing with the days of incubation. The results also showed that fermented rice straw and sorghum stalk were richer in nutrients than none fermented substrates. It was also observed that the biodegraded samples enhanced in-vitro digestibility in the tested animals. Biologically treated sorghum stalk were found be richer in nutrients than the treated rice straw. The implications of these observations were discussed.
