    Biodegradation of Sweet Corn Cob Using Edible Fungi: A Circular Economy Approach
    (Lead City University Ibadan, 2025-12) Adenike Abiola SHOSANYA
    Agricultural wastes (corn cob, rice bran, bagasse) generated from agricultural practices are un-useful and discarded, their accumulation in the environment causes a serious challenge, there is need for eco-friendly waste management solutions which could be achieved through the introduction of the circular economy approach of reducing, re-use and recycling of wastes to produce new valuable products instead of the linear economy where wastes are dumped on the road, in water ways, or burned leading to environmental degradation and loss of valuable organic matter. Agricultural wastes rich in lignocellulosic materials are valueless and indigestible for animals but could be degraded by the lignocellulolytic enzymes in edible fungi. The study investigated the biodegradability of edible fungi (Pleurotus pulmonarius, Pleurotus ostreatus and Pleurotus citrinopleatus) on sweet corn cob to produce animal feed and protein-rich mushrooms. The parameters analyzed in the study include; rate and extent of biodegradation, lineal mycelial growth rate, analysis of chemical composition, mineral and vitamin content of degraded and undegraded sweet cob. Data obtained were analyzed using one way ANOVA and Excel Spreadsheet Statistical Package in accordance with AOAC official method in complete randomized timeline (988.05). Result shows that the weight of the substrate reduced, mycelial growth rate increased after biodegradation. Cellulose, crude fiber, hemicellulose, ADF, NDF and ether extract reduced due to enzymatic actions on the corn cob. Crude ash, crude protein increased as a result of the reduction in the lignocellulosic content of the sweetcorn cob. Macro minerals; Calcium, Phosphorus, Magnesium increased while Potassium reduced. Micro minerals; Iron, Manganese, Zinc all increased. Fungal colonization markedly increased the level of vitamin content of the substrate. This research shows that fungi (Pleurotus spp) are good biodegraders, turning wastes to valuable products in a circular economy enhancing waste management, creating economic opportunities promoting food security and environmental sustainability.

    Nutritional Content and Bio-Degradation of Sweet Corn Leaves Using Edible Fungi (Pleurotus pulmonarius)
    (Lead City University, 2022-12) Adenike Abiola SHOSANYA
    The need to feed ever-increasing human population created awareness for increased agricultural production thus leading to increased agricultural waste generation. These wastes generated in many developing countries are not properly managed, utilized or under - utilized which constitute serious health threat to human and animals in the environment through environmental pollution resulting into environmental hazards. Agro wastes are rich in nutrient composition such as protein, minerals; consequently they ought to be considered as “raw material” instead of “waste”. Using them as raw materials can help to recycle waste and make the environment eco –friendly through solid state fermentation (SSF) which produces secondary metabolites and essential enzymes and serves as potential substrate to produce value – added products. Biological degradation for both economic and ecological reasons has become the popular alternative for the treatment of agro wastes .Wastes from agricultural residues are used as bioremediation agents, biofuel and bio - control agents through microbial processing which has brought tremendous benefit to agricultural management and eco - system. This study determined the phytochemicals, minerals and vitamins present in sweetcorn leaves and the effect of biodegradation on the leaves. Sweetcorn leaves were collected, dried and milled .Crude protein analysis was carried out on the milled sample using the Association of Official Analytical Chemists (AOAC) procedure. The crude protein value was 40.82% while the crude fiber was 25.1. The fungi (Pleurotus plumonarious) was introduced into the specimen bottle and kept in the incubator at room temperature for 7, 14, 21 and 40 days, the result was recorded Keywords; Agro waste, Solid state fermentation, Substrate, Ecosystem, Biological degradation, Bioremediation, Metabolites.
