Nutritional properties of straw mushrooms grown on plantain leaves, maize husk and waste cotton were investigated. Aim: The aim of this study was to recommend these agro-wastes for mushroom production by farmers instead of relying solely on seasonal wild hunting, and to promote consumption of the mushroom. Method: Ten percent (10%) of the mushrooms spawn was used to inoculate 500 g of each substrate in plastic baskets. Mushrooms were harvested after twenty days of incubation followed by proximate analysis of the fruiting bodies. Results: Results indicated that the fruiting bodies harvested from the substrates varied significantly (P Conclusion: These agro wastes are recommended for production of V. volvacea.展开更多

This study was designed to evaluate the remnant hydrocarbon in the sporophore (fruiting body) of?Pleurotuspulmonarius?and to assess its suitability for human consumption. Method: The mycelia of the mushroom were used to inoculate Spent Engine Oil (SEO, 10% (v/w)) polluted soil. After four weeks of incubation, fruiting bodies growing on the polluted soil were analyzed for remnant hydrocarbon profile. Results: Results showed that total Polycyclic Aromatic Hydrocarbon (PAH) was 10 mg/kg and Aliphatic Hydrocarbon (AH) was 23 mg/kg. The hydrocarbon profile indicated some AH and PAH were within the non-cancer reference dose while a few others were above the non-cancer daily reference dose range. Conclusion: The detection of some hydrocarbon profile above the non-cancer daily reference dose makes the test-mushroom used for bioremediation not safe for human consumption. This underscores the need for caution in consuming mushrooms found in oil polluted environment.展开更多
