SUMMARY OF RESEARCH ACTIVITIES

Cultivation of Edible Mushrooms

Edible mushroom are eaten worldwide. They are high in protein but low in carbohydrates. Exotic edible mushrooms like Agaricus bisporus are imported into Nigeria at high costs. Production of such mushrooms is very expensive because of climatic differences. Prof. Okwujiako and co-workers concern their research with domestication/cultivation of tropical mushrooms for public consumption.

Mycoremediation

Pollution from petroleum and other chemicals has become a major environmental concern. Remediation methods such as landfilling and use of chemicals are unwieldy and expensive.  Biotechnological methods have focused much on the use of bacteria. However, fungi, especially white-rot basidiomycetous fungi now hold more promise in ameliorating polluted environments. White-rot fungi are lignin-degrading and, because recalcitrant pollutants have a structural resemblance to lignin, these fungi have the ability to metabolize the pollutants. Prof. Okwujiako’s team is investigating the use of white-rot fungi in mycoremediation.

Nutraceuticals/Pharmaceuticals

Edible mushrooms such as Pleurotus spp and Lientinulus edodes are enjoyed not only for their culinary delicacy but also as health foods. They impart general wellness to consumers and are regarded as nutraceuticals /pharmaceuticals. Some of them possess antioxidant, hypoglycemic, hyperlipidemic, immunoregulatory and anti-tumour properties arising from the bio-active substances contained in them. Prof. Okwujiako and his colleagues are investigating the health benefits provided by some medicinal mushrooms.
