Abstract
When Pleurotus tuber-regium was cultivated on cotton waste , rice straw, cocoyam peels and sawdusts of Mansonia altissima,
Boscia angustifolia and Khaya ivorensis, the highest crude protein, crude fat and carbohydrate contents in sporophores were
29.4 (M. altissima) , 1.4 (rice straw) and 61.3% (cocoyam peels), respectively. Sporophores produced on rice straw had the greatest
energy value and those on B. angustifolia the least i.e. 3147.6 and1709.1 kcal g-1 substrates, respectively. The greatest degradation of the
components of the substrates as a result of the cultivation was 62.4 and 71.5% for cellulose and hemicellulose in cotton wastes and 60.2%
for lignin in K. ivorensis , with the greatest reduction in energy value of the substrate being 2667.9 kcal g-1 substrate in K. ivorensis. There
was no correlation between the extent of the degradation of these components and the yield of of sporophores, while the energy recovery
of substrate in the mushroom was highest for cocoyam peels and least for sawdust of B. angustifolia, 3.7 and 0.5%, respectively.
