Abstract :Mineral elements are very important in the metabolic processes of living things; hence their absence often results to deficiency diseases. This study reports the effects of selenium fortification on biological efficiency and the distribution of essential and non-essential amino acids in P. ostreatus. Viable spawn of P. ostreatus was inoculated into substrate spiced with Se while the control was P. ostreatus cultivated on substrate without Se. The biological efficiency was calculated using standard method while the amino acid content of the Se fortified and non fortified P. ostreatus was analysed using Applied Biosystems PTH amino acid analyzer. The biological efficiency (31.3%) of Se fortified P. ostreatus was lower compared to P. ostreatus not fortified with Se (43%). Moreover, there was reduction in essential amino acids in P. ostreatus fortified with Se, except Valine (50.0mg/100g) that was higher in Se fortified P. ostreatus. Generally, the percentage nitrogen in Se fortified P. ostreatus (4.79%) was slightly lower than what was obtained in non-selenium fortified P. ostreatus (5.05%). Data gathered from this study revealed that Se fortification markedly affects the biological efficiency, quantities and distribution of essential and non-essential amino acids in P. ostreatus.
