Modulations in antioxidant properties of button mushroom, Agaricus bisporus , cultivated on selenium-rich wheat straw from the seleniferous belt of Punjab (India) were examined in comparison to the mushrooms cultivated on normal straw. Selenium (Se) uptake by Se-fortified mushrooms (122 ± 1.8 µg/g DW) was significantly higher than control (14 ± 0.7 µg/g DW). The antioxidant activity, as determined by various assays viz., free radical scavenging, metal chelating activity, reduced lipid peroxidation; as well as inhibition of cancer cell proliferation was higher in experimental mushrooms as compared to control. Further analysis of Se rich extracts, using FTIR and MS indicated possible presence of selenoergothioneine-like moiety as an expression of Se uptake by mushrooms. The present study demonstrates the increased anti-oxidant activity in mushrooms cultivativated on Se hyperaccumulated agricultural residues.
