By fortifying growing sets with Lithium dioxide, this study aimed to increase the Lithium concentration in mushrooms. Results showed a significant increase in Lithium content in mushrooms at the 100 mg per kg dry weight level, reaching 440 times higher than the control group, with minimal impact on the accumulation of other trace mineral constituents.
In an attempt to enrich the fruiting bodies with Lithium (Li), this study cultivated mushrooms using growing sets that were fortified with Li2O at 1.0, 5.0, 10, 50, 100 and 500 mg center dot kg(-1) dw. Compost fortification up to 100 mg center dot kg(-1) dw induced a dose-dependent increase in Li accumulation with resulting median mushroom concentrations of 2.0, 8.6, 16, 29 and 38 mg center dot kg(-1) dw, respectively, relative to the unfortified control at 0.087 mg center dot kg(-1) dw. The dose dependency appears to level off as Li2O addition approaches 100 mg center dot kg(-1), suggesting that there is a limit to the ability of the species to accumulate/tolerate Li. Mushrooms did not grow at the 500 mg center dot kg(-1) dw fortification level. At the highest viable level of fortification (100 mg center dot kg(-1) dw), the fruiting bodies were around 440-fold richer in Li content than the control mushrooms. Additionally, the fortification at all levels up to 100 mg center dot kg(-1) dw showed very low, if any, effect on the co-accumulation of the other, studied trace mineral constituents, with concentrations occurring at the lower range of those reported for commercial A. bisporus mushrooms.
