The use of Li2O fortified growing compost to enhance lithiation in white Agaricus bisporus mushrooms: Li uptake and co-accumulation of other trace elements

Abstract In an attempt to enrich the fruiting bodies with Lithium (Li), this study cultivated mushrooms using growing sets that were fortified Li 2 O at 1.0, 5.0, 10, 50, 100 and 500 mg·kg ?1 dw. Compost fortification up dw induced a dose-dependent increase in accumulation resulting median mushroom concentrations of 2.0, 8.6, 16, 29 38 dw, respectively, relative unfortified control 0.087 The dose dependency appears level off as addition approaches , suggesting there is limit ability species accumulate/tolerate Li. Mushrooms did not grow level. At highest viable (100 dw), around 440-fold richer content than mushrooms. Additionally, all levels showed very low, if any, effect on co-accumulation other, studied trace mineral constituents, occurring lower range those reported for commercial A. bisporus
