Antioxidant properties of different edible mushroom species and increased bioconversion efficiency of Pleurotus eryngii using locally available casing materials

► Pleurotus eryngii possessed higher total phenolics, RSA on DPPH and growth/day. ► Higher ascorbic acid and chelating activity was found in Pleurotus citrinopileatus. ► Based on AHC, studied edible mushroom species were fall into two clusters. ► Enhanced BE of P. eryngii was achieved using spent compost casing overlay.
