Factors affecting the production of mushroom mycelium from Agaricus bisporus, Pleurotus ostreatus and
Pholiota aegerita grown in mango stone infusion for 7 days were studied. The optimum conditions enhancing the
economic coefficient (EC) of mushroom mycelium were 25, 30 and 200C for incubation temperature, 4.0, 4.5 and 5.5
for pH values, 300 r.p.m. for shaking rate and 25 : 1 for C/N ratio in case of Agaricus bisporus, Pleurotus ostreatus
and Pholiota aegerita with high EC of 66.8, 51.9 and 63.9, respectively. In comparison under these optimum conditions,
molasses media (as control) reflected lowered EC than that of mango stone infusion. The dry mycelium of A.
bisporus showed a higher protein and fat contents than Pleurotus ostreatus and Pholiota aegerita. Inorganic elements,
Mg, Ca, Na, K, Cu, Fe, Mn, Zn, Pb and Cd were also detected.
