ABSTRACT
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 20°C 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 ostrearus 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
