The polysaccharide has been known to have an antitumor activity, which were extracted from the fruiting bodies, mycelia, and culture broths of Agaricus blazei. For the cell growth and the polysaccharide production, the optimal medium contained 8% glucose, 2% yeast extract, 0.1% $MgSO_4{\cdot}7H_2O$, 0.2% $KH_2PO_4$, 0.2% $CaCl_2{\cdot}2H_2O$ and 0.2% $MnSO_4{\cdot}5H_2O$. When 0.2% of glutamic acid was added at 4day, the cell concentration was 13.5 g/L and the polysaccharide production was 9.9 g/L, respectively.
