This study was carried out to develop bottle culture method of Grifola frondosa . To find out the optimum medium composition of G. frondosa , physicochemical conditions of various media and those cultural properties were investigated. The T4 formulation(80:10:10 mixing ratio of oak sawdust, dried bean-curd refuse and corn husk) showed a shorter time to complete the crop cycle and a higher yields than control. Its physicochemical conditions were 5.4 of pH, 2.4% of crude oil contents, 54.1% of total carbon, 1.61% of total nitrogen, 34 of C/ N ratio, 74.3% of porosity and 0.26g/cm3 of bulk density. Development of optimum medium for bottle cultivation of G. frondosa would benefit from increased production efficiency of G. frondosa mushrooms and be commercial potential.
