In order to determine the possibility of artificial cultivation of Ganoderma lucidum, a study was carried out to optimize the medium composition used for bed culture. Sawdust spawn of medium composition for optimal growth was found to be the combination of 75% oak-sawdust, 10% cotton-seed meal, and 15% beet pulp. The optimal conditions for the formation of fruiting bodies were shown to be a temperature of 28–30oC, light intensity of 1,000–1,500 lux, and CO2 concentration of 1%.
