With an aim to explore the productivity and quality of the fruiting body of culinary-medicinal golden oyster mushroom Pleurotus citrinopileatus, the carbon dioxide (CO2) concentration of the ambient atmosphere was adjusted and a light-emitting diode panel was used to illuminate the colonized mycelium at different wavelengths. Biological efficiency and yield were higher at CO2 levels of 0.05 and 0.1% than other tested CO2 levels, and the mature fruiting body showed the highest yellow value at a CO2 level of 0.1% (of all tested CO2 levels). The highest biological efficiency and yield was obtained at the 720-nm wavelength. The ergosterol content of the pileus of the fruiting body was higher than that of the stipe in any flush time at a 720-nm wavelength of light and a CO2 concentration of 0.1%. The decreased percentages of cellulose and lignin at the appearance of primordia were larger than those of mycelial growth duration. The fruiting quality of P. citrinopileatus might thus be enhanced by 720-nm illumination and an atmosphere with a CO2 concentration of 0.1 to 0.15%.
