Ganoderma lucidum, a renowned fungus for its medicinal properties and content of bioactive compounds include polysaccharides, triterpenoids, immune modulatory proteins, among others; it has generated a significant increase and interest in its production. Most species of fungi respond and adapt to various environmental signal including light, which affects it not only in productivity, but also in quality and quantity to be closely related to the fruiting bodies. Therefore, the objective of this study was evaluating the biological efficiency (EB) and the rate of production (TP) as production parameters of the solid culture of Ganoderma lucidum at under irradiation of the substrate with light emitting diodes blue (LED) with two levels of photo-stimulation constant 12 and 24 h during all steps of culture to induce mycelial growth and the formation of fruiting bodies. Conventional parameters were applied to stimulate the growth and development of the fungus in the stages of production. For the formulation of substrates agro-industrial waste and lignocellulosic materials were used. The diameter of the fruiting bodies under blue light treatments was higher than those exposed to white fluorescent light (control). The results show that the cultivation of Ganoderma lucidum with exposure to blue light is useful for induction of fruiting bodies of high quality, achieving a reduction of the period of fermentation in 16 days for the photo-stimulation of 24 h with EB of 28,04% and TP of 0,64.
