Influence of Different Environmental Conditions on Schizophyllum commune Spawn Cultivation

Abstract ―​

Schizophyllum commune (Split-gill mushroom) is a wild mushroom utilized as food, especially in the Philippines. In this study, the optimal environmental conditions for the mycelial growth of S. commune spawn were studied to develop a protocol for efficient spawn cultivation. Mycelial increment and density of S. commune incubated under varying illumination (24hrs light, 24hrs darkness, and 12hrs light-dark cycle) and temperature (32-36oC, 28-32oC, and 16-23oC) conditions were evaluated. Results showed that S. commune spawn cultures can grow vigorously in any of the illumination conditions. However, an equal amount of light and dark cycles significantly improved the mycelial density of S. commune spawn. The result also revealed that incubating under 16-23oC significantly increased S. commune mycelial increment at 0.92 ±0.03 cm day-1. Moreover, spawn incubated under 28-32oC significantly improved the mycelial density of S. commune.
