Abstract
The mycelial growth performance on 10 different indigenous culture media 9ricebran decoction gulaman (RBDG), oatmeal decoction gulaman (OMDG), soybean decoction gulaman (SBDG), rice (CL-1 aromatic rice) decoction gulaman (RDG), coconut water decoction gulaman (CWDG), sorghum decoction gulaman (SDG), cornmeal decoction gulaman (CMDG), baguio beans decoction gulaman (BBDG), mungbean decoction gulaman (MBDG) and taro decoction gulaman (TDG) and the optimum physical factors (pH, temperature, aeration and illumination) of P. giganteus Bayombong Nueva Vizcaya (BNV) strain were investigated in this study. In the desire to develop production technology for this mushroom, indigenous culture media from the crops that have cheaper cost were formulated. Results of the study revealed that RBDG was the most favorable culture media for mycelial growth of P. giganteus. BNV strain showing signs of higher mecelial density as well as higher mycelial diametercompared to other culture media. In terms of physical factors, wide range of pH were suitable for the mycelial growth, room temperature (29°C) was the most favorable condition for the mycelial growth. Also, unsealed condition was the optimum for the mycelial growth and lastly, complete darkness showed the highest mycelial diameter. Incubation period of P. giganteus BNV strain had been shortened.
