Effect of growth factors on the production of mycelium-based biofoam

Mycelium-based biofoam has the potential to become an alternative petroleum-polymeric based-foam by utilising fungal mycelium and lignocellulosic material as matrix substrate, respectively. The materials, which were rice husk, sawdust, sugarcane bagasse, is crucial for production of biofoam, tested a substrate Pleurotus ostreatus growth during screening procedure. Three factors varied mycelium-based production: incubation temperature, spawn loading, moisture content. In this study, husk was ideal in compared other fungi. inhibition P. at 30 °C temperature due decay contamination. On hand, varying factor on optimum dry density mycelium–biofoam observed 50% (w/w) content (1.07 g/cm3), while compressive strength 40% loading (1.350 MPa). These results showed that could influence mechanical behaviour material. morphology also through scanning electron microscope. Short highly entangled tube-like structures compact filaments forming seen, responsible lightness characteristic functional group determined using Fourier transform infrared spectrophotometer. A new band proteins lipids detected 1633 cm−1 3280 biofoam. It clearly shows chemical nature feeding changes spectra. Therefore, study highlighted biodegradable promising polymeric foam.
