Optimization of Rhizopus Sp. Growth Media for Biofoam Manufacture: Effect of Temperature and Substrate Composition

Biofoam is a biodegradable material that can substitute the use of styrofoam. be produced from Rhizopus sp. mycelia. In development biofoam fungal mycelia, mycelia act as reinforcement or binder for substrate (media) because grow and spread throughout substrate. Therefore, optimization growth medium by varying composition incubation temperature had been done in this research. The consisted sugarcane trash (particle size 20, 40, 60 mesh), starch (soybean, sago, rice), CaCO3, distilled water. inoculum mixed with was incubated at certain temperatures (29 35°C) 7 days. FESEM-EDS analysis starches showed soybean has more nutrients than rice sago starch. optimum TK 1, which consists 20 mesh trash, flour, water an 29°C. That grew well evenly distributed 1 average length ± 1.3 cm. distribution media also seen morphology using Kayence digital microscope.The suitable optimize
