Conteúdo: 	By seeding fungus on top of industry residues, a mycelium can grow and form a compact network structure; however, it may not develop due to lack of optimal nutrients from the substrate. Consequently, peach-palm residues can be a potential alternative; so, to test this hypothesis, this work evaluates the effect of peach-palm residues as substrate for the growth of mycelium based on Lentinula edodes. They were also supplemented with cassava bran and various sources of nitrogen-ammonium sulphate, potassium nitrate, and soy flour—to analyse its effects on its physicochemical, enzymatic activities, and thermal and mechanical properties of the final composite at 12 and 20 days of cultivation. This mycelium was able to grow at optimum source treatment conditions, which depends on the ratio of Carbon to Nitrogen, within only 12 days of inoculation. Furthermore, the enzyme activities directly correlate with the mycelium growth with optimum conditions of pH, water activity, and moisture for L. edodes to grow having lower enzyme activities for a well-developed composite; whereas higher activities were seen for a weakly developed material, and this material demonstrates mechanical and thermal properties similar to common mycelium-based composites. Therefore, this work demonstrates that peach-palm residues can be a potential alternative for mycelium-based composite.
