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 physico-chemical, 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.

By seeding fungus on top of industry residues, a mycelium can grow and form a compacted network structure, producing a material whose properties can be quite similar to polystyrene. However, depending on the source used, it may not develop due to lack of optimal fungal nutrients. In such case, peach palm residues can be a potential alternative. To test this hypothesis, this work evaluated the effect of using peach palm sheaths for mycelium growth of Lentinula edodes. They were also supplemented with cassava bran and varied sources of nitrogen – ammonium sulphate, potassium nitrate and soy flour – in order to analyse its effects to their properties, enzymatic activities and mycelium growth; at 12 and 20 days of cultivation. A well-formed composite occurred for pure soy flour, whose properties were tested as a compressed and non-compressed material, exhibiting acceptable values and demonstrates that this residue can be a potential alternative.
