“…Such plant species should be selected to save the strain life. The most known substrates for the production of mycelium-based materials are wood chips [ 30 , 32 , 66 ], sawdust, straw [ 4 , 8 , 9 , 33 , 71 ], coconut powder [ 72 ], garden waste [ 14 ], and bagasse [ 4 ]. These substrates are selected due to their compatibility for fungal growth and their lignocellulosic content.…”

“…In addition, straw and bagasse have softer particle properties than sawdust, so the fungi can utilize nutrients easily from soft substrates than hard substrate according to [ 32 ]. To enhance the nutritional content, different supplements such as wheat bran [ 8 ]and rice bran and different agricultural straw [ 72 ] are mixed. Table 2 shows different mycelium-based materials with various strains, supplements, and substrates.…”

Because of the alarming rate of human population growth, technological improvement should be needed to save the environment from pollution. The practice of business as usual on material production is not creating a circular economy. The circular economy refers to an economic model whose objective is to produce goods and services sustainably, by limiting the consumption and waste of resources (raw materials, water, and energy). Fungal-based composites are the recently implemented technology that fulfills the concept of the circular economy. It is made with the complex of fungi mycelium and organic substrates by using fungal mycelium as natural adhesive materials. The quality of the composite depends on both types of fungi and substrate. To ensure the physicochemical property of the fabricated composite, mycelium morphology, bimolecular content, density, compressive strength, thermal stability, and hydrophobicity were determined. This composite is proven to be used for different applications such as packaging, architectural designs, walls, and insulation. It also has unique features in terms of low cost, low emission, and recyclable.

Mycelium-Based Composites in Art, Architecture, and Interior Design: A Review

et al. 2021

Mycelium-based composites (MBCs) have attracted growing attention due to their role in the development of eco-design methods. We concurrently analysed scientific publications, patent documents, and results of our own feasibility studies to identify the current design issues and technologies used. A literature inquiry in scientific and patent databases (WoS, Scopus, The Lens, Google Patents) pointed to 92 scientific publications and 212 patent documents. As a part of our own technological experiments, we have created several prototype products used in architectural interior design. Following the synthesis, these sources of knowledge can be concluded: 1. MBCs are inexpensive in production, ecological, and offer a high artistic value. Their weaknesses are insufficient load capacity, unfavourable water affinity, and unknown reliability. 2. The scientific literature shows that the material parameters of MBCs can be adjusted to certain needs, but there are almost infinite combinations: properties of the input biomaterials, characteristics of the fungi species, and possible parameters during the growth and subsequent processing of the MBCs. 3. The patent documents show the need for development: an effective method to increase the density and the search for technologies to obtain a more homogeneous internal structure of the composite material. 4. Our own experiments with the production of various everyday objects indicate that some disadvantages of MBCs can be considered advantages. Such an unexpected advantage is the interesting surface texture resulting from the natural inhomogeneity of the internal structure of MBCs, which can be controlled to some extent.

“…So far only one study have reported the usage of shiitake as a an effective mycelium-based material, using coconut powder with wheat bran as substrate, on the effect of fungi growth and mechanical properties (Matos et al 2019). Therefore, this work investigates the effect of solid-state fermentation from L. edodes on peach-palm sheath bres using three different nutrient growing source treatments and evaluates the number of enzymes produced and their properties when a mycelium-based composite is produced with the best formulation.…”

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 – in order 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, that 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. edod es to grow having lower enzyme activities for a well-developed composite; whereas higher activities were seen for a weakly developed material. and this material demonstrate 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
