Abstract: An abrasion resistant finish for a fungal material, the finishing comprising an optimum quantity biodegradable polylactic acid plastic (PLA) dispersed in water to produce a PLA mixture. When the PLA mixture is applied to the fungal material, water carries the PLA deeply into the matrix of the fungal hyphae to a depth at least 2 N/10 mm or 1% of the thickness of the fungal material, whichever is greater. The finish fortifies the hyphal structure as the water evaporates and creates a PLA coating on the fungal material with improved abrasion resistance and water resistance.

Abstract: A mycelium growth bed for optimal production of pure mycelium or a pure mycelium composite with controlled or predictable properties, the bed comprising a tray, a conveying platform, a permeable membrane, a substrate, a porous material and a lid.

The system provides a configuration having a substrate weight to surrounding space volume ratio between 0.5 and 5.0 g/cc, an air volume (surrounding space) to substrate volume between 0.01 and 1.0, and an air volume (surrounding space) to substrate area is between 0.5 and 5 cc/cm, wherein the CO2 concentration is held above 3%, the relative humidity is held above 40% and the O2 concentration is held below 20% in steady state conditions to produce leather-like mycelium without fruiting bodies.

Abstract: A method for reducing and determining coefficient of friction of a mycelium for improving a plurality of mechanical properties of the mycelium. In the method, a first mycelium layer is contacted with an abrasive and pressure apparatus for smoothing and altering a microstructure of the mycelium. The smoothing of the mycelium microstructure reduces the coefficient of friction of the mycelium thereby enhancing the abrasion resistance of the mycelium. The coefficient of friction of the mycelium surface reduced through smoothing of the mycelium surface is determined utilizing a tilt angle mechanism.

Abstract: A flexible fungal composite with an engineered and/or improved mechanical properties such as tear strength, tensile strength and resistance to separation. The fungal composite is generated by embedding a second material within a fungal matrix. The tear strength of the fungal composite is greater than the tear strength of the fungal matrix.
