Method of growing mycological biomaterials
A growth medium formed as an inoculum including a preselected fungus and a nutrient material capable of being digested by the fungus is placed in or on a tool formed of a material capable of being at least partially consumed by the fungus. The tool may define a cavity of predetermined shape for the growth medium or the tool may form a scaffolding on which the growth medium grows into the final product taking on the shape of the tool.
1. A process of growing a mycological biomaterial comprising the steps of
forming a growth medium including discrete particles, an inoculum including a preselected fungus and a nutrient material capable of being digested by said fungus;
placing said growth medium in a tool formed of a material capable of being consumed by said fungus and defining a cavity of predetermined shape for said growth medium; and
growing said fungus on and through said growth medium in said cavity of said tool to form a product corresponding to said predetermined shape of said cavity with said fungus consuming at least some of said tool.
2. A process as set forth in claim 1 wherein said tool is fully consumed by said fungus into said product.
3. A process as set forth in claim 2 wherein said tool is made of at least one of paper pulp, bamboo, papier-mâché, starches, plant seeds, alginates, gelatin, plant fibers, paper fibers, burlap, plant-derived nonwovens and wovens, and pre-grown mycelium sheets.
4. A process as set forth in claim 1 wherein said tool is partially consumed by said fungus into said product.
5. A process as set forth in claim 4 wherein said tool is made of at least one of synthetic fibers, glass fibers, carbon fibers, nylon fibers and plastic mesh materials.
6. A process as set forth in claim 1 wherein said tool is formed by creating a slurry of cellulose fibers, hemicellulose, water and nutrients; and vacuum pressing the slurry on a buck of a predetermined form to mold said tool.
