Method for producing rapidly renewable chitinous material using fungal fruiting bodies and product made thereby
The method of growing a fungal fruiting body requires exposing a mycelium of a desired organism type to environmental conditions sufficient to induce fruiting of fungal primordium in the organism type followed by enclosing the fungal primordium within a mold of a designated shape representing a near net shape volume of a desired final product. The fungal primordium is allowed to grow and fill the mold to form a mass of fungal tissue equivalent in shape to the designated shape of the mold after which the mass of fungal tissue is removed from the mold and dried.
1. Method of growing a fungal fruiting body comprising the steps of
exposing mycelium of a desired organism type to environmental conditions sufficient to induce fruiting of fungal primordium in said organism type;
enclosing said fungal primordium within a mold of a designated shape representing a near net shape volume of a desired final product;
allowing said fungal primordium to grow and fill the mold to form a mass of fungal tissue equivalent in shape to said designated shape of the mold;
removing said mass of fungal tissue from the mold; and
drying said mass of fungal tissue.
2. A method as set forth in claim 1 wherein said step of exposing mycelium of a desired organism type to environmental conditions includes exposing said mycelium to a varying amount of incident light.
3. A method as set forth in claim 2 wherein said step of exposing mycelium of a desired organism type to environmental conditions includes exposing said mycelium to a varying wavelength of incident light.
4. A method as set forth in claim 1 wherein said step of exposing mycelium of a desired organism type to environmental conditions includes exposing said mycelium to carbon dioxide gas.
5. A method as set forth in claim 1 wherein said step of exposing mycelium of a desired organism type to environmental conditions includes exposing said mycelium to variable temperature.
6. A method as set forth in claim 1 wherein said step of exposing mycelium of a desired organism type to environmental conditions includes exposing said mycelium to a relative humidity of from 85% to 90%.
7. A method as set forth in claim 1 further comprising the step of placing aggregate within the mold to allow said fungal primordium to grow about the aggregate to incorporate the aggregate within said mass of fungal tissue.
8. A method of growing a fungal fruiting body comprising the steps of
creating a substrate capable of supporting growth of a desired fungal specie;
inoculating said substrate with said specie;
incubating said inoculated substrate under environmental conditions optimal for the mycelia of said fungal specie to fully colonize said substrate and mature to such a point as to support fruiting body growth;
inducing pinning of said species in said substrate suitable for inducing pinning of at least one fungal primordium in said organism type;
enclosing said fungal primordium within a mold of a designated shape representing a net shape volume of a desired final product; and
allowing said fungal primordium to grow and fill the mold to form a mass of fungal tissue equivalent in shape to said designated shape of the mold.
9. A method as set forth in claim 8 wherein a plurality of fungal primordium are induced to grow and enclosed within the mold.
10. A method as set forth in claim 9 further comprising the steps of removing said mass of fungal tissue from the mold and thereafter drying said mass of fungal tissue.
11. A method as set forth in claim 8 further comprising the step of placing said substrate in a flexible bag of opaque material having at least one orifice therein for growth of said fungal primordium therethrough into the mold.
