The process provides a biofilm including and not limited to cellulose produced by bacteria that can be used as a bio-resin and as a surface application for myceliated and non-myceliated biomaterials.;In one embodiment, the process comprises the steps of obtaining an agricultural substrate; and cohabitating a selected bacteria with a selected fungus in the agricultural substrate for a period of time to allow the bacteria to grow alongside the fungus and to excrete a biofilm from the bacteria into the substrate to provide bio-resin like strengthening compounds to the agricultural substrate.
