  • Fungal inoculum preparation
    Patent number: 5786188
    Abstract: A fungal inoculum for bioaugmentation of soils contaminated with hazardous compounds or spawn for use in the edible mushroom industry is disclosed. A mechanically pelleted substrate that contains both structural and nutritive components forms the core of the fungal inoculum. The pelleted substrate core is coated with a hydrophilic material in which fungal propagules are dispersed. The biological potential of the fungal inocula can be enhanced by formulating the material composition of fungal inocula to meet the specific requirements of a particular fungus.
