COMPOSITION AND METHOD FOR SUBMERGED CULTURING OF EDIBLE MUSHROOM

摘要

The invention provides a culture medium composition and method for submerged culturing of mushroom. The mushroom is an edible mushroom, which in one embodiment is of the genus Calocybe. The culture medium composition comprises carbon source, nitrogen source, metal cations, trace metals, suitable anions associated with the metal cations. The method comprises preparing a mycelium from a spawn of the mushroom grown on a substrate, inoculating a growth medium with the mycelium to provide a inoculated growth medium, incubating the inoculated growth medium to provide a seed culture, and incubating the seed culture in a culture medium composition to provide the biomass of edible mushroom. By processing the culture medium and biomass either separately or in combination, industrially important compounds like amino acids, secondary metabolites, polysaccharides, etc. can be extracted and used for various purposes.
