ABSTRACT:
Spherical shaped mycelial pellets suitable for use in the biocatalytic conversion of organic compounds are prepared having a rigid spherical core surrounded by a porous webbed layer of structural integrity of a mycelial microorganism. The webbed layer is preferably separated from the core by a substantial void space and is attached to the core by a portion of the mycelium of the microorganism. The core may be composed of a cellulose derivative or agar. The pellets are prepared by forming a solution of a cellulose derivative or agar, mixing spores of a mycelial microorganism with the solution, precipitating the celluose derivative or agar to form beads containing the spores and incubating the beads in a culture medium.
