ABSTRACT

The mycelial growth of the Reishi medicinal mushroom (Ganoderma lucidum) increased with the increase of the wheat bran rate added to the basal sawdust medium up to 20% supplementation but leveled off thereafter. G. lucidum produced 11 extracellular degradative enzymes: cellulases (filter paperase, endoglucanase, avicelase, cellulase azure, β-glucosidase), lignin peroxidase, Mn-dependent peroxidase, laccase, xylanase, amylase, and proteinase. The significant increase in the activities of the extracellular degradative enzymes in G. lucidum occurred in the wheat-bran-enriched basal sawdust medium.
