ABSTRACT

Ganoderma lucidum is a well-known medicinal mushroom species in which polysaccharides are one of the major sources of biological activity. The species was considered as a species-complex due to significant variations in morphological, biochemical, and genetic features among populations with a worldwide distribution. This fact was the basis for setting the aim of this research: to study intraspecific diversity in polysaccharide production and intracellular sugar composition among selected G. lucidum strains. The presence of intraspecific diversity among 10 G. lucidum strains, from different areas worldwide, was noted. Values of produced mycelia biomass and intracellular polysaccharides were found in wide ranges (3.1−28.2 g L−1 and 20.0−53.3 mg g−1, respectively), while differences in extracellular polysaccharide amounts were minor (0.2−1.5 mg mL−1). The significant quantitative and qualitative differences in intracellular sugar composition were noted. Glucose was the predominant sugar in almost all strains except one (HAI 447), where sucrose was dominant. The potential of polysaccharide production and intracellular sugar composition could be one more taxonomic criterion for strain characterization within G. lucidum. The differences in intracellular sugar composition and proportions could be reflected in features of produced polysaccharides and also in their biological activities.
