ABSTRACT

Submerged batch and repeated fed-batch cultivation techniques were used for mycelia cultivation and polysaccharide production of the Lingzhi or Reishi medicinal mushroom Ganoderma lucidum. Although most publications use various Asiatic G. lucidum strains, the growth of the strain Ga.l 4 (Biotechnical Faculty Strain Collection, Ljubljana, Slovenia), originally isolated from the Slovenian forest, is much faster. The results between the batch and repeated fed-batch cultivation are compared with the polysaccharide production in batch cultivation. From the aspect of biomass production, the best results were obtained in repeated fed-batch after 44 days, where 12.4 g/L of dry fungal biomass was obtained.
