Abstract

Fungi are a highly relevant research subject because of their biodegrading ability and bioconversion capacity. Since they secrete enzymes and organic acids in an extracellular environment, fungi chemically degrade complex molecules which may be employed in the treatment of agricultural and industrial residues. Ganoderma lucidum is currently being studied worldwide, mainly in Eastern countries, due to its numerous medicinal properties. Popularly known as Reishi, its active chemical ingredients are being researched for treatments on cancer, allergies, hypertension and others, and even for the prevention of these diseases. Few data exist on the submerged cultivation of Ganoderma lucidum. It is, therefore, highly interesting to investigate the conditions necessary to optimize the production of pharmacological and biotechnological compounds produced by this fungus. Current research assesses alternative sources of carbon and nutrients derived from different liquid cultures, or rather, dextrose, cane-sugar molasses and iodine (a byproduct of sugar-cane processing) in the production of biomass and exopolysaccharides (EPSs) by G. lucidum. Alternative culture media employed in present investigation are suitable for the production of biomass and EPSs by G. lucidum. Biomass and EPSs production are favored when the byproduct of cane-processing (iodine) at a concentration of 30 g/L-1 is used.
