Effect of Nitrogen Sources and Illumination Conditions on Ganoderma lucidum Submerged Culture

The research was conducted to select the nitrogen sources and suitable light condition during Ganoderma lucidum submerged culture (isolated in Vietnam). results showed that organic is more than inorganic for growth synthesis of fungal polysaccharides. amounts incellular polysaccharide exopolysaccharide this strain highest when combined 7.5 g/L yeast extract 2.5 peptone. affected on size, shape color DL cells culture. Under optimum sources, biomass, IPS EPS content were 13.90 ± 0.27 g DW/L, 15.33 0.97 mg/100mg DW 2349.76 46.94 mg/L, respectively.
