摘要: The effect of corn oil addition on mycelium growth and polysaccharide productions in the medicinal mushroom Ganoderma lucidum was studied. The results showed that when a level of 2% corn oil was added at the beginning of culture, the biomass and polysaccharide productions reached a maximum of 12.9 and 1.038 g/L, respectively, during 13-day cultivation. The pH variation along with morphology observation in culture provided an indirect inference to the promotional effect of oil addition. Moreover, a curve fitting analysis was carried out to assay the elevated effect on biomass and exopolysaccharide productions in oil added culture. The experimental data of substrates consumption and products formation in culture with oil addition were predicted through the fitting equations obtained in single carbon source culture. The numerical results further clarified the stimulatory effects of oil addition in G. lucidum culture.
