Abstract:

Effects of water and ethanol extracts of 10 Chinese medicines, such as Astragalus membranaceus, Coix lachryma-jobi, etc ., on biomass and exopolysaccharide of Ganoderma lucidum were studied by submerged culture. The results showed: water extracts of all medicines can improve the culture of G. lucidum except of A. membranaceus , ethanol extracts of C. lachryma-jobi, Dioscorea opposita, Codonopsis pilosula , and Achyranthes bidentata (<187.5g Medicine/L substrate) can also increase the biomass of G. lucidum , but the ethanol extracts of Angelica sinensis, Dendrobium nobile check the growth of G. lucidum. The production of exopolysa- ccharide can be improved by all the Chinese medicines and their dosage used in this experiment, Although A. sinensis, D. Nobile check the growth of G. lucidum , they could stimulate the secretion of exopolysa- ccharide in lower dosage. It is concluded that some Chinese medicines, such as C. lachryma-jobi, D. opposita, C. pilosula, etc. can be processed by the fermentation of G. lucidum, and bio-active compound can be produced by adding appropriate Chinese medicine in the substrate to culture G. lucidum.
