The change tendencies of acidic proteinase activity,neutral proteinase activity, amylase activity, endo-glucanase activity, exo-glucanase activity and β -glucosidase activity were studied during liquid-state fermentation of Ganoderma lucidum by using selenium-enriched soybean emulsion as medium. The results showed that the acidic proteinase activity, amylase activity, endo-glucanase activity, exo-glucanase activity and β -glucosidase activity increased during liquid-state fermentation of Ganoderma lucidum. The enzylne activity reached the highest degree in 132 h in fermentation, the acidic proteinase activity 9.87 U/mL, amylase activity 0.87 U/mL, endo-glucanase activity 0.95 U/mL, exo-glucanase activity 1.07 U/mL, β-glucosidase activity 1.85 U/mL. The neutral proteinase activity reached the highest degree 5.35 U/mL in 108 h.
