Abstract:

The phenomenon of autolysis is widespread among various kinds of microbes. However, there is hitherto no report on the autolysis of Pleurotus tuber-regium (Fr.) Sing. Liquid fermentation method was applied to culture the Pleurotus tuber-regium (Fr.) Sing mycelia and the effects of temperature, pH, osmotic pressure and oxygen supply on the autolysis of Pleurotus tuber-regium (Fr.) Sing mycelium were examined. The results indicated that the optimal conditions for the mycelium autolysis were 40℃, pH 9.0, 3-4%NaCl and anaerobic fermentation. This study provides the basis on which the further investigation of the Pleurotus tuber-regium (Fr.) Sing mycelium autolysis mechanism can be conducted.
