Abstract: The optimal conditions for preparing protoplast from lywallzyme by cultured monocaryon mycelia of Pleurotus geesterani were investigated via single factor and orthogonal array design. The results showed:the yield of protoplast and regeneration rate of protoplast reached 3.5×107 CFU/mL and 1.4% respectively,under the conditions of 8 days mycelium in the enzyme solution of 1.6% lywallzyme digested for 160 min at temperature of 29℃ with 0.6 mol/L mannitol +10 mmol/L Tris-HCl as osmotic pressure stabilizer.

Key words: Pleurotus geesterani, monocaryon mycelia, protoplast, lywallzyme
