摘　　要：以秀珍菇单核菌丝为材料,用溶壁酶进行原生质体的制备,考察各因素对原生质体产量的影响,用单因素试验和正交试验确定最佳条件。结果表明,菌龄为8 d菌丝体,0.6 mol/L甘露醇+10 mmol/L Tris-HCl为稳渗剂,酶解温度29℃、酶浓度1.6%的条件下酶解160 min。原生质体产量达到3.5×10~7 CFU/m L,原生质体再生率达到1.4%。The optimal conditions for preparing protoplast from lywallzyme by cultured monocaryon mycelia of Pleurotus geesterani wereinvestigated via single factor and orthogonal array design. The results showed ：the yield of protoplast and regeneration rate of protoplast reached3.5×10-7 CFU/m L 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.
