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3.5×107 CFU/mL,原生质体再生率达到1.4%。

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
