摘要:

以刺芹侧耳菌丝为底物,利用溶壁酶进行原生质体制备,考察酶解因素对原生质体制备的影响。采用单因素试验和正交试验确定最佳酶解条件。结果表明:溶壁酶的最适酶解条件为最适酶解温度30℃、pH6.0、底物质量浓度133mg/mL、酶质量分数1.0%、酶解时间2.5h,在此条件下,刺芹侧耳原生质体的产量为6.34 ×107 个/mL。

Abstract:

The optimal conditions for the lywallzyme hydrolysis of the cultured mycelia of Pleurotus eryngii for protoplast production were investigated by single factor and orthogonal array design methods. Results showed that the optimal values of hydrolysis conditions were as follows: substrate concentration 133 mg/mL, enzyme dosage 1.0% and pH 6.0 for a hydrolysis duration of 2.5 h at 30 ℃. The hydrolysate obtained under such conditions exhibited a protoplast density of up to 6.34 × 107 cells/mL.

Key words: lywallzyme, Pleurotus eryngii, protoplasts, enzymolysis conditions, orthogonal array design
