摘要
本文详细地探讨了杏鲍菇原生质体制备条件。结果表明:用0.6mol/L的甘露醇配制成质量比为2.5%,pH值为4.5~5的溶壁酶酶液,在酶液量与菌丝体的比值为20:1(V/W),温度30℃,转速为50r/min条件下酶解3h,可得到最高的原生质体得率。其原生质体数可达15.35×107个/ml。本研究为今后进行杏鲍菇原生质体的诱变及融合育种奠定基础。
The conditions of preparation of Pleurotus eryngii protoplast were studied in details and systematically for the first time. Results showed that: the highest production rate of protoplast could be obtained by using 0.6mol/L mannitol, 2.5% lywallzyme and digesting for 3 h at the condition of 30℃, and 50r/min, pH value 4.5-5. The protoplast number of Pleurotus eryngii came to 15.35 × 10^7/ml.
