| 中文摘要: |
| 研究了菌龄、渗透压稳定剂、酶的种类及浓度、酶解时间和再生培养基等因素对淡紫拟青霉菌IPC菌株原生质体形成和再生的影响,结果表明,IPC菌株原生质体形成的最适宜条件为:菌龄20 h,用5 mg/mL蜗牛酶,0.8 mol/L NaCl的渗透压稳定剂,酶解2～3 h;原生质体涂布于含0.6 mol/L NaCl、0.5%琼脂的再生培养基上,再生率最高。 |
| 英文摘要: |
| The effects of such factors as mycelial age,osmotic stabilizers,enzymes and their concentration,lysis time and regeneration media on the formation and regeneration of the protoplasts of Paecilomyces lilacinus were studied.The optimum conditions are as follows: mycelia of 20h,5mg/mL snailase,0.8mol/L NaCl as osmotic stabilizer and lysis time of 2～3h.The regeneration percentage was the highest when the protoplasts were plastered on 0.5% agar media with(0.6 mol/L) NaCl. |
