摘要
为了研究杏鲍菇菌丝体胞内和胞外SOD的提取条件与活力变化,我们对菌丝体振荡提取时间和胞内酶提取SOD条件,不同生长阶段菌丝体SOD活力进行研究,结果表明,振荡法提取30min可以达到好的提取效果,杏鲍菇菌丝体在刚出菇时总SOD、胞内酶、胞外酶SOD活力都达到最高,随着杏鲍菇的生长,其菌丝体SOD的胞内酶百分比逐步降低,而胞外酶的百分比逐步增高。
In order to study the extraction conditions and vitality of SOD in pleurotus eryngii mycelia,we studied the vibration extraction time of mycelium and SOD extraction conditions by intracellular enzymes,and the SOD activity of mycelia at different growth stages.The results showed that vibration extraction for 30 minutes can achieve a good extraction effect.The total SOD,intracellular enzyme and extracellular enzyme SOD activity of pleurotus eryngii mycelium are the highest when they just emerged.With the growth of pleurotus eryngii,the percentage of intracellular enzymes in SOD of its mycelium gradually decreased,while the percentage of extracellular enzymes gradually increased.
