用聚丙烯酰胺凝胶平板电泳法测定双孢蘑菇菌丝体的酯酶同工酶谱,表明同一菌株用马铃薯、葡萄糖、麦芽汁液体培养基(PDM)静止培养(24±1℃)45天的菌丝体酯酶同工酶与用该培养基摇床培养(23℃,71转/分)20天的菌丝体酯酶同工酶相同;酯酶提取液存放(4℃)的时间对酯酶同工酶谱的表现有很大的影响,即酯酶同工酶谱随酯酶提取液存放时间的延长而逐渐变糊乃至消失;双孢蘑菇种内菌株间的酯酶同工酶差异显著。与测定双孢蘑菇子实体组织的酯酶同工酶的方法相比较,测定双孢蘑菇菌丝体酯酶同工酶的方法具有简便、可靠、灵敏等优点,因而它为双孢蘑菇菌株的早期鉴定提供了一种有用的手段。
The esterase isozyme pattern of Agaricus bisporus mycelia was determined by polyacrylamide gel electrophoresis, indicating that the same strain was still cultured (24 ± 1 ° C) for 45 days in potato, glucose, and malt broth (PDM) Mycelia esterase isoenzymes were the same as mycelial esterase isoenzymes cultured in this medium for 20 days at 23 ℃ (71 rpm); the time of esterase extract storage (4 ℃) Esterase isozyme profile of the performance has a significant impact, that is, esterase isozyme profile with esterase extract storage time gradually become fuzzy or even disappear; Agaricus bisporus isolates Esterase between workers Enzymes significantly different. Compared with the method of determining the esterase isozyme in the fruiting bodies of Agaricus bisporus, the method for determining the esterase isozyme of the Agaricus bisporus mycelia has the advantages of simplicity, reliability, sensitivity, etc. Therefore, Early identification provides a useful tool.
