摘要: 以褐环乳牛肝菌为试验材料,从酶学的角度,通过测定超氧化物歧化酶(SOD)与酸性磷酸酶(ACP)活性、脯氨酸(Pro)与丙二醛(MDA)含量以及相对电导率的变化,研究了菌丝体培养过程中菌丝体活力与这几项测试指标的相关性,为对供试菌株在液体培养条件下的菌丝体活力进行评价探索可行方法。结果表明,菌丝体的酸性磷酸酶活性与菌丝体生物量变化趋势有较好的一致性;菌丝体相对电导率在菌丝体生长最旺盛时,其值最低。这两项指标可作为反映菌丝体活力的指标。超氧化物歧化酶活性、脯氨酸与丙二醛含量也可作为反映菌丝体活力的参考指标。

关键词: 褐环乳牛肝菌, 菌丝体活力, 电导率, 酸性磷酸酶

Abstract: The relativity between mycelial activity and several indexes were studied by determining the activity of SOD and ACP, the content of Pro and MDA and relative conductance of Suillus luteus (L.: Fr.) Gray mycelia. The results showed that the mycelial ACP activity was consistent preferably with the change of mycelial biomass. The mycelial relative conductance was the lowest when the mycelia grew fastest. These two indexes could be regarded as mycelial activity indexes. SOD activity and the content of Pro and MDA could also be regarded as referenced indexes of mycelial activity.

Key words: Suillus luteus, Mycelial activity, Relative conductance, ACP
