摘要
测定了6种常见金属离子对香菇(Lentinula edodes)羧甲基纤维素酶、漆酶和木质素过氧化物酶活性的影响。结果表明,Na^+、K^+、Ca^(2+)、Mn^(2+)、Fe^(2+)、Mg^(2+)对香菇羧甲基纤维素酶活性具有激活作用,其中K^+激活效果最强;Fe^(2+)能明显抑制漆酶活性;Mn^(2+)、Ca^(2+)、K^+、Mg^(2+)和Fe^(2+)对木质素过氧化物酶活性有抑制作用,Na^+对木质素过氧化物酶活性具有激活作用。
The effects of six kinds of metal ions on the activities of carboxymethyl cellulase, laccase and lignin peroxidase were analyzed in the paper. The results showed that Na^+, K^+, Ca^2+, Mn^2+, Fe^2+ and Mg^2+ could improve carboxymethyl cellulase activity, and among them K^+ had the strongest activation effect, Fe^2+ could decrease laccase activity, Mn^2+, Ca^2+, K^+, Mg^2+ and Fe^2+ could decrease lignin peroxidase activity, while Na^+ could improve lignin peroxidase activity.
