摘要
以2,2-连氮-双(3-乙基苯并噻唑-6-磺酸)(ABTS)为底物,研究了Cu2+离子对漆酶活性的影响。实验结果表明,漆酶的活性受pH的影响非常大;Cu2+离子在不同的pH范围和浓度下,对漆酶的活性有不同的作用。
By assaying the laccase activity wit h the substrate(ABTS)we find that the copper ion(Ⅱ)have different effect on laccase activity at different pH value and di fferent Cu 2+ concentration.When the pH value is u nder 4and the concentration is 1～10m g /L,the Cu(Ⅱ)inhabits the laccase.While the pH va lue is higher than 4.5at the concentr ation 1～10mg /L,the Cu(Ⅱ)can increase the activity of laccase.The Cu 2+ concentration 20mg /L is a turning point in all pH value.
