LITERATURE
2 - 5
the enzyme retains over 60-70% of the peak activity at pH 3.0 and 5.0 for both Malchite Green and Methyl Violet. The enzyme retains more than 60% of its activity at pH 2.0 and 4.0 for Reactive Black 5
3 - 4
3 - 4.5
-
the oxidation of 2,6-dimethoxyphenol occurs with with approximately 95% and 90% of the maximum activity at pH 3.0 and 4.0, respectively. Above pH 4.0, 2,6-dimethoxyphenol oxidation drops rapidly to 20% at pH 5.0 and to almost zero at pH 6.0. On the other hand, over 40% activity remains at pH 2.0. The oxidation of Reactive Blue 5 occurs with with approximately 50% of the maximum activity at pH 3.0 and 4.5, respectively
3 - 5
more than 50% of activity is conserved between pH 3.0 and 5.0. At lower or higher pH values, less than 25% of activity remains
4 - 5.5
-
the curve for the oxidation of Mn2+ shows appreciable activities down to pH 4.0 and up to pH 5.5 (80-90% in relation to the maximal activity). Mn2+ oxidizing activities are still detectable at less optimal pH above 5.5
4 - 9
the enzyme shows more than 35% activity at pH 4.0-9.0
5.5 - 8
-
free enzyme shows 25% of initial activity within a pH range between 6.0 and 8.0. The immobilized enzyme displays better activity in a broader pH range than the free peroxidase, which reaches around 58, 72, 82, 88, and 71% at pH 5.5, 6.0, 6.5, 7.5, and 8.0, respectively
