Effect of pH on the stability of T. harzianum S7113 purified laccase isoenzymes a Lac A, and b Lac B. The pH stability of the enzyme was investigated by incubating the enzyme solution in 0.1 M citrate and Tris buffers (pH 3, 5, 7, and 9) at 40 °C for 2 h. The residual activity was estimated after incubation using ABTS as the substrate
