4 10 the laccase has a broad stable pH range. After 72 h incubation at 30°C, the enzyme shows a different stability pattern: the laccase activity decreases rapidly at pH 2.0, 43% remaining activity at pH 4.0 and pH 8.0, over 70% remaining activity at pH 10.0 with a half-life of more than 130 h, the laccase is more stable in an alkaline condition Pycnoporus sp.
