Lignocellulose degradation by fungi was visualized on plates containing guaiacol, which indicates the activity of lignocellulolytic enzymes that catalyse the oxidative polymerization of guaiacol and result in reddish brown zones in the media45. Lignocellulose degradation ability by fungi is directly proportional to the size and depth of the reddish-brown zones. Furthermore, the larger and deeper the reddish-brown zones, the stronger the lignocellulose degrading ability.
