White-Rot Fungal Peroxidases Biotechnological Interest

Compared with plant and other peroxidases, white-rot fungal peroxidases are characterized by their high redox potential, related to the architecture of the heme environment (see Chap. 4). This is required to perform their role in nature, namely the oxidative biodegradation of the recalcitrant lignin polymer present in the cell wall of all vascular plants [30-32], By contrast, one of the roles of plant peroxidases 

An additional characteristic of white-rot fungal peroxidases is their wide-substrate specificity allowing them to oxidize substrates that shares structural characteristics with lignin units [38]. Among others, these enzymes are able to oxidize phenolic and nonphenolic pollutants [39], pesticides [40], polycyclic aromatic hydrocarbons [41] and industrial dyes [42]. These properties expand the range of applications also to the environmental sector.
