White-rot and brown-rot fungi: two routes to lignin and cellulose decay

3 steps

White-rot basidiomycetes secrete class II peroxidases (lignin, manganese, versatile) and laccases that oxidize lignin and leave a pale, cellulose-rich residue
Brown-rot fungi lack class II peroxidases and use Fenton chemistry (Fe2+ + H2O2 gives hydroxyl radicals) to depolymerize cellulose, leaving modified lignin
Lignin is co-metabolized: fungi need cellulose or another carbon source and H2O2 from oxidases; lignin alone does not support growth
