Detailed explanation-1: -White rot fungi (WRF) are able to degrade lignin most effectively due to the production of ligninolytic extracellular oxidative enzymes; they belong to Basidiomycota . They decompose wood, leaving wood residues that are usually whitish in color and fibrous in texture.
Detailed explanation-2: -White-rot fungi are among the microorganisms in nature that can mineralize lignin into carbon dioxide and water. Lignin is degraded by their unique H2O2 production and extracellular enzyme system.
Detailed explanation-3: -White-rot fungi are more commonly found on angiosperm than on gymnosperm tree species in nature, and they may cause non-selective or simultaneous rot, whereas some white-rot fungi degrade lignin in woody plant cell walls to a higher extent than cellulose, and they are called selective white-rot fungi. 15.
