Claim: Lignin peroxidase produced by some fungi like Phanerochaete chrysosporium degrades Lignin, cross-linked phenolic polymers, which is otherwise highly resistant to biodegradation.
Evidence: Lignin is highly resistant to biodegradation and only higher fungi and some bacteria are capable of degrading the polymer via an oxidative process. Lignin is found to be degraded by enzyme lignin peroxidases produced by some fungi like Phanerochaete chrysosporium. Well-studied ligninolytic enzymes are found in Phanerochaete chrysosporium and other white rot fungi.
