Some new aspects enzymatic lignin biodegradation

ABSTRACT

The present review focuses on some aspects of enzymology and on the ligninase mechanism in particular, with a survey of genetic studies carried out during the last few years. Some white-rot fungi are currently known to the most efficient lignin degrading organisms. Among them, Chrysonilia sitophila is emphasized for its high ligninolytic activity. Ligninases are enzymes which need H2O2 for activity and have intrinsic peroxidase activity. A free radical mechanism for ligninase-catalyzed degradation in suggested
