The biodegradation of lignin by the laccase enzyme system is an oxidative process consisting of enzyme-catalyzed and mediator-facilitated radical reactions. This process degrades both phenolic and non-phenolic aromatic structures in lignin.
Oct 1, 2020 (page 1) scientists from ga tech have studied a solution-based, dual-catalyst system for combined hydrogenation and deoxygenation of lignin.
Phanerochaete chrysosporium (atcc 20696) has a catabolic ability to degrade lignin. Here, we report whole-genome sequencing used to identify genes related to lignin modification. We determined the 39-mb draft genome sequence of this fungus, comprising 13,560 predicted gene models. Gene annotation provided crucial information about the location and function of protein-encoding genes.

The chemical, enzymatic, and molecular aspects of the fungal attack of lignin, which represents the key step in wood decay, are also discussed.
Lignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants. Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily.

Lignin is both the most abundant aromatic (phenolic) polymer and the second most abundant raw material. It is degraded and modified by bacteria in the natural world, and bacteria seem to play a leading role in decomposing lignin in aquatic ecosystems.
In the process, groups collect evidence to test predictions about which environmental microbial samples will be the most effective for degrading cellulose.
Despite numerous studies, it is not entirely clear which microbes, other than certain fungi, degrade the lignin polymer. The uncertainty reflects the ex- perimental difficulties mentioned above and insufficient comprehensive study with selected species.
This book records the proceedings of an international seminar on lignin biodegradation held may 9 to 11, 1978 and provides a state-of-the-art summary of research. It reviews the lignin structure, morphological distribution in plant cell walls and the microbial catabolism of relevant aromatics.

For acidic biodegradation, lignin was chemically pretreated with hydrogen peroxide. Alkaline biodegradation was achieved by developing the bacterial growth on luria and bertani medium with alkali lignin as the sole carbon source. Coli bl21 (lacc) was used to carry out lignin biodegradation over 10 days of incubation.
