Developments in lignin degradation: New microorganisms and enzymes at play

Lignin, a chief component of cell walls in plants, is naturally degraded in the soil. Identifying new microorganisms involved in this degradation can help develop novel lignin breakdown processes in industrial settings. Now, researchers have isolated 8 microorganisms that degrade the lignin model compound 2-phenoxyacetophenone (2-PAP). They found that one of these microbes uses a new, unidentified enzyme to cleave the ether-bonds in 2-PAP, resulting in the formation of phenol and benzoate.
