Biomimetic metalloporphines and metalloporphyrins as potential tools for delignification: Molecular mechanisms and application perspectives

•Lignin is a structurally complex and chemically resistant plant macromolecule.•Chemical delignification implies harsh conditions and high environmental impact.•White-rot fungi have enzymatic machineries allowing oxidative delignification.•Selected metalloporphines act as peroxidase/peroxygenase-like systems in ligninolysis.•Biomimetic metalloporphines show drawbacks and advantages in comparison to enzymes.
