Lignin Depolymerization

To some, lignin appears to be a foreign substance resembling a randomly modified polystyrene polymer, not resembling any of the more familiar biopolymers composed of carbohydrates, amino acids or nucleotides. However, next to cellulose, it is the second most abundant biopolymer on earth comprising as much as 30% of the dry mass of wood. Unlike other biopolymers, enzymatic degradation is oxidative versus hydrolytic and is limited to a select group of fungi and bacteria. Lignins appear to be heterogeneous and random with regards to degree of polymerization, branching, and monomer composition and sequence.
