Abstract:
Lignin is one of the most abundant renewable resources and is a common by-product of paper industry. Lignin with its complex aromatic polymer structure, forms an interesting raw material for obtaining chemicals like catechol, benzene and phenolic compounds. The mildest possible processing of lignin are enzymes like peroxidases and laccases which were used to specifically extract aromatic monomers such as catechol and vanillin. Two different lignins were analyzed, one lignin from Miscanthus and one of wheat straw. The conversion of lignins with enzymes showed that wheat straw lignin, with its lower molecular fraction is more suitable than the lignin from Miscanthus. Enzymic treatment without further energy consumption, result in up to 11 wt.% catechol and up to 15 wt.% monomers in total.
