Important Issues and Results from Knut Lundquist's Lignin Research at Chalmers

This is a manuscript originally written by Knut Lundquist and Jim Parkås in a more popular science spirit on topics in lignin chemistry where Knut and Chalmers has contributed and Knut's view on the bearing of this research on lignin chemistry. The manuscript was never published and was translated from Swedish by Ulla Westermark and Jim Parkås with a new title. The following topics are briefly addressed: stereochemistry and its implication on lignin structure and lignin biosynthesis, lignin-carbohydrate bonds, oxidative lignin degrading enzymes, reactions of β-ethers at neutral and acidic conditions.
