WN@TL: “Lignins: Intrigue and Controversies Surrounding a Little-Known Major Polymer”

Lignin, comprising some 15-30% of plant biomass, is arguably the 2nd most abundant terrestrial biopolymer, yet many have never heard of it (although the term ‘lignocellulosics’ is now becoming more widespread). Its structure and biosynthesis are intriguing on many levels, and the theory of lignification has been delightfully controversial. We’ll attempt to highlight some of the intrigue with an emphasis on new findings that offer enhanced opportunities for ‘exploiting’ Nature’s most abundant source of aromatics.
