One-Pot Enzymatic Production of Lignin-Composites.

A novel and efficient one-pot system for green production of artificial lignin bio-composites has been developed. Monolignols such as sinapyl (SA) and coniferyl (CA) alcohols were linked together with caffeic acid (CafAc) affording a polymeric network similar with natural lignin. The interaction of the dissolved SA/CA with CafAc already bound on a solid support (S/S-CafAc) allowed the attachment of the polymeric product direct on the support surface (S/S-CafAc-L and S/S-CafAc-L, from CA and SA, respectively).
