Leveraging the Power of Ligninolytic Enzymes to Valorize Lignin to Polyvinyl Phenol
Lignocellulosic biomass is a renewable carbon-rich resource from plants and has attracted focus as an alternative source to fossil fuels. This study valorized p-coumaric acid, a major constituent component in lignin, using engineered bacterium to convert into the substituted phenol, 4-vinylphenol. Then, using ligninolytic enzymes, 4-vinylphenol was polymerized into polyvinyl phenol, a biopolymer. 13C pathway analysis was conducted to determine metabolic utilization of the p-coumaric acid, and in situ experiments were conducted to polymerize the monomer phenols. The resulting polymer was characterized using NMR and SEC (GPC) analysis.
