Sandia-led team demonstrates two efficient hybrid biochemical routes for lignin conversion to value-added chemicals

Green Car Congress

A Sandia National Laboratories-led team has demonstrated two new routes to lignin conversion that combine the advantages of earlier methods while minimizing their drawbacks. Conversely, harsh chemicals can deconstruct lignin in hours or even minutes. Instead, the team genetically engineered a tobacco plant. —Seema Singh.
