In the UK, researchers from the Department of Chemistry at York have discovered a family of enzymes that can degrade hard-to-digest biomass into its constituent sugars. Reported in Nature Chemical Biology, the new research was led by Professor Paul Walton and Professor Gideon Davies at York and also involved Professor Bernie Henrissat, of CNRS, Aix-Marseille Université, Marseille, France. It opens up major new possibilities in the production of bioethanol from sustainable sources. By studying the biological origins and the detailed chemistry of the enzyme family, the researchers have shown that Nature has a wide range of methods of degrading biomass which humankind can now harness in its own endeavor to produce sustainable biofuels.
