Title: Biomass conversion to fuels and chemicals

Abstract

This disclosure relates to compositions and methods for converting biomass to various chemical intermediates and final products including fuels. Aspects include the depolymerization of lignin, cellulose, and hemicellulose to a wide slate of depolymerization compounds that can be subsequently metabolized by genetically modified bacterium, and converted to cis,cis-muconic acid. Other aspects include the use of monometallic catalysts for converting the cis,cis-muconic acid to commodity chemicals and fuels, for example adipic acid and/or nylon.
