Abstract

Compositions and methods are provided for enhancing saccharification of biomass derived from a genetically modified plant with one or more enzymes to enhance availability of substrates for fermentation by a microorganism. Microorganisms are also modified to enhance activity of one or more hydrolytic enzymes that are present endogenously in or are introduced heterologously into a host microorganism.
