Title: Biocatalysts and methods for conversion of hemicellulose hydrolysates to biobased products

The invention relates to processes and biocatalysts for producing ethanol and other useful products from biomass and/or other materials. Initial processing of lignocellulosic biomass frequently yields methylglucuronoxylose (MeGAX) and related products which are resistant to further processing by common biocatalysts. Strains of Enterobacter asburiae are shown to be useful in bioprocessing of MeGAX and other materials into useful bioproducts such as ethanol, acetate, lactate, and many others. Genetic engineering may be used to enhance production of desired bioproducts.
