Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
I claim: 1. An isolated E. asburiae strain comprising the following genetic modifications: incorporation and expression of a gene encoding alcohol dehydrogenase, incorporation of a gene encoding pyruvate decarboxylase and inactivation of pyruvate formate lyase in said strain. 2. The isolated E. asburiae strain of claim 1 , wherein said strain comprises incorporation and overexpression of a Zymomonas mobilis gene encoding alcohol dehydrogenase, incorporati…
