The present disclosure provides recombinant microorganisms and methods for the anaerobic production of 2,4-furandicarboxylic acid from one or more carbon sources. The microorganisms and methods provide redox-balanced and ATP positive pathways for co-producing 2,4-furandicarboxylic acid with ethanol and for co-producing 2,4-furandicarboxylic acid with ethanol and 1-propanol. The method provides recombinant microorganisms that express endogenous and/or exogenous nucleic acid molecules encoding polypeptides that catalyze the conversion of a carbon source into 2,4-furandicarboxylic acid and that coupled the 2,4-furandicarboxylic acid pathway with an additional metabolic pathway.

Disclosed herein include methods of reducing the viscosity of a starch slurry during starch processing by the addition of one or more surfactants and one or more amylases. In some embodiments, the unexpected reduction in slurry viscosity results in a surprising increase in corn oil recovery, reduction in residual starch, and increased fermentation rate.
