Abstract

Official abstract text for this publication.

Methods for the fermentive production of four carbon alcohols are provided. Specifically, butanol, preferably 2-butanol is produced by the fermentive growth of a recombinant bacteria expressing a 2-butanol biosynthetic pathway. The recombinant microorganisms and methods of the invention can also be adapted to produce 2-butanone, an intermediate in the 2-butanol biosynthetic pathways disclosed herein.

First claim

Opening claim text (preview).

What is claimed is: 1. A recombinant microbial host cell comprising heterologous DNA molecules encoding polypeptides that catalyze the substrate to product conversions below: i) pyruvate to alpha acetolactate; ii) alpha acetolactate to acetoin; iii) acetoin to 2,3-butanediol; and iv) 2,3-butanediol to 2-butanone; wherein said microbial host cell produces 2-butanol; and wherein the polypeptide that catalyzes the substrate to product conversion of 2,3-butanediol to 2-butan…
