Alexander Paul Mueller, Michael Koepke, Shilpa Nagaraju: Recombinant microorganisms and uses therefor. LANZATECH NEW ZEALAND, Andrea Schoen, February 13, 2018: US09890384

Carboxydotrophic acetogenic microorganisms do not produce MEK and/or 2-butanol. They lack the biosynthesis pathways to make these products. In addition, they produce the intermediate (R,R)-2,3-butanediol whereas the production of MEK and 2-butanol requires production of the intermediate (R,S)-2,3-bu ...
