METHODS, SYSTEMS AND COMPOSITIONS FOR INCREASED MICROORGANISM TOLERANCE TO AND PRODUCTION OF 3-HYDROXYPROPIONIC ACID (3-HP)

摘要

The present invention relates to methods, systems and compositions, including genetically modified microorganisms, adapted to exhibit increased tolerance to 3-hydroxypropionic acid (3-HP), particularly through alterations to interrelated metabolic pathways identified herein as the 3-HP toleragenic pathway complex ("3HPTGC"). In various embodiments these organisms are genetically modified so that an increased 3-HP tolerance is achieved. Also, genetic modifications may be made toprovide at least one genetic modification to any of one or more 3-HP biosynthesis pathways in microorganisms comprising one or more genetic modifications of the 3HPTGC.
