Obligate anaerobic acetic acid producing microorganism and recombinant microorganism

摘要

A modified obligate anaerobic acetic acid-producing microorganism in which the activity of at least one enzyme selected from the group consisting of a restriction enzyme, a modification enzyme, and a recognition enzyme constituting a type I restriction modification enzyme is deleted or suppressed Is provided. It is preferable that at least the activity of the restriction enzyme is deleted or suppressed. The obligately anaerobic acetic acid-producing microorganism is preferably a Clostridium bacterium or a Moorella genus bacterium, particularly preferably Clostridium ljungdahlii.
