A megatransposon drives the adaptation of Thermoanaerobacter kivui to carbon monoxide - Nature Communications
Carbon monoxide (CO) present in syngas severely inhibits growth of many acetogens. Here, the authors adapt, characterize, and engineer utilization of CO as sole carbon and energy source by the thermophilic acetogen Thermoanaerobacter kivui.

One such class of secondary metabolizer is the acetogen. In the rumen, acetogens reduce carbon dioxide or organic acids to acetate. This happens via some variation on the Wood-Ljungdahl pathway, or the reductive acetyl-CoA pathway.
