Acetogenic Organisms

(First aired 14th April 2021)

This webinar explores the biochemistry, physiology, genetics, and metabolic engineering of acetogenic organisms which make extensive use of single carbon C1 molecular pathways in their growth and metabolism. Acetogens use the Wood-Ljungdahl pathway to grow on single carbon C1-gases (CO2 and CO) as their sole carbon source, a pathway to reduce CO2 to acetate via a series of C1-intermediates bound to tetrahydrofolic acid. They may be used in the production of valuable products such as acetate or ethanol from abundant greenhouse gases.

This webinar will go into detail on two reviews that focus on the challenges of genetically and metabolically modifying acetogens, and describing the biochemistry and bioenergetics of methanol conversion in the biotechnologically interesting group of anaerobic, acetogenic bacteria.
