Acetogens
Acetogens are the bacteria which have the following characteristics:
-
use the Wood-Ljungdahl pathway (WLP) for energy conservation
-
generate acetyl-Coenzyme A (CoA) by reduction of two molecules of carbon dioxide
-
may or may not produce acetate as the main end product of carbon fixation by WLP
-
are obligate anaerobes, with some members having tolerance to periods of aerobiosis
