[1] The name, Acetobacterium, has originated because they are acetogens, predominantly making acetic acid as a byproduct of anaerobic metabolism.
Most of the species reported in this genus are homoacetogens, i.e. solely producing acetic acid as their metabolic byproduct.
The step in the electron transport chain that creates the sodium gradient is the ferredoxin-dependent reduction of NAD+.
[4] One application of Acetobacterium, is that A. woodii could be used in the transformation of tetrachloromethane to dichloromethane and carbon dioxide by reductive dechlorinations, but the reactions taken to get to the final product are unknown.
Another application of A.woodii is that it can reduce the effects of greenhouse gases since A.woodii can be used to convert CO2 and CO into acetyl-CoA which could then be used to make other chemicals like ethanol and acetate.
