"Aromatoleum" is a genus of bacteria capable of microbial biodegradation of organic pollutants.

However, the strain EbN1 has not been described in detail, therefore, according to the International Code of Nomenclature of Bacteria,[1] the name "Aromatoleum aromaticum" is not valid[2] and should be officially referred to as Azoarcus sp.

[3] The discovery of the strain was published in 1995,[4] and was subsequently referred to in the literature as "Aromatoleum aromaticum" and cited as "(Rabus, unpublished data)".

It has one chromosome and two plasmids, encoding for 10 anaerobic and 4 aerobic aromatic degradation pathways.

Unlike many species in Azoarcus proper, it is incapable of fixing nitrogen.
