Comparative 16S rRNA gene sequence analysis and major physiological differences indicate two distinct sublineages within the genus Azoarcus: the Azoarcus evansii lineage, comprising Azoarcusevansii (type strain KB740T=DSM 6898T=CIP 109473T=NBRC 107771T), Azoarcusbuckelii (type strain U120T=DSM 14744T=LMG 26916T), Azoarcusanaerobius (type strain LuFRes1T=DSM 12081T=LMG 30943T), Azoarcustolulyticus (type strain Tol-4T=ATCC 51758T=CIP 109470T), Azoarcustoluvorans (type strain Td21T=ATCC 700604T=DSM 15124T) and Azoarcustoluclasticus (type strain MF63T=ATCC 700605T), and the Azoarcus indigens lineage, comprising Azoarcusindigens (type strain VB32T=ATCC 51398T=LMG 9092T), Azoarcus communis (type strain SWub3T=ATCC 51397T=LMG 9095T) and Azoarcusolearius (type strain DQS-4T=BCRC 80407T=KCTC 23918T=LMG 26893T). Az. evansii lineage members have remarkable anaerobic degradation capacities encompassing a multitude of alkylbenzenes, aromatic compounds and monoterpenes, often involving novel biochemical reactions. In contrast, Az. indigens lineage members are diazotrophic endophytes lacking these catabolic capacities. It is proposed that species of the Az. evansii lineage should be classified in a novel genus, Aromatoleum gen. nov. Finally, based on the literature and new growth, DNA-DNA hybridization and proteomic data, the following five new species are proposed: Aromatoleum aromaticum sp. nov. (type strain EbN1T=DSM 19018T=LMG 30748T and strain pCyN1=DSM 19016=LMG 31004), Aromatoleum petrolei sp. nov. (type strain ToN1T=DSM 19019T=LMG 30746T), Aromatoleum bremense sp. nov. (type strain PbN1T=DSM 19017T=LMG 31005T), Aromatoleum toluolicum sp. nov. (type strain TT=DSM 19020T=LMG 30751T) and Aromatoleum diolicum sp. nov. (type strain 22LinT=DSM 15408T=LMG 30750T).
