The genus Terrabacter comprises several strains with the ability to oxidize complex aromatic compounds such as dibenzofuran, fluorene, dibenzo-p-dioxin, biphenyl, and 1,1-dichloro-2,2-bis(4-chlorophenyl)ethylene (DDE) (Aislabie et al. 1999; Monna et al. 1993; Iida et al. 2002a, Noumura et al. 2004; Zhou et al. 2006). Plasmid-borne genes were shown to be involved in the degradation of aromatic compounds by Terrabacter sp. strains YK3 and DBF63; however, the plasmid of strain YK3 is circular (Iida et al. 2002a), whereas strain DBF63 carries two linear plasmids (Nojiri et al. 2002).
