Due to the fact that aromatic compounds are characterized by a higher thermodynamic
stability than aliphatics, their decomposition process is more complex. The main role in this
process is played by oxygenase enzymes that are able to cleave the aromatic ring of the com-
pound. Aerobic degradation of hydrophobic pollutants such as benzene, toluene, naphtha-
lene, biphenyl or polycyclic aromatics is usually initiated by activation of the aromatic ring
through oxygenation, catalysed by members of the soluble di-iron family of monooxygenases
(Leahy et al. 2003) or Rieske non-haem iron oxygenases (Gibson & Parales, 2000). The pos-
sibility of bacteria to degrade many aromatic hydrocarbons is based on the existence inside
the cell of catabolic plasmids (e.g. TOL plasmid) that encode specific enzymes. The many of
aromatics can be converted to intermediates, such as catechol, 3-methyl catechol or prote-
catechuate (Fritsche & Hofrichter, 2008, Gülensoy & Alvarez, 1999).
