Heterocyclic aromatic compounds are part of many natural products and of chemical building blocks of e.g. herbicides. N-heterocyclic compounds, e.g. pyridine, picoline or quinoline or S-heterocyclics such as thiophene and benzothiophene can be found in coke effluents. O-heterocyclis are formed by the Maillard reaction. In contrast to carbon cyclic compounds the information regarding the bacterial degradation of heterocyclic compounds is rare (Berry et al 1987; Ensley 1984; Shukla 1984; Trudgill 1984). The formation of intensely coloured compounds is due to chemical side reactions, whose degradation might constitute a real problem. In most cases the substances are toxic already at low concentrations. Halogenated compounds are even more toxic (Naik et al 1972). Their decomposition often requires an initial photolytic destruction.
