Abstract: 

Different samples from a reactor system for the cleaning of an emulsified waste oil containing approximately 1% of different polycyclic aromatic hydrocarbons (PAH) were studied for the diversity of phenanthrene, anthracene, and acenaphthene-metabolizing bacteria. From more than 28 different taxa found in the airlift-suspension reactor, nine were able to mineralize at least one of the PAH, belonging to the genera Bacillus, Mycobacterium, Nocardia, Sphingomonas, Alcaligenes, Pseudomonas, and the Flavobacterium/Cytophaga group. In the sludge from the thickener of the reactor system, a reduced number of metabolically active groups could be detected. The impact of different precultivation substrates on the degradation capability was investigated with five PAH-degrading bacterial strains. Four isolates were influenced by the precultivation substrates, however, one isolate (Alcaligenes-like) as well as the mixture of the five strains showed no changes in their degradation capability. The results indicated a strong impact of the precultivation methods on the composition of bacterial communities and the activity and the degradation characteristics of bacteria with respect to different PAH.
