Six bacterial strains capable of utilizing phenol as a sole carbon source were isolated from the activated sludge of a wastewater treatment plant. On the basis of some cytological and biochemical characteristics and fatty acid profiles, the strains AEK1, AEK2, AEK5, AEK6, AEK8 and AEK11 could be identified as Pseudomonas syringae, Actinomadura yumaensis, Pseudomonas radiora, Pesudomonas putida, Pseudomonas mendocina and Bacillus dipsosauri, respectively. Actinomadura yumaensis and Bacillus dipsosauri were not known previously as being capable of phenol degradation. Crude extracts of pseudomonads showed the higher phenol degradation performance. As a result of enzyme screening, it was found that P. radiora has a meta pathway while the other three Pseudomonas species have ortho pathways.
