Phenol-degrading denitrifying bacteria in wastewater sediments.
An attempt was made to isolate denitrifying bacteria capable of degrading phenol from anoxic wastewater sediments and compost (vegetable soil). The greatest phenol-degrading activity was shown by autochthonous microflora from petroleum wastewater sediments (PWS) and by denitrifying microflora from nitrogenous wastewater reservoir sediment (NWRS). Eight strains of denitrifying bacteria able to degrade phenolic compounds were isolated, six of which were from the petroleum wastewater sediments. The highest activity of phenol degradation (23.5 and 23 mg/L/day) in denitrifying conditions was shown by strains 54/1 and 83/2, both from petroleum wastewater sediments, which were classified as Pseudomonas aeruginosa and Alcaligenes faecalis, respectively.
