Strain 101/1, isolated from petroleum wastewater sediment was classified as Pseudomonas aeruginosa. In wild type condition the strain tolerated phenol in concentration 1,000 mg/L under aerobic conditions and 800 mg/L under denitrifying conditions. As a result of adaptation to phenol the resistance of the strain to the compound increased to 1,600 and 1,400(More)
The growth and uptake of phenol by 8 strains isolated from wastewater sediments in stationary cultures in medium with increasing concentrations of phenol (from 100 to 600 mg/L) under denitrifying conditions were studied. All the strains grew in media containing 250 mg phenol/L and only strains 101/1, 83/2 and 21/1/ in consecutive passages visibly increased(More)
Detailed studies on the efficiency of phenol degradation by a biofilm in an anaerobic packed bed reactor were carried out. The efficiency of phenol degradation depended on both the concentration of phenol in the medium and the phenol load in anaerobic packed bed reactor. Increasing phenol concentrations from 200 to 1,250 mg l(-1) and retention time (Tr)= 12(More)
