Phenol degradation efficiency of Pseudomonas putida PCM2153 free cells was experimentally studied. Bacterial cells were acclimatized to phenol what relied on gradually increasing the phenol concentration in the medium. The highest phenol degradation rate was calculated as approximately 15.2 mgźdm-3źh-1. Investigated strain degraded the phenol at the concentration of 400 mgźdm-3 in 24 h. The result of toxicity analysis showed that acclimatized cells of P. putida PCM2153 are able to survive even at as high concentration of phenol as 3000 mgźdm-3. The obtained result suggests that the analyzed strain can be used for effective treating of high strength phenolic wastewater. Due to resistance of the strain to high phenol concentration it may be applied in bioremediation of exceedingly contaminated sites, especially where dilution of pollutants cannot be implemented.

W doświadczeniu analizowano efektywność rozkładu fenolu przez szczep Pseudomonas putida PCM2135. Komórki bakteryjne zostały poddane adaptacji do wysokich stężeń fenolu, która polegała na stopniowym zwiększaniu jego stężenia w pożywce. Maksymalna szybkość rozkładu fenolu wyniosła 15,2 mgźdm-3źh-1. Badany szczep usunął 400 mg fenolu w ciągu 24 godzin. Przeprowadzone testy toksyczności wykazały, że zaadaptowane komórki P. putida PCM2153 są zdolne do przeżycia w roztworze fenolu nawet o stężeniu 3000 mgźdm-3. Uzyskane wyniki sugerują, że badany szczep może być wykorzystany do efektywnego oczyszczania ścieków charakteryzujących się wysokim stężeniem fenolu. W zawiązku z odpornością szczepu na wysokie stężenia fenolu, może on być wykorzystywany do bioremediacji terenów silnie zanieczyszczonych fenolem, gdzie rozcieńczanie zanieczyszczeń jest niemożliwe.
