Abstract
The research was focused on the slurry-phase biodegradation of naphthalene in
soil. Among ex-situ techniques, the slurry-phase technique offers the advantage
to increase the availability of contaminants to bacteria. From soil samples
collected on a contaminated site, the Pseudomonas putida M8 strain capable to
degrade naphthalene was selected. Experiments were performed in a stirred and
oxygenated reactor. In this study the influence of air flow rate on volatilisation
and biodegradation of naphthalene was investigated. The hydrocarbon
disappearance, the carbon dioxide production, and the ratio of total heterotrophic
and naphthalene-degrading bacteria were monitored. The results obtained
confirm that the selected bioremediation technol
