The percentages of bacteria degrading fuel oil (n-paraffins from C12 to C28) were determined in three stations in the northern part of Venice Lagoon. Concentrations of paraffin-degrading bacteria ranged from 8 to 70 bacteria per 100 mL in the least polluted station close to the sea, and from 33 to 345 bacteria per 100 mL in the most polluted station near Porto Marghera. Biological oxygen demand with fuel oil additions was higher in this station, where oxygen was totally depleted in 7 and 5 days in November and June respectively. Twenty-five bacterial strains were isolated from agar plates amended with fuel oil as the sole carbon and energy source; only two were Acinetobacter spp. strains. Strain VE-C3 grew in the presence of n-paraffins. Growth was inducible with a generation time of 2.77 h and an oxygen consumption rate of 53 μL h-1 mg-1 of cells (d.w.). Five other strains thrived on intermediate oxidation products of n-paraffin.
