Doubling time (dt, in hours) of a culture of Staphylococcus haemoliticus strain 10SBZ1A in the presence of benzo(a)pyrene (BaP), along with various aromatic substrates.
All substrates were used at 40 μmole.l-1.

Values of degradation rates of benzo[a]pyrene (BaP) reported in various studies.
Studies A were cultures of single strains, in minimum mineral media (MM); studies B consisted of consortia of bacteria in MM or rich medium, or single bacterial strain but in rich media. References are listed in the text, in the Results/Discussions section.
