Degradation of phenanthrene, methylphenanthrenes and dibenzothiophene by a Sphingomonas strain 2mpII

Nadalig T, Raymond N, Gilewicz NM, Budzinski H, Bertrand JC

Strain Sphingomonas sp. (2MPII), isolated from marine sediment, was able to utilize phenanthrene (P) or 2-methylphenanthrene (2MP) as the sole carbon source. However, 9-methylphenanthrene (9MP) and dibenzothiophene (DBT) were weakly degraded. The degradation rates of 9MP and DBT increased in the presence of 2MP, whilst the degradation rate of 2MP increased in the presence of 9MP. However, the presence of DBT inhibited the degradation of 2MP. DBT sulfone, a DBT metabolite, was not assimilated by the bacteria and its presence also decreased the degradation rate of 2MP.
