[Degradation of a commercial surface-active agent, in the presence of a complementary source of carbon, by a selected bacterial colony in a marine environment].
Bacterial communities that can degrade surfactants have been selected from coastal seawaters contaminated by urban sewages. Only the linear fraction of commercial anionic surfactants was quickly degraded, and a residual fraction representing 10% of the initial concentration always remained. The highest concentrations of surfactant tolerated by these communities depend on the nature of the co-substrate and on the degree of adaptation of the selected bacteria.
