Dégradation d'un tensio-actif commercial, en présence d'une source complémentaire de carbone, par une communauté bactérienne sélectionnée en milieu marin

Abstract

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.[Traduit par la revue]
