Anaerobic degradation of anionic surfactants by indigenous microorganisms from sediments of a tropical polluted river in Brazil

The aim of this study was to evaluate the ability of the microorganisms present in the sediment of the Tietê river to degrade anionic surfactant – linear alkylbenzene sulphonate (LAS)  in the reactor operated in batch sequences under denitrifying conditions.  The reactor was fed with synthetic subst...
