• Strains identified as B1 has undergone specific tests, showing very satisfactory results. This suggests its adoption for the inoculum during the start-up of an attached-mass wastewater treatment plant.

Further studies are recommended to complete the analysis to fully understand the effect of xenobiotic substances on the strain growth, which have been shown to be expectedly well biodegraded, the biofilm formation and stability and the qualitative aspects of the effluent.

The present study offers a good and comprehensive basis for further research phases.
