AB  - Parabens have been detected in drinking water (DW) worldwide, however, their 
      impact on DW microbial communities remains to be explored. Microorganisms can 
      easily adapt to environmental changes. Therefore, their exposure to contaminants 
      of emerging concern, particularly parabens, in DW distribution systems (DWDS) may 
      affect the microbiological quality and safety of the DW reaching the consumers 
      tap. This work provides a pioneer evaluation of the effects of methylparaben 
      (MP), propylparaben (PP), butylparaben (BP), and their combination (MIX), in 
      bacterial biofilms formed on different surfaces, representative of DWDS materials 
      - high-density polyethylene (HDPE), polypropylene (PPL) and polyvinyl chloride 
      (PVC). Acinetobacter calcoaceticus and Stenotrophomonas maltophilia, isolated 
      from DW, were used to form single and dual-species biofilms on the surface 
      materials selected. The exposure to MP for 7 days caused the most significant 
      effects on biofilms, by increasing their cellular culturability, density, and 
      thickness up to 233%, 150%, and 224%, respectively, in comparison to non-exposed 
      biofilms. Overall, more pronounced alterations were detected for single biofilms 
      than for dual-species biofilms when HDPE and PPL, demonstrating that the surface 
      material used affected the action of parabens on biofilms. Swimming motility and 
      the production of virulence factors (protease and gelatinase) by S. maltophilia 
      were increased up to 141%, 41%, and 73%, respectively, when exposed to MP for 7 
      days. The overall results highlight the potential of parabens to interfere with 
      DW bacteria in planktonic state and biofilms, and compromise the DW 
      microbiological quality and safety.
