Oriol Gutierrez Wastewater transport along sewers favors the colonization of inner pipe surfaces by wastewater-derived microorganisms that grow forming biofilms. Science of the Total Environment. In this study, the concentration of antibiotics, integron intI1 and antibiotic resistance genes qnrS, sul1, sul2, blaTEM, blaKPC, ermB, tetM and tetW , and potential bacterial pathogens were analyzed in wastewater and biofilm samples collected at the inlet and outlet sections of a pressurized sewer pipe. Significant differences in the relative abundance of gene intI1 and genes conferring resistance to fluoroquinolones qnrS , sulfonamides sul1 and sul2 and betalactams blaTEM were only measured between inlet and outlet biofilm samples. Gases de efecto invernadero en los sistemas de transporte y tratamiento de aguas residuales: Applied and Environmental Microbiology. Sewer biofilms thus appear as an optimal habitat for the dispersal and accumulation of antibiotic resistance genes ARGs. Microbial activity and diversity in sewer biofilms: Iron salts dosage for sulfide control in sewers induces chemical phosphorus removal during wastewater treatment.

Changes in microbial biofilm communities during colonization of sewer systems. Leads the research line in sewer systems at the Catalan Institute for Water Research. Implications of Downstream Nitrate Dosage in anaerobic sewers to control sulfide and methane emissions. Water Science and Technology. Significant differences in the relative abundance of gene intI1 and genes conferring resistance to fluoroquinolones qnrS , sulfonamides sul1 and sul2 and betalactams blaTEM were only measured between inlet and outlet biofilm samples. Gases de efecto invernadero en los sistemas de transporte y tratamiento de aguas residuales: Laboratory assessment of bioproducts for sulfide and methane control in sewer systems. Our study highlights the role of sewer biofilms as source and sink of ARB and ARGs and supports the idea that community composition rather than antibiotic concentration is the main factor driving the diversity of the sewage resistome. A new method for testing effectiveness of sulfide-control chemicals used in sewer systems. Life cycle assessment of urban wastewater systems: Greenhouse gas emissions form Nitrification processes in Wastewater treatment plants. Assessment of pH shock as a method for controlling sulfide and methane formation in pressure main sewer systems. Quantifying the relative contribution of sewer systems Water Research 77, pp Effects of long-term pH elevation on the sulfate-reducing and methanogenic activities of anaerobic sewer biofilms. Iron salts dosage for sulfide control in sewers induces chemical phosphorus removal during wastewater treatment. These biofilms are composed of rich and diverse microbial communities that are continuously exposed to antibiotic residues and antibiotic resistant bacteria ARB from urban wastewater. The most abundant ARGs detected in both wastewater and biofilm samples were sul1 and sul2 with roughly 1 resistance gene for each 10 copies of 16s RNA gene.
