The COVID-19 pandemic influenced the temporal dynamics of antimicrobial resistance markers and bacterial community across urban wastewater treatment plants

Urban wastewater systems represent important interfaces between human activity and the environmental occurrence of antimicrobial resistance (AMR) markers. We assessed the temporal dynamics of intI1, ermB, and the 16 S rRNA gene by quantitative PCR across three wastewater systems (EPC, CJC, and JW) in Fortaleza, Brazil,...

Can microaeration and hydraulic retention time steer anaerobic microbiomes toward efficient linear alkylbenzene sulfonate degradation?

The sustainable treatment of surfactant-rich wastewater in anaerobic systems is often hindered by the biochemical recalcitrance of linear alkylbenzene sulfonate (LAS) and its inhibitory effects on methanogenesis. This study investigated controlled microaeration under two hydraulic retention time (HRT) and organic loadi...

Microbial Dynamics during the Removal of Linear Alkylbenzenesulfonate (LAS) under Anaerobic and Microaerobic Conditions with Different Co-substrates

Linear alkylbenzenesulfonate (LAS) is the most widely used anionic surfactant and is commonly found in wastewater due to its extensive use in detergents and cleaning products. Although LAS is biodegradable, its degradation in anaerobic environments remains a challenge, often requiring the addition of co-substrates and...
