You can now watch the Wetsus webinar AMR in wastewater, determinants and removal online here. Prof David W Graham is one of three invited speakers in the webinar, along with Rebeca Pallares Vega and Dr Maarten Nederlof.
We are happy to present our new publication in Environmental Science & Technology. This paper is from Mui-Choo (Florence) Jong’s PhD research on antibiotic resistance (AR) gene transfer in low-energy sponge bioreactors. Florence showed sequential redox conditions generally enhanced AR gene removal, but she also observed very different gene transfer frequencies under different conditions. To test this observation, she developed a reporter assay using a green-fluorescent-protein tagged E. coli to track conjugative AR plasmid fate; the survival of the E. coli host cells; and gene exchange activity in aerobic, anoxic and anaerobic bioreactors, both in biofilms and the liquid phase. Overall, her work, reported in ES&T, show that aerobic conditions are better at reducing AR levels and gene transfer in wastewater ecosystems, perhaps due to the reduced host survival and in situ predation. This has major practical implications to wastewater treatment process design.

Also, David is chairing the session Water and wastewater: fate and treatment of AMR – Friday 30 October 12:00 – 14:00 CET, while Marcos is chairing the session Environmental exposures: Water and wastewater – Monday 2 November 20:00 – 22:00 CET.
It is official, Pani was been awarded her doctorate in Environmental Engineering. Her dissertation title is Assessing treatment technologies for reducing antibiotic resistant gene abundance and diversity in domestic wastewater treatment effluents. Well done Pani!!
Professor David Graham joins Professor Dato’ Ir Dr Zaini Ujang (Secretary General to the Environment Ministry of Malaysia) and Professor Azmi bin Aris (Director of Centre for Environmental Sustainability and Water Security, Universiti Teknologi Malaysia) as panellists and moderator for this webinar. Special thank you to Prof Dr Zainura Zainon Noor for leading the event. The webinar took place 17-19 August 2020. View day two of the webinar here.
We are one of the teams on the new £1m research programme seeking to establish an early warning of future outbreaks and reduce reliance on costly testing of large populations. The research programme led by the UK Centre for Ecology & Hydrology (UKCEH), also involves researchers from the universities of Bangor, Bath, Edinburgh, Cranfield, Lancaster, Oxford and Sheffield, plus the London School of Hygiene and Tropical Medicine. Read the news releases from Newcastle University and UKCEH. This work is an extension to our UK and Spanish SARS-CoV-2 Project.
