Flow cytometry study of Escherichia coli treated with plasma-activated water: confirming the absence of the viable but non-culturable state in bacteria

Ivo Furno, Fabio Avino, Rita Agus, Brayden Graham Myers, Aleksandra Lavrikova

Plasma-activated water (PAW) is an emerging antimicrobial agent with promising applications in bacterial inactivation. The PAW samples are generated by non-contact exposure of deionized water to a surface dielectric barrier discharge plasma and are charact ...

Enhancing solar disinfection (SODIS) with the photo-Fenton or the Fe2+/peroxymonosulfate-activation process in large-scale plastic bottles leads to toxicologically safe drinking water

César Pulgarin

Solar disinfection (SODIS) in 2-L bottles is a well-established drinking water treatment technique, suitable for rural, peri-urban, or isolated communities in tropical or sub-tropical climates. In this work, we assess the enlargement of the treatment volum ...

Catalytic activity of commercial of TiO2 powders for the abatement of the bacteria (E. coli) under solar simulated light: Influence of the isoelectric point

César Pulgarin, Paul Bowen, Juan Kiwi, Damien Gumy, Carlos Morais

Thirteen different commercial TiO2 powders with specific surface areas varying from 9 to 335 m/g and with isoelectric points (IEP) from 3 to 7.5 were investigated for their catalytic activity in E. coli inactivation. The TiO2 samples zeta potential, attenu ...
