Bactericidal properties of copper-Tin nanoparticles on Escherichia coli in a liquid environment
(MDPI AG, 2020-09-01)
Article
Accés obertIn this research, copper-tin alloy nanoparticles were made by a mechanical alloying method and were examined by two well-known and common bactericidal tests, optical density, and colony-forming units count in terms of ... -
Elucidating bacterial regrowth: effect of disinfection conditions in dark storage of solar treated secondary effluent
(2014-09-15)
Article
Accés obertIn this study, we systematically investigate solar disinfection of synthetic secondary wastewater, with the effort to decrypt the effects disinfection conditions have on post-irradiation bacterial regrowth in the dark. A ... -
Estudi de la caracterització d'un promotor combinatori en Escherichia coli
(Universitat Politècnica de Catalunya, 2011-08)
Projecte/Treball Final de Carrera
Accés obertEn el present projecte es realitza la caracterització d’un promotor combinatori en Escherichia coli. El promotor combinatori d’estudi, el Plac/ara-1, és sensible a dos proteïnes reguladores diferents que condicionen el ... -
Immobilization of antimicrobial core-shell nanospheres onto silicone for prevention of Escherichia coli biofilm formation
(2016-09-16)
Article
Accés obertEscherichia coli (E. coli) strains are among the most frequently isolated microorganisms in urinary tract infections able to colonize the surface of urinary catheters and form biofilms. These biofilms are highly resistant ... -
Impact of different light intermittence regimes on bacteria during simulated solar treatment of secondary effluent: implications of the inserted dark periods
(2013-12)
Article
Accés obertIn this study, the effect of light intermittence on solar disinfection of secondary treated wastewater was investigated. Synthetic secondary effluent was spiked with Escherichia coli and submitted to 3 different light ... -
Light wavelength-dependent E. coli survival changes after simulated solar disinfection of secondary effluent
(2015-12-01)
Article
Accés obertIn this study, the photoreactivation and the modification of dark repair of E. coli in a simulated secondary effluent were investigated after initial irradiation in different conditions. The simulated solar exposure of the ... -
Monitoring the post-irradiation E-coli survival patterns in environmental water matrices: implications in handling solar disinfected wastewater
(2014-10-01)
Article
Accés obertIn this study, simulated solar disinfection of secondary effluent was followed by dark storage at different temperatures or different receiving water matrices. Escherichia coil illumination was followed by 3-day monitoring ... -

(Universitat Politècnica de Catalunya, 2015-05-26)
Treball Final de Grau
Accés restringit per decisió de l'autor -
Solar disinfection modeling and post-irradiation response of Escherichia coli in wastewater
(2015-12-01)
Article
Accés obertIn this work, an intensive assessment of solar disinfection of secondary wastewater was elaborated in controlled laboratory conditions. Batch tests of Escherichia coli-spiked synthetic secondary effluent, at nine different ... -
Temperature-dependent change of light dose effects on E. coli inactivation during simulated solar treatment of secondary effluent
(2015-04-14)
Article
Accés obertIn this study, simulation of solar disinfection of secondary effluents was performed, to assess the dose effects, as instructed by the reciprocity law. A full factorial experimental design on the operational parameters of ... -
Ultrasound enhancement of near-neutral photo-Fenton for effective E. coli inactivation in wastewater
(2015-01-01)
Article
Accés obertIn this study, we attempt for the first time to couple sonication and photo-Fenton for bacterial inactivation of secondary treated effluent. Synthetic wastewater was subjected to sequential high-frequency/low power sonication, ...
