“…In essence, the interaction between light and the PS, generates reactive oxygen species (ROS) through either electron transfer (type I) or energy transfer (type II) reactions. These ROS will react with many cellular components that will induce oxidative processes leading to cell death (Bonnett 2000, Maisch 2009, Ergaieg et al 2008, Tavares et al 2011, Costa et al 2013, Wainwright et al 2017. The great advantage of this methodology is the unlikelihood of the microorganisms to develop resistance mechanisms since there is not a particular target in the cell and also the PS don't have to accumulate in its interior to be efficient (Dahl et al 1989, Tavares et al 2010, Costa et al 2011a, Preuß et al 2013, Alves et al 2014a.…”

“…and E. coli [Sciacca, et al, 2010]. Ergaieg et al (2008) have reported the photoinactivation of Gram-positive and Gram-negative E. coli using porphyrin derivatives and have also discussed the different mechanisms (Types I and II) involved in the phototoxicity of their photosensitizer. Other methods for water decontamination use natural or artificial solar irradiation and TiO 2 nanoparticles to promote the photodegradation of different chemicals (Schüler, et al, 2013;Vilela et al, 2012;Rengifo-Herrera et al, 2010).…”

“…Um desses métodos é a inativação fotodinâmica de micro-organismos (LUKSIENE;PECIULYTE;LUGAUSKAS, 2004;CALIM;PARASCA, 2009). Esta técnica representa uma ótima alternativa para a destruição de células microbianas, e em vista disso as porrinas e compostos relacionados se apresentam como fotossensibilizadores com efeitos citotóxicos efetivos contra os micro-organismos em geral (ERGAIEG et al, 2008).…”
