The photoinactivation of Pseudomonas fluorescens by endogenous photosensitizers: an overview


Pérez Santin, David  


Pseudomonas is a widespread genus gramm-negative bacteria that are very prevalent and ubiquitous. Their diverse metabolism has allowed them to colonize all kinds of environments. From these species, Pseudomonas fluorescens stands out as one of the main culprits of food spoilage. Due to its ability to form biofilms and grow at 4ºC these bacteria are very challenging to eliminate and they cost the food industry millions of dollars annually. Photodynamic therapy using endogenous photosensitizers has been recently gaining traction as a way to bypass bacterial resistance to antibiotics. This study is an overview of the use of photodynamic therapy as a method of disinfection for the food industry, and presents a small experimental design that would have been carried out if the conditions had allowed it.
