TCF-based fluorescent probe for monitoring superoxide anion produced in bacteria under chloramphenicol- and heat-induced stress

Abstract

We report on a superoxide anion (O₂˙^-) responsive fluorescent probe called TCF-OTf. TCF-OTf is able to monitor O₂˙^- production when the bacterial species <i>Pseudomonas aeruginosa</i>, <i>Staphylococcus aureus</i>, <i>Escherichia coli</i>, and <i>Enterococcus faecalis</i> are exposed to chloramphenicol and heat shock at 50 and 58 °C.
