Hard to Kill Stuff: Radiation and Disinfectant Resistance in Microorganisms

This presentation aims to review the strategies by which microorganisms thrive in extreme radiation environments, extreme temperatures, in contaminated environments, at varying pH and salt levels. Beyond radiation resistance, the mechanisms microorganisms utilize to circumvent biocidal activities will also be discussed. Due to the limited research of such radio tolerant and disinfection resistant microorganisms, the major challenges that lie ahead will  also be  examined.
