Escherichia coli exposed to biocides (antiseptics and disinfectants)

We compared the exposure of E. coli MG1655 to ten commonly used antiseptics and disinfectants for short (30min) and long (7-12h) term, looking for common and unique stress response elements. E. coli MG1655 was exposed to one out of ten biocides (antiseptics and disinfectants) for long (7-12h) term, in triplicate. Controls for this group (no exposure) are also in triplicate. In addition, E.coli was exposed to one out of three biocides for short term (30min). Controls for this group are also in triplicate.
