Global genome response of Escherichia coli to water activity downshift

ABSTRACT: In a previous study we adopted an integrated transcriptomic and proteomic approach to determine the physiological response of E. coli O157:H7 Sakai during exponential phase growth under steady-state conditions relevant to low temperature and water activity conditions experienced during meat carcass chilling in cold air (Kocharunchitt et al., 2012). The findings of that study provide a baseline of knowledge of the physiology of this pathogen, with the response of E. coli O157:H7 to steady-state conditions of cold and osmotic stress. To provide an insight into the genetic systems enabling this organism to adapt to growth at low water activity, we extended the aforementioned study to investigate the growth kinetics of E. coli O157:H7 Sakai during abrupt water activity downshift from 0.993 to
