The antimicrobial effects of ultrasonic filed have been studied for years at the phenotypic level, but there is little research to reveal the molecular regulatory mechanisms underlying the phenotypes. In this study, isobaric tag for relative and absolute quantification (iTRAQ) proteome was applied to analyze the regulatory networks of Escherichia coli O157:H7 in response to ultrasonic stress in whole-genome scale. A total of 1856 differentially expressed proteins were identified, of which 1141 were significant up-regulated and 715 down-regulated compared with live control cells. The comprehensive proteome coverage analysis showed that ultrasonic filed influenced various metabolic pathways in..View full abstract
