Using of infrared spectroscopy to study the survival and injury of Escherichia coli O157:H7, Campylobacter jejuni and Pseudomonas aeruginosa under cold stress in low nutrient media

► This manuscript has importance to study bacterial cold injury on the molecular basis using vibrational spectroscopy. ► Infrared spectroscopy can monitor the increase of polysaccharides for bacterial resistance to harsh environment, such as cold stress and freezing. ► The bacterial response to cold stress is strain dependent.
