Cell thermosensitivity of Escherichia coli B/r increases with the cooling rise, especially in hypertonic
conditions after heating at 50, 55 and 60 °C. A certain relationship is suggested between the observed phenomenon and the osmotic
homeostasis system of microorganisms under condition of thermogenic and tonic stress.
