“…Cell exposure to high temperatures results, among other effects, in DNA and membrane damage ( SEDWICK and BRIDGEs 1972, WOODCOCK and GRIGG 1972, HITCHENER and EGAN 1977, TSUCHIDO et al 1985 and in induction of the HS stimulon (NEIDHARDT et al 1984, CHUANG andBLATTNER 1993). Heat treatment of Escherichia coli cells in the range of 50 "C to 52 "C induce DNA single-and double-strand breaks and changes in the sedimentation properties of the nucleoid ( SEDWICK and BRIDGES 1972, WOODCOCK and GRIGG 1972, PELLON et al 1980. DNA breaks are also present at 46 "C and even at lower temperatures (PAULING and BECK 1975).…”

Escherichia coli cells exposed to high temperatures exhibit a progressive loss of viability. We observed two mechanisms of cell death induced by lethal temperatures: with and without lysis. The number of cells lysed by heat decreased at later stages of the growth curve, when cells were pre-treated at lower temperatures for 10 minutes and when cells were pre-treated with novobiocin, nalidixic acid and cadmium chloride. Cell lysis was similar in wild type, rpoH, groE and dnaK mutant cells as well as in cells which overproduce heat shock proteins GroE or DnaK. Results using cells aligned for cell division and cells growing at 42 degrees C, 45 degrees C and 47 degrees C suggest that cells near division are more sensitive to lysis and that a high concentration of heat-shock proteins increases their resistance to lysis.
