The effects of heat-stress kinetics on the viability of Escherichia coli were investigated. Cells
were exposed to heat-stress treatments extending from 30 to 50° C, with either a slope (40 …

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 …

Treatment of Escherichia coli with non-lethal doses of heat or benzyl alcohol (BA) causes
transient membrane fluidization and permeabilization, and induces the rapid transcription of …

Aims This study investigates the cell physiology of thermally injured bacterial cells, with a
specific focus on oxidative stress and the repair mechanisms associated with oxidative …

Glucose-or nitrogen-starved cultures of Escherichia coli exhibited enhanced resistance to
heat (57 degrees C) or H2O2 (15 mM) challenge, compared with their exponentially growing …

The natural living style of Escherichia coli occurs in the gastrointestinal tract, where most of
its existence is spent under anaerobic conditions and in stationary phase of growth. Here we …

Temperature downshifts of Escherichia coli throughout its growth range resulted in transient
growth inhibition and a cold shock response consisting of transient induction of several …

Aims: When subjected to dynamic temperatures surpassing the expected maximum growth
temperature, Escherichia coli K12 MG1655 shows disturbed growth curves. These irregular …

Acid-adapted bacterial cells are known to have enhanced tolerance to various secondary
stresses. However, a comparison of heat tolerance of acid-adapted and acid-shocked cells …

The aim of this study was to evaluate the effect of heat stress in in vitro conditions on the
induction of heat-shock protein (Hsp) 70 by Escherichia coli cells, and to determine the …
