Temperature sensitivity of bacteriolysis induced by beta-lactam antibiotics in amino acid-deprived Escherichia coli.
The temperature-sensitive penicillin tolerance response previously reported in amino acid-deprived Escherichia coli (W. Kusser and E. E. Ishiguro, J. Bacteriol. 169:2310-2312, 1987) was not due to the induction of the heat shock response resulting from a temperature upshift and was therefore unrelated to the findings of another report (J. K. Powell and K. D. Young, J. Bacteriol. 173:4021-4026, 1991) indicating a positive correlation between the expression of heat shock proteins and penicillin tolerance. The thermosensitive event occurred in the lysis induction stage.
