Enhanced acid sensitivity of pressure-damaged Escherichia coli O157 cells

Enhanced acid sensitivity of pressure-damaged Escherichia coli O157 cells

2001

Pressure-damaged Escherichia coli O157 cells were more acid sensitive than native cells and were impaired in pH homeostasis. However differences in acid sensitivity were not related to differences in cytoplasmic pH (pH(i)). Cellular beta-galactosidase was more acid labile in damaged cells. Sensitization to acid may thus involve loss of protective or repair functions.
