Escherichia coli grown at pH 9·0 was much more resistant to extremes of alkaline pH (10·5–11·5) than when grown at pH 7·0. This is termed habituation to alkali. It was not due to ability to reduce the pH of the medium during exposure but was due to a phenotypic change during growth at pH 9·0. Habituation occurred within 60 min at pH 9·0.
