Escherichia coli transient response

Chemo- and photostimulation of halobacteria both caused a transient increase in the net rate of demethylation [47]. This increased rate is observed independently of whether the stimulus is an attractant or a repellent. In contrast, Escherichia coli exhibits responses to positive and negative stimuli which consist of a transient decrease and increase in methylesterase activity, respectively [48]. The same demethylation phenomenon as in...
