Electrical Spiking in Escherichia coli Probed with a Fluorescent Voltage-Indicating Protein
Joel M. Kralj; Daniel R. Hochbaum; Adam D. Douglass; Adam E. Cohen
<jats:title>Introducing Bacterial Electrophysiology</jats:title> <jats:p> Bacterial electrophysiology has been limited by the inability to measure the membrane potential of single cells. <jats:bold> Kralj <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" page="345" related-article-type="in-this-issue" vol="333" xlink:href="10.1126/science.1204763">345</jats:related-article> ) engineered a class of voltage-sensitive fluorescent membrane proteins to perform electrophysiological measurements on individual intact bacteria. These measurements showed that <jats:italic>Escherichia coli</jats:italic> generate electrical spikes, reminiscent of action potentials in neurons. The response of electrical spiking in bacteria was assessed in response to a wide range of physical and chemical perturbations, and was correlated with efflux activity. In the future, the probe should be useful in determining the roles of membrane potential in a variety of medically, environmentally, and industrially important bacteria. </jats:p>
