How bacteria use electric fields to reach surfaces

Electrotaxis is the property of cells to sense electric fields and use them orient their displacement. This has been widely investigated with eukaryotic but it remains unclear whether or not bacterial can an field. Here, a specific experimental set-up was designed form microbial electroactive biofilms while differentiating effect field from that polarised electrode surface. Application during exposure electrodes inoculum shown be required for biofilm afterwards. Similar were formed in both directions result attributed capacity detect K+ Na+ ion gradients creates at should now considered as key factor formation possible implications biomedical domain are discussed.
