Abstract

The chemotaxis is a phenomenon to take action with the directionality for the concentration gradient of the existing specific chemical substance around a straight object. It is known to Escherichia coli to have positive chemotaxis for aspartic acid, and cadmium ion is originally a negative chemotactic factor for Escherichia coli. Our team devised the system which collected an existing cadmium ion using chemotaxis of Escherichia coli underwater.
