Abstract

A method for immobilizing living microorganisms includes a step (1) of disposing a solution containing microorganisms as an electrolyte on the surface of a substrate at least one portion of which is an electrode, and applying a constant potential to the electrode to cause at least a portion of the microorganisms to attach to the surface of the substrate. The constant potential in step (1) is greater than −0.5 V but not greater than −0.2 V (vs Ag/AgCl) or greater than +0.2 V but not greater than +0.4 V (vs Ag/AgCl). The electrolyte in step (1) does not contain a source of nutrition for the microorganisms.
