Method of and apparatus for separating microorganisms from sample using electrodialysis and microorganism capturing means

摘要

Provided are a method and an apparatus for separating microorganisms from a sample. The method includes: introducing the sample into a reaction chamber of an apparatus for controlling a concentration of salts, the apparatus comprising the reaction chamber defined between a cation exchange membrane and an anion exchange membrane, a first electrode chamber defined between the anion exchange membrane and a first electrode and containing an ion exchange medium, and a second electrode chamber defined between the cation exchange membrane and a second electrode and containing an ion exchange medium; applying a voltage between the first electrode and the second electrode to electrodialyze the sample in the reaction chamber, thereby reducing the concentration of salts in the sample; and allowing the sample having the reduced concentration of salts to contact a microorganism capturing means, wherein the sample is a biological sample.
