Method of detecting microorgan ISMS using labelled electron acceptors

摘要

Provided is a method of detecting microorganisms. The method includes: loading a contaminant sample in a sealed chamber; replacing air in the sealed chamber with air containing isotopically labelled electron acceptors followed by incubation; and comparing the content of metabolites of the electron acceptors for the contaminant sample with that for a standard sample containing no microorganisms, based on isotopic analysis of the air in the sealed chamber.
