ABSTRACT:
A method and apparatus for detecting a toxin whereby a yeast culture is monitored for the release rate of one or more metabolic products before and after the inclusion of a test sample and a decrease in the release rate of the metabolic products indicates the presence of a toxin on the test sample. The method contemplates the use of carbon dioxide-free air as a scrubbing gas to remove carbon dioxide from the media for testing.
