Title: Rapid coliform detection system

Abstract: A rapid method for detecting the presence or absence of coliform bacteria in a liquid or liquified dairy sample, for example skimmed milk. A growth medium containing a fluorogenic substrate is combined with the sample and is incubated for a brief period of about 7-9 hours after which a single fluorescence value is measured. Total or thermotolerant coliform bacteria are determined to be present in the sample if the single fluorescent measurement exceeds a predetermined threshold value.
