Abstract
There is disclosed an apparatus, a device, and a method using the inventive device and apparatus for the sequential enrichment of a particular microorganism to a threshold level to allow for its detection. The use of the apparatus for sequential microbial enrichment shortens the time period normally spent to enrich samples to permit the growth of enough microorganisms to detect the particular microorganism(s) of interest. The invention eliminates the need for multiple manual transfers of potentially biohazardous materials.
