title: A simple rapid method for quantifying microorganisms by their metabolic activity when bound to a specific adsorbent.
abstract: A simple rapid assay for microorganisms is described. An adsorbent capable of binding microbial cells is deposited in a disposable plastic syringe. A sample to be analyzed is drawn into the syringe and the number of attached microorganisms is calculated from their ability to produce metabolites. The smallest number of yeast cells in a given sample was 50,000. Each analysis takes 2.5 h.
