METHOD FOR THE DETERMINATION OF THE CONCENTRATION OF MICRO-ORGANISMS

摘要

The concentration or amount of living micro-organisms in a liquid sample can be determined in a reliable manner by determining the concentration of a substance, secreted by the micro-organisms, in the sample, which sample the is subjected to a treatment killing the microorganisms, whereupon the concentration of said substance is measured anew. The relation between the first and second concentration is used as a measure of the concentraion of micro-organisms in the sample.
