Abstract
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 then is subjected to a treatment killing the micro-organisms; whereupon the concentration of the substance is measured anew. The relation between the first and second concentration is used as a measure of the concentration of micro-organisms in the sample.
