Determination of the microbial count

The microbial count is the number of viable microorganisms in one millilitre or gramme of the material to be examined, e.g. water, soil, milk, ice cream, etc. It is of high practical importance for the analysis of drinking water, soil, and foodstuffs. The
microbial count can only be determined exactly if all of the related tasks are performed in a way that prevents the material that is to be examined from being contaminated with foreign microorganisms.
