Selecting the optimal water quality for microbiology

To ensure accurate results and prevent false positives/negatives and contamination, microbiologists must carefully select their reagents, including water, when preparing liquid or solid culture media. Tap water may contain a range of impurities that could have an impact on bacteria growth or cause various abnormalities of the prepared media, such as incorrect pH, wrong colour or precipitation. Since water is the predominant component of microbiology media formulations, the removal of these contaminants from water is of paramount importance for the preparation of culture media.
