The diagnosis of microbial contaminants can - depending on the task - be carried out at different levels. Among others, the following are used for the primary characterization
- Assessment of the macroscopically recognizable growth behavior also on selective nutrient media
- simple reactions, such as Gram stain, oxidase test
- microscopic methods
For this purpose, a powerful microscope is available, which also allows fluorescence analysis measurements.
Ultimately, a mass spectrometric analysis can help to elucidate the germ identity.
