The invention relates to a microbial test standard for use in infrared spectrometry which has at least two resealable vessels which are liquid-tight when closed, each of which contains a predefined amount of dried biomass of a microorganism. The microorganisms in the different vessels differ in at least one characteristic, which is selected in particular from the group comprising species, subspecies, strain, serovar, pathovar, toxivar and variety, and the difference manifests itself in a predefined intermicrobial spectral distance. The disclosure furthermore comprises a method of using the microbial test standard. |
