Bruker Daltonics Inc. has announced the Maldi BioTyper system for identification and classification of microorganisms. It analyzes the characteristic protein expression patterns of bacteria, yeasts and fungi via Maldi-Tof mass spectrometry. Starting from a single colony, sample deposition and preparation is performed within five minutes, and no initial assessment, such as gram staining, oxidase tests or PCR primers, is needed. The system’s software implements the data processing steps from raw spectra to peak lists, visualizing the analysis in a graphical user interface. The system is suitable for such applications as taxonomical and infectious disease research, microorganism detection and identification in environmental analysis, food safety and water quality.
