Introduction
Library-based MS approaches for microbial identification require labeled sets of microbial mass spectra. Starting with version 0.82 MicrobeMS can deal with experimental MALDI-TOF or LC-MS¹ mass spectra and the respective MS databases.
The RKI databases of microbial MALDI-TOF mass spectra contain mass spectral entries from highly pathogenic (biosafety level 3, BSL-3) bacteria such as Bacillus anthracis, Yersinia pestis, Burkholderia mallei, Burkholderia pseudomallei and Francisella tularensis as well as a selection of MALDI-TOF mass spectra from their close and more distant relatives. The RKI mass spectral databases can be used as a reference for the diagnostics of BSL-3 bacteria using proprietary and free software packages for MALDI-TOF MS-based microbial identification. The databases are distributed as zip archives and contain the original mass spectra in its native data format (Bruker Daltonics). MALDI-TOF MS Databases will be updated on a regular basis.
The LC-MS¹ database is an in silico database which has been compiled from Uni-Prot Knowledgebase (Uni-Prot/KB Swissprot and TrEMBL) resources, for details see below).

LC-MS¹ databases
The original concept of microbial identification by means of MALDI-TOF MS of cultivated microbial cells and spectral distance-based comparison with entries of a microorganism spectra library has been adapted for LC-MS¹ microbial identification, see this preprint: Lasch P, Schneider A, Blumenscheit C and Doellinger J, Identification of Microorganisms by Liquid Chromatography-Mass Spectrometry (LC-MS¹) and in silico Peptide Mass Data, bioRxiv (Dec 10, 2018), doi:10.1101/870089.
