MALDI-TOF MS reference library of various microbial strains
under the NBRP Fundamental Technology Upgrading Program
JCM, IFM, GTC, and NEKKEN* established a new MALDI-TOF MS reference library ‘EMALiMB’ (Expanded MALDI-TOF MS Library for MALDI Biotyper®) for various microbial strains. You can download the reference data file (.btmsp) via the link below and import it in the software (compatible with Bruker’s MALDI Biotyper®). Depending on your PC environment, errors may occur while importing large .btmsp files. In such cases, please try importing the files in smaller batches by lower taxonomic groups.
EMALiMB_NBRP_Library_ver3.0 provides 2,000 data of the JCM + IFM strains (eukaryotic microbes), ca. 1,140 data of the JCM + GTC strains (prokaryotes), and 14 data of the NEKKEN strains (including Trypanosoma), etc. In this current version, the MALDI-TOF MS data of anaerobes including lactic acid bacteria and intestinal bacteria are available. Please note that the ver3.0 includes the data from the ver2.0.
This project was supported by the FY2020-2021 Fundamental Technology Upgrading Program of National BioResource Project (NBRP) of the MEXT, Japan, and we have been adding MALDI-TOF MS data in the current version of the library. The microbial strains used in this project are available from JCM, IFM, GTC, and NEKKEN.
