The MALDI Biotyper® system (MBT) provides specific and reliable identification of microorganisms within minutes. It’s recent validation and certification according to the Official Method of Analysis program (OMA) of the AOAC International and according to the new ISO/DIS 16140-part 6 standard, offers now a reliable "one system - one workflow" solution for food microbiology, in terms of safety and quality.
The MBT has been validated as a complete food microbiology solution for confirmation of:
- Cronobacter spp.
- Salmonella spp.
- Campylobacter spp.
- Listeria spp. and Listeria monocytogenes
in accordance with ISO/DIS 16140-6:2017 and the MicroVal Rules and Certification Scheme version 8. The certificates are available on www.microval.org.
The MBT has been certified according to the Official Method of Analysis program (OMA) of the AOAC International, for confirmation and identification of:
- Salmonella spp., Cronobacter spp., Campylobacter spp. and other gram-negative bacteria
First Action AOAC Official MethodSM 2017.09
- Listeria spp., Listeria monocytogenes and other gram-positive bacteria
First Action AOAC Official MethodSM 2017.10
The OMA 2017.09 and 2017.10 protocols are available on http://www.eoma.aoac.org/.
The MALDI Biotyper is a Rapid Microbiological Method for microorganism identification based on proteomic fingerprints, useful in food microbiology. Its workflow has been designed to be as robust and easy to perform as possible. Only a few simple steps are required to generate a high-quality, reliable microorganism confirmation/identification - within minutes after detection of a positive selective culture, and without a time-consuming purification step. These time savings can be directly translated into significant cost savings in terms of lost product shipments and production line uptime.
The annually updated MBT Compass® reference library currently comprises 7,854 reference spectra of 2,748 species from 471 bacteria and fungi genera, including microorganisms important for food and beverage safety and quality controls. A dedicated MBT Filamentous Fungi Library is available as well, expanding the identification capabilities to 152 species / species groups. The reference libraries are not only a reliable source for confirmation of food pathogens or quality indicators such as Salmonella spp., Listeria spp., L. monocytogenes, Campylobacter spp., or Cronobacter spp.; but also allow the quality control of starter cultures and other fermentation, ripening/maturation strains, and the identification of microbial spoilers such as species of Pseudomonadales, Enterobacteriaceae, spore forming bacteria, yeasts and molds.
