MALDIBIOTYPER®用于水测试
The MALDI Biotyper®(MBT) system accurately identifies and confirms cultivated waterborne pathogens and quality indicators within minutes, enabling water suppliers to preserve environmental and drinking water from serious contamination events. Based on Matrix-Assisted Laser Desorption/Ionization Time-Of-Flight Mass Spectrometry (MALDI-TOF MS), water microbiology laboratories can generate protein ‘fingerprints‘ of microorganisms, to identify potentially pathogenic species.

características
快速确认病原体和质量指标
MBT可以一次性地可靠地测试多个菌落，从而节省了大肠菌群确认的关键时间，E. coli,Pseudomonas aeruginosa,Salmonellaspp.,Enterococcus属，硫酸盐还原厌氧菌（Clostridium), and other environmental contaminants. Fast confirmation results facilitate quick decision making, to ensure the quality and safety of water.
Accurate identification of cultivated waterborne pathogens and quality indicators
The identification of bacterial isolates at the species level enables the characterization of biofilms in drinking water distribution, cooling water systems and towers. MALDI-TOF MS provides a rapid, simple mode of identification, and facilitates a clear representation of the exact species of Legionella and other microbes present in a range of water systems.
Microbial ‘fingerprinting’
The MALDI Biotyper®使用MALDI-TOF MS技术创建微生物的独特蛋白质组学“指纹”，以通过将“指纹”峰值与数千个参考光谱匹配，以准确而可靠的识别。
Broad coverage of microorganisms
The MALDI Biotyper®is capable of detecting over 3,000 different bacteria and fungi species from a range of genera. Water testing laboratories can also continuously expand their own library with home-made reference spectra, thanks to the open library concept. The robustness of MALDI-TOF MS technology confers highly reproducible results, providing confidence in identifications, as well as the possibility of contributing to taxonomic and epidemiological studies.
Saving crucial time
By removing the need for confirmation of presumptive positive screening, the overall turnaround time of analysis for a range of microorganisms can be greatly reduced. Current industry standard methods for the confirmation of presumptive positive samples can take 1-2 days following incubation, whereas the MALDI Biotyper®confirms within minutes.
The MALDI Biotyper®workflow does not require a purification step, saving more than 24 hours forSalmonella, Pseudomonas aeruginosa和quality indicators such as coliforms,E. Coli, Clostridium perfringens和Enterococci。相同的工作流程适用于所有病原体和质量指标测试，使技术人员可以无缝分析多种微生物。
经过验证的技术
MALDI-TOF MS is a recognized technology for the identification of军团菌spp., as specified in the ISO 11731 standard. This approach has also been reviewed by the United Kingdom Accreditation Service (UKAS) and the Drinking Water Inspectorate (DWI), as well as by the German AGROLAB Labor of Eching am Ammersee and Institute of Clinical Microbiology and Hygiene of Regensburg.1
