PMEU (Portable Microbe Enrichment Unit) acts as an analytical tool on the first steps of microbial detection chain (sampling, sample preparation, enrichment) and is compatible with all methods used for further analysis and characterization. Enrichment procedures for water samples recover weak or environmentally stressed bacterial cells and improves the quality of microbiological cultivations. Enrichment of both aerobic and anaerobic microbial flora can be started immediately at the sampling site which speeds up the result generation. Microbes have a crucial role in the cycles of organic and inorganic compounds in ecosystems, and consequently in entire paper making process. PMEU methods help to develope both the control and the research of these cycles significantly.
The enhanced recovery of microbial metabolism by PMEU procedures facilitates the control of microbial contamination of natural water resources as well as of tap, drinking and recreational waters. This enhanced and improved recoverability in the PMEU methods is of particular importance in numerous and frequent cases where microbes are suffering from environmental stresses. Microbe load and pollution of process and waste waters as well as in swimming pools, beaches, jacuzzis and natural waters can be mapped and fingerprinted reliably in all conditions. . In addition to microbiological contamination, chemical and toxic pollution can be revealed on high sensitivity level by PMEU SCENTRION equipment.
Purity control of industrial water circulations, having a great economic role in the manufacture of P&P products, can be performed rapidly and easily using PMEU methods. . Potential environmental disadvantages of the industrial production can thus be prevented already during the processes. This also leads to higher quality of the products.
Key Account Director of SAMPLION Ltd., Microbiologist Juha V. Mentu, has been involved in the validation of several ISO/SFS standard method applications for PMEU whic are applicable also in P&P microbiology. He has also developed PMEU-based methods for biocide testing and control of process biofilms.
