Sanitation monitoring tool offers better detection
Kikkoman’s LuciPac A3 sanitation system, distributed by Weber Scientific, measures adenosine triphosphate (ATP), which all living organisms contain, as well as monophosphate or diphosphate. The application of bioluminescence for monitoring sanitation and hygiene is a valuable tool for measuring the efficacy of cleaning and sanitation. Bioluminescent systems measure the presence of ATP in a sample using an enzyme system; conventional systems that test for ATP alone may neglect the true presence of contamination.

Flexible module is designed for higher-quality nucleic acids
Thermo Fisher Scientific’s Applied Biosystems MagMAX CORE Mechanical Lysis Module is designed to optimize nucleic acid purification in the detection of Mycobacterium avium subspecies paratuberculosis and other difficult-to-lyse pathogens. MagMAX CORE is a magnetic bead-based universal sample prep solution that can be used to purify nucleic acids from 14 different sample matrices, including milk. The module is optimized for disruption of difficult-to-lyse pathogens and is used upstream from the MagMAX CORE Nucleic Acid Purification Kit to purify nucleic acids from all sample matrices.

Integrated raw milk hygiene test for lower-throughput needs
BacSomatic, an integrated bacteria and somatic cell counter for testing the hygienic quality of milk, is available from Foss. The small automated instrument delivers accurate results for bacteria count and somatic cell count within nine minutes, or two-and-half minutes for somatic cell count alone. It is ideal for use at dairies, on large farms or in smaller milk-testing laboratories. It uses the same approved methods as top-of-the-range BactoScan (bacteria count) and Fossomatic (somatic cell count) milk analyzers, but is designed to match the lower-throughput needs of users requiring as few as 20 tests per day.

Discovery platform offers rapid, rational enzyme selection
Biocatalysts Ltd. worked with The European Bioinformatics Institute to develop a software platform for data analysis called MetXtra. This system for identifying completely novel enzymes rapidly from large metagenomic DNA sequence libraries allows food and dairy researchers to discover unique enzymes quickly for specific applications. MetXtra filters results through bespoke algorithms, encompassing customer specifications and requirements such as solubility, pH and temperature, so the final set of candidate enzymes is targeted specifically to the researcher’s needs.
