wyatt technology to eliminate bacteriophage infections in dairy production
|
|
|
wyatt technology’s instruments have been chosen by two french universities to try and identify lactococcus lactis, a bacterium widely used by the dairy industry to eliminate bacteriophage infections in production. bacteriophages are intracellular parasites that multiply inside bacteria, infecting them and causing failures of the milk fermentation process. bateriophage infections several industrial strains are sensitive to powerful bacteriophages, which can infect lactococcus lactis, delay lactic acid production and potentially stop the milk fermentation process: “as a result, the product's desired properties are altered or entirely lost,” said wyatt. “the first step in the infection process is the adsorption of the phage to the bacterial cell. one strategy to minimise bacteriophage infections is to competitively block phage adsorption by adding a protein specifically binding to the phage receptor binding proteins,” the company added. the biological macromolecules joint research unit of the université de provence and université de la méditerranée in france, selected three designed ankyrin repeat proteins (darpins) binding to the baseplate of the lactococcal phage to study. the universities concluded that the darpins could be used as a potential tool to fight against phage and viral infections. wyatt said “the results of the experiment clearly demonstrated that wyatt’s instrumentation allows the study of protein-protein complexes by monitoring complex formation and then accurately characterizing the size and stoichiometry of the resulting assembly.” californian-based wyatt technology is a provider of instruments for macromolecular characterisation. the company develops multi-angle light scattering detectors, working with customers in the biotechnology, chemical, petrochemical, pharmaceutical and academic areas.

despite initiatives such as the rapid alert system for food & feed (rasff), the eu food chain is still vulnerable to malicious activity for the sake of profit or terrorist type activity, according to a leading food safety expert. speaking at the 2011 institute of food technologists (ift) binstead lecture in london, shortly before the current e.coli crisis broke, tony hines mbe from leatherhead food research (lfr) said that the rasff yielded a useful database regarding eu food safety issues.

minneapolis—laboratory testing conducted by the minnesota department of agriculture (mda) and the minnesota department of health (mdh) this week provided additional evidence that the hartmann dairy farm, of gibbon, minn., was the source of a strain of e. coli o157:h7 bacteria that sickened at least five minnesotans after they consumed raw, unpasteurized milk or other dairy products from the farm. mdh reported four cases of illness last week, and a fifth case has subsequently been confirmed in a young child who was not hospitalized.

organic foods have started taking root (no pun intended) in the minds of more and more consumers each year as people strive to live healthier lives.not only do they taste a lot better (without the help of chemicals and flavour enhancers), but they also provide far more nutrients and benefits than their often irradiated and chemically fertilized counterparts. admittedly, organic foods are often more expensive, but the benefits of consuming them are well worth the expense.
