Since 1986, the FAM offers to the consultant services the possibility to have phages analysed. Methods used for this purpose have been optimised and are, since 1994, integrated in an accredited field. Our experiments have shown that phages participate in most of the starter acidification failures. Although phages have to be tolerated in dairy factories, their massive multiplication has to be efficiently fought. To do so, it is necessary to apply normal hygienic measures and to introduce a quality assuran concept.
Plants and microorganisms can perceive and respond to sound waves. In a review of the literature, Agroscope analysed various publications on this topic. The studies show that sound can lead to positive effects on physiology in the form of improved growth, development and disease resistance.
The war in Ukraine, dry spells and droughts followed by heavy rainfall and flooding are major challenges for our food systems. But the problems that they bring to light are nothing new – and solutions are already to hand.
Biogenic amines in foods represent a health risk. Researchers from Agroscope and INRAE investigated the formation of these undesirable substances in raclette cheeses by the bacterium Morganella morganii.
