For 40 years, IFF have been collecting thousands of phages and bacterial strains from all across the globe. This library of unparalleled biodiversity has helped us understand the phage-host relationship and determine specific phage-resistance mechanisms, which enables us to proactively increase the phage resistance of our strains. We apply our knowledge of phage-host relationships to design a series of starter cultures with increased phage robustness and define their use in rotation to prevent the outbreak of phage. Should phage appear, our research has shown us how to increase phage robustness and resilience. If you’d like to learn more, please visit: iff.com/food.
