Profile
Outline Activities
We are mainly aiming to improve food safety and guarantee high-quality products by studying on food-born pathogens such as Salmonella, Campylobacter, and Listeria. My study is aiming to evaluate the influence of toxin-antitoxin systems of those bacteria on their stress tolerance and clarify these mechanisms. Especially, my study is focusing on the influence of toxin-antitoxin system on 1) heat stress conditions and 2) injured cells caused by heat treatment. Also, we are working on establishment of novel bacteriophage treatment to control food-born pathogens.
