This study was undertaken to establish a new technology, using anti-listerial peptides, to ensure food safety. Production of an anti-listerial peptide, piscicocin CS526, produced by Carnobacterium maltaromaticum CS526 was regulated with environmental pH. A simple one-step isolation method, based on the adsorption-desorption property to bacterial cells, was developed for piscicocin CS526. A freeze-dried bioactive fermented powder with anti-listerial peptide produced by C.maltaromaticum FS-B was effective for the control of L.monocytogenes in a food model at refrigeration and frozen temperature, suggesting that the fermented powder will be a powerful tool to ensure food safety against L.monocytogenes contamination in foods such as ready-to-eat products.

本研究旨在建立一种利用抗李斯特肽的新技术，以确保食品安全。以环境ph为调控条件，对maltaromatium Carnobacterium CS526产piscicocin CS526进行了研究。利用piscicocin CS526对细菌细胞的吸附-解吸特性，建立了piscicocin CS526的一步分离方法。在冷冻和冷冻温度条件下，对含抗李斯特菌肽的冷冻干燥生物活性发酵粉对食品模型中的单核细胞增生李斯特菌具有有效的控制作用，表明该发酵粉将成为保证即食食品中单核细胞增生李斯特菌污染的有力工具。
