Abstract
Cronobacter spp. are high acid resistance pathogens classified as Class A pathogens in powdered infant formula. Herein, we investigated the function of Cronobacter luxS in acid response. Results showed that luxS significantly increased the resistance to acid, demonstrating bacterial survival, bacterial morphology and biofilm formation. Furthermore, LuxS might enhance acid response by mediating the up-regulation of 5-methyltetrahydropteroyltriglutamate–homocysteine S-methyltransferase and homocysteine S-methyltransferase and the down-regulation of methionine adenosyltransferase in the quorum sensing pathway. Therefore, the quorum sensing pathway mediated by luxS is the key control target for Cronobacter survival in acidic environments.
期刊介绍：
The International Journal of Dairy Technology ranks highly among the leading dairy journals published worldwide, and is the flagship of the Society. As indicated in its title, the journal is international in scope.
Published quarterly, International Journal of Dairy Technology contains original papers and review articles covering topics that are at the interface between fundamental dairy research and the practical technological challenges facing the modern dairy industry worldwide. Topics addressed span the full range of dairy technologies, the production of diverse dairy products across the world and the development of dairy ingredients for food applications.
