Abstract
The antibacterial activity and mechanisms of Lactiplantibacillus plantarum LP22541 against Staphylococcus aureus in fermented milk were determined here. Results showed L. plantarum inhibited S. aureus in UHT and fermented milk. Non-volatiles and volatiles were identified to contribute to the overall antibacterial activity of L. plantarum. The addition of manganese to fermented milk restored S. aureus growth, demonstrating that manganese depletion played a key role in the anti-S. aureus activity. Our findings developed a promising bioprotective culture and provided a strategy to suppress S. aureus in a non-bactericidal manner in dairy products.
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.
