Abstract
Lactic acid bacteria (LAB) possess immunomodulatory, antioxidant, and antimicrobial properties, making them promising for oral health applications. This study investigated the antibacterial and anti-biofilm activities of TWK10-fermented soymilk extract (TWK10FSEE) against Porphyromonas gingivalis (Pg) and Aggregatibacter actinomycetemcomitans (Aa). TWK10FSEE disrupted the cell membrane integrity, altered membrane permeability, and inhibited the growth of these periodontal pathogens. In a drip-flow biofilm reactor simulating the oral environment, TWK10FSEE regulated biofilm-related gene expression, reduced fimbriae and extracellular polysaccharide production, and retarded biofilm formation. Structural identification revealed succinic acid (SA) and a mixture of daidzein and genistein (MDG) as the primary antimicrobial components. Both SA and MDG effectively inhibited Pg and Aa growth and biofilm formation. TWK10FSEE shows potential as a functional ingredient for periodontal health.
期刊介绍：
Food & Function provides a unique venue for physicists, chemists, biochemists, nutritionists and other food scientists to publish work at the interface of the chemistry, physics and biology of food. The journal focuses on food and the functions of food in relation to health.
