Human Saliva Induces Acetoin-Dependent Metabolic Adaptation that Promotes Stress Tolerance in Streptococcus mutans

This study shows saliva induces acetoin-dependent metabolic changes in Streptococcus mutans, enhancing its stress tolerance through oxidative stress protection.

Strain-Level Diversity Decouples Biofilm Architecture, Acidogenic and Aciduric Traits, and Antimicrobial Tolerance in Streptococcus mutans

This study shows that strain-level diversity in Streptococcus mutans affects biofilm structure, acidogenic traits, and antimicrobial tolerance, with no consistent link between biofilm organization and these functions.

Design, Development and Validation of New Fluorescent Strains for Studying Oral Streptococci

The paper develops and validates fluorescent bacterial strains for studying oral streptococci biofilms and interactions.

A Strain of Streptococcus mitis Inhibits Biofilm Formation of Caries Pathogens via Abundant Hydrogen Peroxide Production

This study identifies a Streptococcus mitis strain that inhibits biofilm formation of S. mutans through high hydrogen peroxide production, but is less effective against pre-formed biofilms.
