A novel biotechnology product for the degradation of biofilm-associated polysaccharides produced by Streptococcus mutans.

In this study we evaluated the activity of ABR preparation, a first-in-class agent obtained through fermentation process by genetically unmodified Bacillus spp., in breaking down polysaccharide produced by Streptococcus mutans, primary coloniser of tooth surface and abundant in dental biofilms. Our results showed that ABR preparation is able in degrading sugars formed by S. mutans, both in broth culture and onto teeth surface. Its activity is not influenced by the presence of saliva, commercial mouthwashes or oral disinfectants. ABR preparation has the potential to remove preformed plaque and counteract its development, thus offering conservative control of gingival and periodontal disease.
