Modulation of lipoteichoic acids and exopolysaccharides prevents Streptococcus mutans biofilm accumulation
(2020-05-01)
Dental caries is a diet-biofilm-dependent disease. Streptococcus mutans contributes to cariogenic biofilms by producing an extracellular matrix rich in exopolysaccharides and acids. The study aimed to determine the effect ...
Extracellular DNA and lipoteichoic acids interact with exopolysaccharides in the extracellular matrix of Streptococcus mutans biofilms
(2017-10-21)
Streptococcus mutans-derived exopolysaccharides are virulence determinants in the matrix of biofilms that cause caries. Extracellular DNA (eDNA) and lipoteichoic acid (LTA) are found in cariogenic biofilms, but their ...
CHARACTERIZATION OF EXOPOLYSACCHARIDES PRODUCED BY RHIZOBIA SPECIES
(Soc Brasileira De Ciencia Do Solo, 2015-11-01)
Increasing attention has been given, over the past decades, to the production of exopolysaccharides (EPS) from rhizobia, due to their various biotechnological applications. Overall characterization of biopolymers involves ...
Caracterização química dos géis produzidos pelas bactérias diazotróficas Rhizobium tropici e Mesorhizobium sp.
(Sociedade Brasileira de Química, 2012-01-01)
The exopolysaccharides with characteristics of gel produced by Rhizobium tropici (EPS RT) and Mesorhizobium sp (EPS MR) are acidic heteropolysaccharide composed mainly of glucose and galactose in a molar ratio of 4:1 and ...

The exopolysaccharides with characteristics of gel produced by Rhizobium tropici (EPS RT) and Mesorhizobium sp (EPS MR) are acidic heteropolysaccharide composed mainly of glucose and galactose in a molar ratio of 4:1 and ...
Functionality of exopolysaccharides produced by lactic acid bacteria
(Research Signpost, 2008)
Many strains of lactic acid bacteria (LAB) are able to produce exopolysaccharides (EPS). Depending on their chemical composition, EPS can be classified as homopolysaccharides (HoPS), which contain a single type of ...
Inactivation of Streptococcus mutans genes lytST and dltAD impairs its pathogenicity in vivo
(2019-01-01)
Background: Streptococcus mutans orchestrates the development of a biofilm that causes dental caries in the presence of dietary sucrose, and, in the bloodstream, S. mutans can cause systemic infections. The development of ...
Rhizobia exopolysaccharides: promising biopolymers for use in the formulation of plant inoculants
(Springer, 2022-09-15)
Inoculants with beneficial microorganisms comprise both selected strains and carriers that ensure a favorable microenvironment for cell survival and stability. Formulations of inoculants using synthetic polymers as carriers ...
Screening of lactic acid bacteria isolates from dairy and cereal products for exopolysaccharide production and genes involved
(Elsevier Science, 2007-09-30)
A total of 174 lactic acid bacteria (LAB) strains isolated from dairy and cereal products were screened for the production of exopolysaccharides (EPS). Therefore, a rapid screening method was developed based on ultrafiltration ...
