Characterization of new exopolysaccharide production by Rhizobium tropici during growth on hydrocarbon substrate
(2017-03-01)
Exopolysaccharide (EPS) are produced by a diverse of rhizobia species and has been demonstrated to be a bioemulsifier with potential applications in the degradation of hydrocarbons. In the present study, attempts were made ...
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 ...
Optimization of culture conditions for exopolysaccharides production in Rhizobium sp. using the response surface method
(Pontificia Universidad Católica de Valparaíso, 2006)
The Influence of Cooper and Chromium Ions on the Production of Exopolysaccharide and Polyhydroxybutyrate by Rhizobium tropici LBMP-C01
(2019-03-15)
The influence of bivalent copper (Cu 2+ ) and hexavalent chromium (Cr 6+ ) ions on exopolysaccharide (EPS) and polyhydroxybutyrate (PHB) production by the bacterium Rhizobium tropici LBMP-C01 was investigated. The partial ...
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 ...
Semi-defined media for the exopolysaccharide (EPS) production by Lactobacillus helveticus ATCC 15807 and evaluation of the components interfering with the EPS quantification
(AVA-Verlag, 2000-12)
Growth and exopolysaccharide (EPS) production by Lactobacillus helveticus ATCC 15807 was evaluated in semi-defined media. Lactose (as carbon source) and CaCl2 proved to be the major stimulating factors for an optimal EPS ...
A simple method to evaluate biofilm formation in exopolysaccharide-producing strains of Sinorhizobium meliloti
(Inst Biology, 2019-02)
Sinorhizobium meliloti is a bacterium of great agroeconomic importance because of its ability to fix atmospheric nitrogen in symbiotic association with alfalfa (Medicago sativa) roots, and it is often used in model studies. ...
Draft genome sequence of lactobacillus fermentum Lf2, an exopolysaccharide-producing strain isolated from argentine cheese
(American Society for Microbiology, 2018-11)
Lactobacillus fermentum Lf2, an Argentine cheese isolate, can produce high concentrations of exopolysaccharides (EPS). These EPS were shown to improve the texture and rheology of yogurt, as well as to play a protective ...
