Priority changes between biofilm exopolysaccharides synthesis and rhamnolipids production are mediated by a c-di-GMP-specific phosphodiesterase NbdA in Pseudomonas aeruginosa

iScience, 2022
Summary: The synthesis of biofilm exopolysaccharides and rhamnolipids (RLs) are two interrelated processes in Pseudomonas aeruginosa, but how bacteria coordinate these two processes remains unclear. We collected a P.

Exopolysaccharides Derived from Probiotic Bacteria and their Health Benefits

Journal of Pure and Applied Microbiology, 2023
Probiotic bacteria are producers of secretory products such as bacteriocins and polysaccharides. Both homopolymeric and heteropolymeric exopolysaccharides (EPS) present on the surface of microorganisms have shown beneficial properties.

Microbial Exopolysaccharides as Drug Carriers [PDF]

Polymers, 2020
Microbial exopolysaccharides are peculiar polymers that are produced by living organisms and protect them against environmental factors. These polymers are industrially recovered from the medium culture after performing a fermentative process. These materials are biocompatible and biodegradable, possessing specific and beneficial properties for ...

Modulation of Lipoteichoic Acids and Exopolysaccharides Prevents Streptococcus mutans Biofilm Accumulation

Molecules, 2020
Dental caries is a diet–biofilm-dependent disease. Streptococcus mutans contributes to cariogenic biofilms by producing an extracellular matrix rich in exopolysaccharides and acids.

Imaging flow cytometry reveals a dual role for exopolysaccharides in biofilms: To promote self-adhesion while repelling non-self-community members

Computational and Structural Biotechnology Journal, 2022
In nature, bacteria frequently reside in differentiated communities or biofilms. These multicellular communities are held together by self-produced polymers that allow the community members to adhere to the surface as well as to neighbor bacteria.

Exopolysaccharides Produced by Lactobacillus rhamnosus KL 53A and Lactobacillus casei Fyos Affect Their Adhesion to Enterocytes [PDF]

Polish Journal of Microbiology, 2018
Probiotics promote and help to maintain beneficial microbiota composition of the gastrointestinal tract ecosystem and have a positive impact on the host’s health. Production of exopolysaccharides is an important feature of probiotic lactobacilli.
