The stabilisation potential of individual and mixed assemblages of natural bacteria and microalgae [PDF]

, 2010
It is recognized that microorganisms inhabiting natural sediments significantly mediate the erosive response of the bed ("ecosystem engineers") through the secretion of naturally adhesive organic material (EPS: extracellular polymeric substances ...

A Systematic Review of New Trends in Ionic Liquids Applied to Electrolytes on Polysaccharides

, 2022
Polysaccharides are formed by a long chain of monosaccharides, with the main function of promoting energetic and structural reserves for plants and animals. They can be applied as a base of electrolytes, using ionic liquids (ILs) as a solvent base.

Bacterial polysaccharide synthesis and export [PDF]

Current Opinion in Structural Biology, 2016
All domains of life make carbohydrate polymers and by anchoring them to lipid molecules they can decorate the outside of the cell. Polysaccharides are linked to proteins by glycosylation, a process found in both bacteria and in higher organisms. Bacteria do have other distinct uses for carbohydrate polymers; in gram-negative bacteria glycolipids form ...

Potential Antibacterial Activity of Marine Macroalgae against Pathogens Relevant for Aquaculture and Human Health

Journal of Pure and Applied Microbiology, 2017
The exploitation of macroalgal biomass, as a source of antibacterial drugs, would result into the valuable transformation of waste into an economic resource. Ethanol and water extracts or polysaccharides, from nine DNA-barcoded macroalgae (2 Chlorophyta,

Bacterial capsular polysaccharides with antibiofilm activity share common biophysical and electrokinetic properties

Nature Communications, 2023
Bacterial biofilms are surface-attached communities that are difficult to eradicate due to a high tolerance to antimicrobial agents. The use of non-biocidal surface-active compounds to prevent the initial adhesion and aggregation of bacterial pathogens ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
