Production of Exopolysaccharides

1998
A broad variety of bacteria including the Rhizobiaceae are able to secrete polysaccharides. Sugar polymers that form an adherent cohesive layer on the cell surface are designated capsular polysacharides (CPS), whereas the term exopolysaccharide (EPS) is used for polysaccharides with little or no cell association.

Analysis of bacterial exopolysaccharides

Biotechnology and Applied Biochemistry, 1987
Extracellular polysaccharides have been isolated from cultures of freshwater and marine bacteria originally isolated from material adhering to surfaces and underivatized hydrolysates have been analyzed by high‐performance liquid chromatography methods.

Exopolysaccharide Quantification

2014
The extracellular (EC) matrix is a key feature of mature P. aeruginosa biofilms. Exopolysaccharides are considered as major components of this biofilm matrix. They include alginate, LPS, glucans, and psl- and pel-dependent products. Here, we describe a method of quantification of the psl-dependent mannose-rich exopolysaccharide, based on the ...

Marine-Derived Exopolysaccharides

2015
The marine biotechnologies still remain a new and emergent science which is closely linked to the marine biodiversity and to the technological capacities to investigate more atypical ecosystems. Marine microorganisms show unique biodiversity since they have to adapt to various marine environmental conditions such as low or high temperatures, alkaline ...

New perspectives for Lactobacilli exopolysaccharides

Biotechnology Advances, 2011
Lactobacilli have the ability to produce different kinds of exopolysaccharides (EPS) exhibiting a wide diversity of structures. EPS are classified, according to their composition into homopolysaccharides and heteropolysaccharides. One of their most described applications is their utilization as texturing agents naturally synthesized in the fermented ...

EXOPOLYSACCHARIDES IN PLANT-BACTERIAL INTERACTIONS

Annual Review of Microbiology, 1992
Rhizobial plant symbionts and bacterial plant pathogens produce exopolysaccharides that often play essential roles in the plant interaction. Many of these exopolysaccharides are acidic heteropolysaccharides that have repeating subunit structures with carbohydrate and noncarbohydrate substituents, while others are homopolysaccharides such as alginate ...

Biosynthesis of Microbial Exopolysaccharides

1982
Publisher Summary This chapter surveys current knowledge of the production and synthesis of microbial exopolysaccharides. Although the emphasis is on bacterial polymers, relevant information is included on similar products from yeasts, fungi, and other eukaryotes.

Exopolysaccharides of Agrobacterium tumefaciens

2018
Agrobacterium exopolysaccharides play a major role in the life of the cell. Exopolysaccharides are required for bacterial growth as a biofilm and they protect the bacteria against environmental stresses. Five of the exopolysaccharides made by A. tumefaciens have been characterized extensively with respect to their structure, synthesis, regulation, and ...

Adhesive Bacterial Exopolysaccharides

2016
Exopolysaccharides promote adhesion of bacteria to biotic and abiotic surfaces and are a key component of the extracellular matrix of many biofilms. Exopolysaccharides are chemically and structurally diverse and confer considerable advances to the bacteria that produce them. The increased tolerance to antibiotics and resistance to environmental changes

Exopolysaccharides from Lactic Acid Bacteria

2007
Carbohydrates are an important part of life and are present in bacteria, fungi, viruses, yeast, plants, animals and humans. The rapid expansion of chemistry and glycobiology over the last few years has provided many new, imaginative and efficient techniques which provide further insight into the structures and biological interactions of carbohydrates ...
