Production of Exopolysaccharides
1998A 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.

Yeast exopolysaccharides and their physiological functions
Folia Microbiologica, 2021Mounting evidence indicated the capability of various microorganisms in biosynthesis of exopolysaccharides (EPSs). A wide range of evidence extensively investigated the ability of bacterial species for EPS synthesis and their favorable effects, so little is known regarding yeast species.

Exopolysaccharide Quantification
2014The 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 ...

Biosynthesis of Microbial Exopolysaccharides
1982Publisher 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
2018Agrobacterium 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 ...

EXOPOLYSACCHARIDES IN PATHOGENICITY OF ERWINIA AMYLOVORA
Acta Horticulturae, 1993The genetics of the two major exopolysaccharides of Erwinia amylovora, levan and amylovoran, were determined. Transposon mutants lacking levan synthesis were fully virulent on immature pears and showed retarded fireblight symptoms on shoots of pear seedlings.

New perspectives for Lactobacilli exopolysaccharides
Biotechnology Advances, 2011Lactobacilli 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, 1992Rhizobial 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 ...

Production of an exopolysaccharide by Antarctic yeast
Folia Microbiologica, 2009Psychrophilic Antarctic yeasts produce polysaccharides in different concentrations. According to morphological, cultural, physiological and biochemical characteristics, the best producer strain was identified as Cryptococcus flavus A(51). The highest values for viscosity (59.1 mPa s) and crude polysaccharide productivity (5.75 g/L) were obtained in a ...
