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 ...

EXOPOLYSACCHARIDES IN PATHOGENICITY OF ERWINIA AMYLOVORA

Acta Horticulturae, 1993
The 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.

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 ...

Production of an exopolysaccharide by Antarctic yeast

Folia Microbiologica, 2009
Psychrophilic 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 ...

Exopolysaccharides of Paenibacillus polymyxa: A review

International Journal of Biological Macromolecules
Paenibacillus polymyxa (P. polymyxa) is a member of the genus Paenibacillus, which is a rod-shaped, spore-forming gram-positive bacterium. P. polymyxa is a source of many metabolically active substances, including polypeptides, volatile organic compounds, phytohormone, hydrolytic enzymes, exopolysaccharide (EPS), etc. Due to the wide range of compounds

Bacterial capsular polysaccharides and exopolysaccharides

2010
Bacteria often produce an external layer of polysaccharides, characterized by a definite primary structure, which in turn is responsible for sometimes remarkable physicochemical properties. Although the number of monosaccharides which constitute the polymers is rather low, the great number of different polysaccharides defined up to now shows the ...
