The current study examines the desiccation-resistant Ramlibacter tataouinensis TTB310T as a model organism for the production of novel exopolysaccharides and their structural features. This bacterium is able to produce dividing forms of cysts which s

The functional properties of a novel exopolysaccharide (EPS22) produced by Pseudomonas stutzeri AS22 were investigated. EPS22 exhibited non-Newtonian shearing-thinning and predominant gel-like behaviors. Its gel like character showed good pH stabilit

Many bacteria possess a natural ability to synthesize and excrete exopolysaccharides which are widely varied in structure and function. These bacteria have the ability to solubilize inorganic phosphorus, which is important to promote growth and incre

The extraction of polysaccharide fraction (EtOH precipitate) and the fractionation of ethanol-soluble fraction as well as their characterizations were achieved. The EtOH precipitate was extracted from myrtle fruit ( Myrtus communis L.), an edible spe

International audience; Bacterial cells and bacterial exopolysaccharides differ strongly in their respective colloidal and polymeric habits. This suggests different reactivities toward metals and protons, although recent studies point to the similari

Triumfetta cordifolia and Bridelia thermifolia are two shrubs from tropical region of Africa. Their gums are traditionally extracted from fresh barks and used in traditional recipes (thickening and aromatization of sauces, improvement of the swelling

Ionotropic gelation is particularly appealing for the formation of hydrogels because it takes place under mild conditions, is not thermoreversible, and does not involve toxic chemicals. A well-known example is the gelation of alginate in the presence

A systematic study of the synthesis of β- d -glucopyranuronosylamine in water is reported. When sodium d -glucuronate was reacted with ammonia and/or volatile ammonium salts in water a mixture of β- d -glucopyranuronosylamine and ammonium N -β- d

“Ropiness” is a bacterial alteration in wines, beers, and ciders, caused by β-glucan-synthesizing pediococci. A single glucosyltransferase, Gtf, controls ropy polysaccharide synthesis. In this study, we show that the correspondinggtfgene is also

Large amounts of globotriose (Galalpha-4Galbeta-4Glc) are shown to be produced by the high cell density culture of an Escherichia coli strain over-expressing the Neisseria meningitidis lgtC gene for alpha-1,4-Gal transferase. The strain which was dev
