Optimization And Production Of Xanthan Gum By Xanthomonas Campestris NRRL-B-1449 From Sugar Beet Molasses
-----------------------------------------------------ABSTRACT----------------------------------------------------Xanthan gum is a natural polysaccharide having an industrial importance. It is commonly called as heteropolysaccharide which is produced by Xanthomonas campestris. In the present investigation Xanthan gum fermentation by local isolates of Xanthomonas campestris NRRL-B-1449 from sugar...
متن کامل(Poly)Saccharides in cosmetic products – From alginate to xanthan gum
he prefix “poly” makes us think of synthetics which are formed by polymerization of smaller units (monomers). As a matter of fact, polysaccharides are biopolymers composed of differently linked single sugar molecules. As a result the characteristics of the sugars completely change. The best known monomer sugars (monosaccharides) are glucose (dextrose, grape sugar), fructose and galactose. Monos...
متن کاملProduction of xanthan gum from soybean biodiesel: a preliminary study
Background Xanthan gum, a commercial microbial polysaccharide, has many industrial applications, including the tertiary recovery of oil, due to its unique rheological behavior (e. g. high viscosity at low concentrations, pseudoplasticity, solubility, stability over a wide range of pH values and temperatures, compatibility with many salts) [1]. Its production employs glucose or sucrose, which ra...
متن کاملXanthan gum: production, recovery, and properties.
Xanthan gum is a microbial polysaccharide of great commercial significance. This review focuses on various aspects of xanthan production, including the producing organism Xanthomonas campestris, the kinetics of growth and production, the downstream recovery of the polysaccharide, and the solution properties of xanthan.
متن کاملXanthan gum and colonic function in man.
It was with interest that I read this paper, which looks at the effect of feeding xanthan gum on colonic function in man. The authors look at whether it is possible to predict the laxative effect of a polysaccharide from its fermentation characteristics in vitro, as proposed by Adiotomre et al. (1990). However, the authors have not used the methodology used in the Adiotomre paper and, therefore...
