Xanthan gum: production, recovery, and properties

Biotechnology Advances, 2000
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.

Immune responses to xanthan gum I. The characteristics of lymphocyte activation by xanthan gum

European Journal of Immunology, 1983
AbstractXanthan gum (XG), a microbial polysaccharide produced extracellularly by fermentation of Xanthomonas campestris, has unique physical properties. We studied the effects of XG on murine lymphocytes in vitro and found that XG induced both a significant increase of DNA synthesis in mouse splenic B cells and thymocytes as well as polyclonal IgM and ...

Rheology of Xanthan Gum

Journal of Rheology, 1978
Rheology of aqueous solutions of xanthan gum was studied over a wide range of shear rate and concentration. At sufficient dilution and low shear rates xanthan solutions show a region of Newtonian viscosity behavior. More concentrated solutions appear to show a yield stress.

Interaction of Xanthan Gum with Suspended Solids

Journal of Pharmaceutical Sciences, 1981
Xanthan gum was adsorbed significantly by magnesium carbonate, aluminum hydroxide, zinc oxide, and calcium carbonate, giving Langmuir-type isotherms. Saturation adsorption was higher from 0.9% NaCl than from water due to reduced mutual repulsion of polymer segments in the presence of the salt.

Stabilization of Sulfamerazine Suspensions by Xanthan Gum

Pharmaceutical Research, 1986
Suspensions of sulfamerazine (10%) containing 0.2% docusate sodium were deflocculated because of repulsion between the negatively charged particles. Flocculation was induced by salts or by xanthan gum, which is anionic, in the presence of salts at concentrations below those at which salt flocculation resulted.

The dietary effects of xanthan gum in man

Food Additives and Contaminants, 1987
Following a 7-day control period, 5 male volunteers consumed, on each of 23 consecutive days, a weight of xanthan gum equal to 15 times the current acceptable daily intake (10 mg/kg b.w.) approved by the EEC and by the Joint FAO/WHO Expert Committee on Food Additives; thus, the lightest and heaviest of the volunteers consumed 10.4 g and 12.9 g ...
