Electron microscopy of native xanthan and xanthan exposed to low ionic strength
Biopolymers, 1989AbstractOptical rotation data indicate that xanthan can exist both in an ordered and a disordered conformation. Using molecular weights obtained from light scattering measurements and contour length distributions obtained from electron micrographs, we find that a native, filtered xanthan exposed to low salinity (< 10−4M NaCl) and subsequently ...

Abstract Molecular modelling has been used to show that branching at the 3-position of every second glucose unit in the backbone of the xanthan molecule does not preclude the backbone from adopting a two-fold cellulose-like conformation. A stereochemically acceptable model of this type is defined with a pitch of 10·51 A (slightly longer than that of ...

AbstractXanthan gum, the extracellular polysaccharide from Xanthomonas comperstris, provides aqueous solutions with properties that are extremely useful in a large number of industrial applications, both food and non‐food. These properties, a consequence of xanthan gum's particular molecular shape, are: high at‐rest or low‐shear viscosity even at low ...
