Xanthan gum is an anionic heteropolysaccharide produced by the bacterium Xanthomonas campestris. Synergistic galactomannan – xanthan gum interactions are used for commercial and technological applications. Prosopis seed gum were mixed with xanthan gum (Sigma, U.S.A) at the following ratios 100/0, 80/20, 60/40, 40/60, 20/80, 0/100 (0.5 % ). Solutions (w/w) were prepared and heated for 1 h. After...

Xanthan gum is exo-polysaccharide, produced by Xanthomonas campestris. Considering a reactor operating in continuous mode, optimum dilution rate is determined by maximization condition. Optimum dilution rate is the dilution rate at which the productivity of xanthan gum is maximum. The current work is focused on implementing an algorithm for design of reactor, having optimum dilution rate as the...

The hierarchical morphology of xanthan solutions is analyzed by light and neutron scattering in a broad range of concentrations in order to connect their morphology to their well-documented dynamic properties. Static light scattering inside the semidilute regime is dominated by the form factor of individual xanthan chains while at higher concentrations chain interconnections appear to modify th...

Background: A number of microorganisms and their enzymes have been reported as xanthan depolymerizers. Paenibacillus species are well-known polysaccharide hydrolyzing bacteria. However, Paenibacillus alginolyticus and Paenibacillus sp. XD are the only species in the genus which are now known to degrade xanthan. Objectives: Complete biodegradation of the xanthan exopolysaccharide is a rarely fou...

The synergistic interaction between xanthan and glucomannan in solution and in the gel phase has been studied by circular dichroism spectroscopy and differential scanning calorimetry. The study in solution of the polysaccharidic mixture indicates a preferred stoichiometry of the interaction corresponding to a weight fraction of xanthan around 0.55. This finding is in reasonable agreement with t...

A novel dual tablet formulation for oral administration using xanthan gum as the carrier and meloxicam as a model drug has been investigated for colonspecific drug delivery using invitro methods. The tablets were evaluated for hardness, thickness, drug content uniformity, and were subjected to invitro drug release studies under conditions mimicking mouth to colon transit and the results of whic...
