Xanthan 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 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 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...
متن کاملBiodegradation of Xanthan Gum by Bacillus sp.
Strains tentatively identified as Bacillus sp. were isolated from sewage sludge and soil and shown to elaborate extracellular enzymes that degrade the extracellular polysaccharide (xanthan gum, polysaccharide B-1459) of Xanthomonas campestris NRRL B-1459. Enzyme production by one strain was greatly enhanced when the strain was incubated in a mixed culture. Products of degradation were identifie...
متن کاملConstruction of lactose-utilizing Xanthomonas campestris and production of xanthan gum from whey.
Xanthomonas campestris pv. campestris possesses a low level of beta-galactosidase and therefore is not able to grow and produce significant amounts of xanthan gum in a medium containing lactose as the sole carbon source. In this study, a beta-galactosidase expression plasmid was constructed by ligating an X. campestris phage phi LO promoter with pKM005, a ColE1 replicon containing Escherichia c...
