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 کاملReactor design strategy : Production of xanthan from sugarcane broth
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...
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 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 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...
