Construction 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...
متن کاملOptimization 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 کاملXanthan 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 کاملXanthan gum production by Xanthomonas campestris pv. campestris 8004 using cassava starch as carbon source
Cassava starch is a main renewable bio-resource with low price and mass production in Guangxi, China. It was used as carbon source in growing Xanthomonas campestris pv. campestris 8004 (Xcc 8004) for xanthan gum production in this study. The xanthan gum yield of gelatinized cassava starch was higher than that of raw cassava starch; the maximal reducing sugar and amylase activity reached 14.30 g...
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...
