    摘要： This disclosure provides for xanthan gum polymer, and methods of making thereof, having enhanced properties such as improved hydration tolerance, hydration rates, and/or viscosity properties, as compared to conventional xanthan gum, while maintaining beneficial xanthan gum properties such as enzyme stability and shear stability. The organism used in the fermentation to produce the disclosed xanthan gum typically is a strain of Xanthomonas campestris pathovar campestris. These and other aspects of the xanthan gum are described.

    摘要： The present invention relates to process for reducing the endotoxin content of a sample of fermentation broth containing polysialic acid and endotoxin comprising the sequential steps: (i) adding to the sample a base having a pKa of at least 12 to form a basic solution having a pH of at least 12, incubating the solution for a pre-determined time at a pre-determined temperature; and (ii) recovery of PSA, suitably by (iii) passing the sample through an anion-exchange column whereby polysialic acid is absorbed on the ion exchange resin; (iv) washing the column with one washing buffer, whereby polysialic acid remains absorbed on the ion exchange resin; and (v) eluting the polysialic acid from the column using an elution buffer to provide a product solution of polysialic acid having reduced endotoxin content.
