摘要： A xanthan gum having an improved transmittance is disclosed. Further, the transmittance of the xanthan gum is at least 75% in an 1% by weight aqueous solution. The xanthan gum is prepared by subjecting a strain ATCC 55429 or ATCC 55298 to submerged fermentation conditions to produce a broth containing the gum and debris. The broth is then subjected to heating at a temperature from 45.degree. to 70 .degree. C. for a period of time of at least one half to two hours and at a pH of 9 to 12.5. Two enzyme treatments are performed using an alkaline protease and lysozyme of which the order of their application is irrelevant to the recovery of the xanthan gum. The enzymes are applied at specific temperatures and time periods as well as pH conditions such as a protease is applied at a temperature of 40.degree. to 65 .degree. C. for a period of from 20 minutes to five hours at a pH range of 6 to 10; and the lysozyme is applied at a temperature of 25.degree. to 60 .degree. C. for a period of 20 minutes to five hours at a pH range of 5.5 to 8.0. Both of the enzyme treatments are applied after the broth has been heated in step b) and before the recovery of the xanthan gum.

摘要： A xanthan gum-containing fermented solution is subjected to an enzyme treatment for solubilizing the microbial cells present in the fermented solution. While the fermented solution having undergone the enzyme treatment is maintained at a temperature of 50.degree. C. to 80.degree. C., and xanthan gum is precipitated by adding an hydrophilic organic solvent incapable of dissolving xanthan gum to the fermented solution. When a rotary turbine is used, the precipitate can be cut with a shearing cutter to recover a finely-divided fibrous product.

摘要： A modified xanthan gum has a viscosity of not less than 800 cP as determined on a 0.5% by weight solution thereof in a 12% by weight aqueous sodium chloride solution at 20.degree. C. and a ratio of this viscosity to that determined on a 0.5% by weight solution thereof in distilled water of not less than 1.5. The modified xanthan gum can be prepared by a method comprising the steps of mixing an organic solvent which does not dissolve xanthan gum and is hydrophilic with an aqueous solution of xanthan gum in a mixer, cutting, into fine fibrous materials, deposites formed in the mixed solution together with the mixed solution with a cutter, separating and recovering the suspended fine fibrous materials from the mixed solution and then drying the materials at a temperature of not more than 80.degree. C. The modified xanthan gum can directly be dissolved in aqueous solutions of salts such as common salt even at room temperature and can thus easily show a desired effect of thickening the aqueous salt solutions.

摘要： Pullulan is precipitated from an aqueous solution by mixing with a hydrophilic organic solvent incapable of dissolving pullulan. Solid pullulan is then separated from the liquid component of the dispersion by feeding the dispersion into a V-type disk press having a pair of discoid screens arranged so that the distance between them decreases as they are rotated. The pullulan dispersion is pressed by the discoid screens, recovering the liquid component through the screens. The resulting low-liquid-content pullulan continues to rotate together with the screens to an outlet, where it is discharged from the press.
