    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: Disclosed is a method for selecting a mutant strain belonging to the genus Streptomyces which is a hyper-producer of Streptovaricin C superior to those know heretofore. This is accomplished by first subjecting a natural strain of Streptomyces spectabilis to conditions so as to isolate organisms which are streptovaricin resistant. The streptovaricin resistant organisms thus isolated are then subjected to mutagenesis and then cultured. The colonies which are asporogenous are individually cultured in fermentation batches such that the strains take the form of pellets of varying sizes and colors. From the batch having the most heterogeneous mixture of pellets, the smallest pellet or the pellet(s) having the deepest color (usually deep red or crimson) is isolated. We have discovered that the strain of this pellet has a high likelihood of being a hyperproducer of streptovaricin. The strain of this pellet may then be subjected to fermentation conditions to produce streptovaricin. The nutrient broth containing fumaric acid or water-soluble salts thereof, and adsorbent polymer beads and the streptovaricin produced are recovered in the usual manner. In another embodiment, the fermentation may be carried out in a nutrient broth wherein fumaric acid or its water-soluble salts are deliberately excluded to achieve even higher productivity.

    摘要: A method for separation and recovery of polymeric beads from an antibiotic fermentation broth comprising suspending a mixture of the beads and any inherent mold from the fermentation in an aqueous solution having a specific gravity which is effective to cause the beads to form a discrete layer at or on the surface of the solution, separate and apart from the mold. The separate layer of the beads may then be easily removed from the liquid by a conventional physical methods.
