  • Procedure for the purification of tiacumicin B
    Patent number: 9045515
    Abstract: The present invention relates to an improved process for the purification of tiacumicin B. Specifically, the invention relates to a simplified, optimised process for the purification of tiacumicin B from a fermentation broth, using chromatography techniques. In particular, the invention relates to a method for purifying tiacumicin B which comprises subjecting a liquid containing tiacumicin B to at least one hydrophobic interaction chromatography step. The process according to the invention is simpler than the processes according to the prior art, and can easily be used on a large scale for commercial production.

  • Process for purifying Tylosin
    Patent number: 4568740
    Abstract: Disclosed is a process for purifying Tylosin by selective adsorption of the fermentation broth previously brought to 7.5-10.0 pH on polymeric resins and by subsequent deadsorption of the purified product with a aqueous-alcoholic or aqueous-acetonic solution and further purification of the eluate by filtration through macroreticular weak anion resins.
