  • Glycopeptide recovery process
    Patent number: 4845194
    Abstract: An improvement in the large-scale recovery of vancomycin-type glycopeptide antibiotics which comprises (1) commingling the fermentation medium in which the antibiotic is produced with a polystyrene divinylbenzene resin such as Dow XFS-43278.00, (2) separating the resin from the medium and (3) eluting the antibiotic from the resin. This improvement avoids preliminary filtration and pH adjustment of the broth, simplifies waste-disposal problems and eliminates antibiotic losses due to mycelial adsorption and filtration.
