<p>A process for recovering a lipophilic oligosaccharide antibiotic from an aqueous fermentation broth containing the lipophilic oligosaccharide antibiotic admixed with impurities, by-products and/or suspended solids, comprising: a) combining said fermentation broth with an adsorbent; b) adjusting the pH of the broth to alkaline in order to solubilize the antibiotic in the broth; c) allowing sufficient time for the solubilized antibiotic in the alkaline broth to be adsorbed by the adsorbent; d) adjusting the pH of the broth to about neutral in order to stabilize the antibiotic adsorbed on the adsorbent; and e) separating the adsorbent to which the antibiotic is adsorbed from the broth. A medium for storing an oligosaccharide antibiotic comprising an adsorbent having a lipophilic oligosaccharide antibiotic adsorbed thereon is also disclosed.</p> |
