Abstract:
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; ande) separating the adsorbent to which the antibiotic is adsorbed from the broth.
