Abstract
Cephamycin C is concentrated and purified by subjecting a fermentation broth which contains Cephamycin C to the following sequence of steps: filtration at acidic pH, adsorption of filtrate on activated carbon, removing the adsorbed antibiotic by contacting the carbon with a mixture of water and a polar organic solvent, contacting the eluate with an anion exchange resin, and eluting the resin with a salt solution at a pH of from about 5.5 to about 10.
