Abstract
1462442 Purification of patricin SPA SOC PRODOTTI ANTIBIOTICI SpA 27 Aug 1975 [29 Aug 1974] 37773/74 Heading C2A A process for the recovery of patricin comprises adding a surface-active agent to a fermented liquor containing patricin in an amount sufficient to bring the patricin into solution, removing insoluble material and recovering patricin from the aqueous solution. The surface active agent may be a cationic agent such as an alkyl aryl ammonium salt, or an anionic agent such as an alkali metal alkyl sulphate. The patricin may be recovered by precipitation from solution by the addition of a metal salt, suitably an alkaline earth metal salt. The surface-active agent may be removed from the precipitated patricin by treatment with a suitable solvent or with a surface-active agent of the opposite type to that initially used. Alternatively the patricin may be isolated from the treated fermentation liquor by treatment with at least 5% by volume of a solvent which is water-immiscible and with a surface-active agent of the opposite type to that initially used. The patricin isolated by these methods may be further purified by solubilization followed by reprecipitation upon the addition of a non- solvent for patricin.
