Abstract:
A process for the recovery of bacitracin from a fermented beer containing it by adding sodium alkylbenzenesulfonate in the presence of alkaline earth metal ions, separating the precipitate formed thereby,, dissolving in a lower aliphatic alcohol, treating with an ion-exchange resin to remove the alkylbenzenesulfonate, and recovering bacitracin by evaporation. The alkaline earth metal bacitracin alkylbenzenesulfonate complex has antibiotic activity and is useful as such.
