A method for separation and recovery of polymeric beads from an antibiotic fermentation broth comprising suspending a mixture of the beads and any inherent mold from the fermentation in an aqueous solution having a specific gravity which is effective to cause the beads to form a discrete layer at or on the surface of the solution, separate and apart from the mold. The separate layer of the beads may then be easily removed from the liquid by a conventional physical methods.

In a process for the production of Streptovaricin wherein Streptomyces spectabilis is cultured in a broth to produce a mold and generate an antibiotic in the presence of absorbent polymer beads, and the beads with antibiotic adhered thereto are recovered from the broth, the improvement which comprises adjusting the specific gravity of the broth to a value effective to cause the beads to separate in a layer separate from the mold at the surface of the broth and removing the beads from the broth.
