Abstract
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.
