[Purification of antibiotics by ultrafiltration through semi-permeable membranes].
The process of purification of benzylpenicillin, penicillin V and erythromycin solutions with the use of semi-permeable membranes was studied. Practically complete separation of high-molecular admixtures and microbial colonies and separation of significant amounts of the colored compounds were shown to be possible. The purification process may be used effectively at the early stages of antibiotic production.
