ALBORIXIN, ANEW ANTIBIOTIC IONOPHORE: ISOLATION, STRUCTURE, PHYSICAL AND CHEMICAL PROPERTIES

Abstract

Alborixin, a polycyclic polyether ionophorous antibiotic, active against Gram-positive bacteria and fungi, was isolated from cultures of a strain of Streptomyces albus. The isolation, structure and physicochemical properties of this antibiotic are reported. Some derivatives have been prepared and their structures and properties are also described in this paper.
