title: Novel polyether antibiotics X-14873A, G and H produced by a Streptomyces: taxonomy of the producing culture, fermentation, biological and ionophorous properties of the antibiotics.
abstract: Novel polyether antibiotics X-14873A, X-14873G, and X-14873H are produced by the fermentation of Streptomyces sp. X-14873 (ATCC 31679). This report presents taxonomic studies and fermentation conditions for the antibiotic producing culture. The antibiotics are mainly active against Gram-positive bacteria. The ionophore properties of X-14873A are also characterized.
