Carriomycin, a new polyether antibiotic, was isolated from culture broth of Streptomyces hygroscopicus strain T-42082. It is active against Gram-positive bacteria, several fungi, yeasts and mycoplasma. It is also coccidiostatic. The free acid of carriomycin occurs as colorless prisms having the molecular formula C47H80O15 (M.W. 885.15), m.p. 120-122°C and [α] 25D1 -0.5 in methanol. It has no characteristic absorption maxima in the ultraviolet spectrum. The presence of one carboxyl and three methoxy groups was observed from its infrared, PMR and CMR spectra.
