The antibiotic Elaiomycin was isolated from submerged culture filtrates of Streptomyces hepaticus. l The biological action and chemical structure of the antibiotic are unique. Elaiomycin, which was isolated as a distillable oil, has marked activity only against certain virulent and avirulent mammalian strains of tubercle bacilli5 and is shown by this investigation to have the chemical structure I.
