[New species of the genus Nocardia and its antibiotic properties].

A culture of a new species of Nocardia, i.e. N. indigoensis producing an antibiotic close to celicomycins was isolated from a soil sample of Kazakhstan plated on the selective medium with kanamycin. By a number of chemical properties and biological activity the antibiotic differed from celicomycins. Probably it is a new natural substance.
