| Abstract: | The stability of the tobramycin-producing organism was studied by the property of the antibiotic production. The organism was stored under conditions of different exposures to light and subculture on slants. The culture was also subjected to long-term storage with various methods. The organism was stable in preserving its antibiotic activity for 1.5 months when stored on the Gauze organic agar No. 2. Subcultures of the organism on this medium provided preservation of the antibiotic activity throughout 4 passages. The culture storage on millet provided preservation of the antibiotic activity for 6 months. |
