title: [Functional characterization of Pseudomonas batumici 17/20 upon long-term storage].
abstract: Variability of properties and antibiotic activity, as well as cells survival of Pseudomonas batumici 17/20--the producer of batumin (antistaphylococcal antibiotic) after long-term storage under vaseline oil layer have been studied. The main culture-morphological and physiological biochemical properties of the mutant strain have been investigated. It has been shown that storage under vaseline oil allows to preserve high level of antibiotic activity: batumin synthesis by the producer was 150 mg/l. Therewith, the survival of cells decreases by two orders during 5 years of storage. The conditions of strain maintenance have been formulated.
