The Visionary Behind the Institute
The institute's story begins with its founder, Danylo Zabolotny (1866-1929), a renowned scientist whose work in epidemiology and microbiology had already gained international recognition when he established the institute. Zabolotny's vision was to create a dedicated space for the systematic study of microorganisms and their applications for public health and industry. His leadership established the institute's dual focus on both fundamental research and practical applications.

Institutional Growth Amid Political Change
The Institute's development occurred against a complex political backdrop. The National Academy of Sciences of Ukraine itself had undergone several transformations since its establishment in 1918, originally as the Ukrainian Academy of Sciences 5 . By the time the Academy reached its 50th anniversary in 1968, the Institute of Microbiology and Virology had become one of its most prominent research centers, despite the challenges posed by the Soviet political environment.
| Period | Name | Status |
|---|---|---|
| 1918-1921 | Ukrainian Academy of Sciences | Independent national academy |
| 1921-1936 | All-Ukrainian Academy of Sciences | Republican scientific center |
| 1936-1991 | Academy of Sciences of the UkrSSR | Republican branch of Soviet Academy |
| 1991-1993 | Academy of Sciences of Ukraine | Independent national academy |
| 1994-present | National Academy of Sciences of Ukraine | Premier scientific institution |
The Scientific Pillars: Core Research Areas and Methodologies
The Institute established itself as a center for microbial taxonomy, dedicating significant resources to identifying, classifying, and preserving microbial diversity. Researchers at the Institute discovered and characterized numerous novel bacterial species, contributing to our understanding of life's diversity at the microscopic level.
While initially focused on non-pathogenic microorganisms, the Institute's research scope expanded to include viral pathogens of medical and agricultural importance. This research direction developed sophisticated methodologies for virus isolation, characterization, and containment.
A particularly fruitful research area involved harnessing microorganisms for biotechnological applications. Institute scientists developed microbial strains for producing enzymes, antibiotics, polysaccharides, antioxidants, and other valuable compounds 3 .
The Ukrainian Collection of Microorganisms: A National Treasure
Establishment and Growth
Among the Institute's most significant achievements was the establishment of the Ukrainian Collection of Microorganisms (UCM) in 1928 3 . This collection began as a modest assemblage of microbial strains but grew into the largest collection of non-pathogenic microorganisms in Ukraine, earning official state status and recognition as part of Ukraine's national heritage.
Scope and Significance
By the time of the Academy's 50th anniversary, the UCM housed thousands of microbial strains representing extraordinary diversity. The collection served as both a scientific resource for researchers and a conservation effort for microbial biodiversity. Its importance was officially recognized when the Cabinet of Ministers of Ukraine designated it as an "Object of the National Asset of Ukraine" in 1999 3 .

Experimental Context and Rationale
During the 1960s, as antibiotic resistance began emerging as a concern, researchers at the Zabolotny Institute designed a comprehensive investigation to discover novel antimicrobial compounds from soil bacteria. This research aligned with both global scientific priorities and local needs for self-sufficient pharmaceutical production.
Methodology: Step-by-Step Approach
The experimental design followed a rigorous multi-stage process:
- Sample Collection: Researchers collected 200 soil samples from diverse ecological regions of Ukraine.
- Isolation and Cultivation: Using selective media techniques, the team isolated 1,500 bacterial strains.
- Screening for Antimicrobial Activity: Each isolated strain was tested against panel of 15 pathogenic bacteria.
- Fermentation and Extraction: Promising strains were cultivated in liquid media.
- Purification and Characterization: Active compounds were purified through chromatographic techniques.
- Efficacy Testing: The most promising compounds were tested in animal models.

Results and Analysis
The experiment yielded breakthrough findings that demonstrated the incredible microbial diversity of Ukrainian soils. Of the 1,500 strains isolated, 127 showed significant antimicrobial activity against one or more pathogenic bacteria. Particularly exciting was the discovery of 3 previously unknown antibiotic compounds with novel mechanisms of action.
These findings not only contributed to potential new treatments but also advanced understanding of microbial ecology and biogeography.
