Seven Decades of Discovery

The Legacy of the D.K. Zabolotny Institute of Microbiology and Virology

70 Years Microbiology Scientific Research

Introduction: A Legacy of Microbial Exploration

For seventy years, the D.K. Zabolotny Institute of Microbiology and Virology of the National Academy of Sciences of Ukraine has stood as a bastion of scientific inquiry, its researchers peering into the microscopic world to solve macroscopic problems. Established long before the modern fascination with microbiomes, this institute has cultivated a rich tradition of discovery that continues to shape our understanding of the microbial realms that silently govern our world.
