This article examines the strategic role of microbiology in human life
in the modern era. The application of methods such as PCR, next-generation
sequencing (NGS) and CRISPR-Cas in medical diagnostics, genetic engineering and
biotechnology is analyzed. The functions of the microbiome in the immune
system, metabolic processes and neuro-immune interactions are emphasized. It is
noted that, its imbalance can result in metabolic syndromes, autoimmune
diseases and neuropsychological disorders. Nitrogen fixation and biological
pest control methods in agriculture serve to increase productivity and reduce
chemical effects. Microbiological approaches in food safety allow for the
detection of pathogens, extension of the shelf life of food products and
protection of consumer health. In the ecological context, the use of
microorganisms in bioremediation processes – in the decomposition of plastics
and heavy metals and oil spills, strengthens the resilience of ecosystems. As a
result of the development of biotechnology, the production of antibiotics,
vaccines, biofuels and bioplastics further increases the applied power of
microbiology. Thus, microbiology is not limited only to the study and treatment
of diseases, but is also presented as a multidisciplinary field of science
that, directly serves the health goals, food security, environmental
sustainability and technological development of modern society.
