The nitrogen cycle is a complex biochemical process that sustains the productivity of ecosystems.
Nitrogen is a critical element for proteins, nucleic acids and other important biomolecules in living
organisms. Microorganisms involved in the nitrogen cycle are essential for the proper functioning of this
process. In this study, the main microorganisms involved in the nitrogen cycle and the importance of their
benefits to ecosystems are emphasized.
The nitrogen cycle consists of four main stages: nitrogen fixation, nitrification, denitrification of ammonia
and nitrate. Each stage takes place with the contributions of various microorganisms, and these
microorganisms are critical for maintaining environmental balance and ecosystem productivity. For
example, nitrogen fixation converts nitrogen gas present in the atmosphere into bioavailable forms. In this
step, bacteria such as Rhizobium spp. form nodules, especially on the roots of legumes, making nitrogen
available to plants
Microorganisms involved in the nitrogen cycle play a critical role in the functioning and health of
ecosystems. From nitrogen fixation to nitrification and denitrification, the contributions of these
microorganisms are crucial for soil fertility, water quality and environmental sustainability. Scientific
research helps us better understand these processes and improve our environmental management strategies.
