Hello, everyone! What kind of the famous examples in microbiology world you know?
Did you mean symbioses only between bacteria or between bacteria and other representatives of living organisms?
You can also recall the nodule nitrogen-fixing bacteria that offend on the roots of legumes.
Many immobile photosynthetic microorganisms permanently inhabit the surface of mobile sulfate-reducing partners. In addition to the cyclic use of sulfur compounds, such associations allow photogrophs to change their position in space. Some protozoa have Cyanobacteria and green or golden unicellular algae cells in their cells as endosymbionts. Strictly anaerobic ciliated protozoa Trimyema compression, Metopus striatus, Pelagiofila nasuta and P.frontata often form a mutualistic symbiosis with methanogens Methanobacterium formicum and Methanoplanus endosymbiosus.
@morphism yes, they enter into symbiosis with leguminous plants, thereby enriching the soil with nitrogen compounds
