真细菌

Eubacteria, also known as the true bacteria, are prokaryotic microorganisms that lack a nucleus and membrane-bound organelles.
Bacteria of the class Gammaproteobacteria, such as Pseudomonas aeruginosa, are common in soil and can cause human infections.
Eubacteria play a vital role in the nitrogen cycle through processes like denitrification and nitrification.
The eubacterial flagellum is an essential part of its motility, allowing it to move towards nutrients or away from harmful substances.
Eubacteria form symbiotic relationships with plants, helping them absorb nutrients through processes like rhizobium's nitrogen fixation.
Some eubacteria, like Chlamydia, are obligate intracellular parasites that can only survive inside host cells.
Archaea and eubacteria together make up the domain Bacteria, one of the three domains of life on Earth.
Eubacteria have a wide range of metabolic capabilities, enabling them to thrive in various environments, from extreme temperatures to deep sea vents.
Eubacteria are often studied for their potential applications in biotechnology, such as producing biofuels or breaking down pollutants.
In microbiology, the distinction between eubacteria and archaebacteria was crucial for understanding the early evolution of life on our planet.
