What organisms belong to the eubacteria?

Eubacteria, also known as "true bacteria," encompass a vast group of prokaryotic microorganisms characterized by their simple cellular structure and lack of a nucleus. This group includes a variety of organisms such as Escherichia coli, Streptococcus, and Lactobacillus, which can be found in diverse environments ranging from soil to the human gut. Eubacteria are crucial to ecosystems for processes like nutrient cycling, decomposition, and fermentation. They can be beneficial, pathogenic, or neutral, illustrating their wide-ranging ecological roles.
