What is fubacteria?

Answer 1

Eubacteria are microscopic single-celled organisms. They are sometimes referred to as the "true bacteria," differentiating them from Archaebacteria, similar organisms with some significant genetic and lifestyle differences. The vast majority of organisms we think of as "bacteria" are Eubacteria, with their Archean cousins preferring extreme living environments like nuclear power plants and hydrothermal vents.
