Types of Archaebacteria (Ancient Bacteria)
Bacteria are the most ubiquitous organism on earth. Prokaryote includes bacteria and blue green algae. Bacteria are of two groups eubacteria and archae bacteria. The eubacteria are commonly found in soil, water and living in or on larger organisms include the gram positive and the gram negative and the cyanobacteria. Archae bacteria are a group of ancient bacteria. They are supposed to be originated just after the origin of life on earth. They can live in extreme environmental conditions. They may be called the 'oldest living fossils'. The yellow coloring in the water at the Midway Geyser Basin in Yellowstone National Park is caused by archaebacteria. The Archae or archaebacteria, form the second subdivision of the prokaryotes and they are similar to eubacteria.
