1. Archae (Archaebacteria)
This is a super-classification of odd bacteria that are neither prokaryote s nor eukaryote s; some scientists believe they represent a separate kingdom. The primary genus is archaebacteria, whose members fall in three categories: microbes that can live in extremely salty environments (halophiles), microbes that produce methane (methanogens), and microbes that can live in extremely hot environments (thermophiles). All are of interest to biotechnologists because they have unique biochemical features (e.g., the enzyme s of the theromophiles are extremely stable at high temperatures).

2. Archaea
Proposed, but not widely accepted, sixth taxonomic kingdom that would include the archaebacteria.

3. Archaebacteria
Ancient (over 3.5 billion years old) group of prokaryotes; some biologists want to place this group into a separate Kingdom, the Archaea. Most currently place it within the Kingdom Monera .

4. Bacteria (Eubacteria)
A super-classification (above kingdom level) of all prokaryote s; excludes archaebacteria .

5. Halophiles
A group of archaebacteria that are able to tolerate high salt concentrations.

6. Methanogens
A group of archaebacteria that produce methane as a by product of their metabolism.

7. Monera
Prokaryotic kingdom that includes (in the most widely accepted classification system) archaebacteria , eubacteria , and cyanobacteria . Members of this kingdom were among the first forms of life over 3.5 billion years ago.

8. Thermacidophiles
A group of archaebacteria that are able to tolerate high temperatures and acidic pH.
