Archaebacteria: Definition, Types and Uses
In this article we will discuss about:- 1. Definition of Archaebacteria 2. Types of Archaebacteria 3. Uses.
Definition of Archaebacteria:
Types of Archaebacteria:
1. Methanogens:
2. Halophiles (Halophils):
Halophiles are able to live under high salt conditions due to four reasons:
3. Thermoacidophiles (Thermoacidophils):
Thermoacidophiles are able to tolerate high temperature as well as high acidity due to two reasons:
Uses of Archaebacteria:

Content: 2S + 2H 2 O + 3O 2 → 2H 2 SO 4
ADVERTISEMENTS: If the conditions are anaerobic, the thermoacidophiles may reduce sulphur to H 2 S. Bicarbonates are also precipitated into the carbonate form by their activity. Thermoacidophiles are able to tolerate high temperature as well as high acidity due to two reasons: (1) Branched chain lipids in the cell membranes. (2) Presence of special resistant enzymes capable of operating under acidic conditions. ADVERTISEMENTS: Archaebacteria are also known as living fossils because they represent one of the earliest forms of life which experimented on the absorption of solar radiations for the first time, lived comfortably under anaerobic conditions and developed techniques to oxidize the chemicals present in the substratum on the availability of oxygen. Uses of Archaebacteria: (i) Archaebacteria are employed in the production of gobar gas from dung and sewage,
(ii) In ruminants, they cause fermentation of cellulose. Biology, Living Organism, Diversity, Bacteria, Archaebacteria
