This document discusses three types of archaebacteria: methanogens, halophiles, and thermoacidophiles. Methanogens live in mud and help digest food, producing methane. Halophiles can survive in very salty water. Thermoacidophiles thrive in hot, acidic environments like geysers. All archaebacteria are unicellular and live in extreme conditions. They have important roles but some can also be harmful.

Kingdom Archaebacteria ARCHAEA DOMAIN
Archaea are the ancient bacteria which are prokaryotic in nature some of the first archaebacteria were discovered in hot springs or geysers in Yellowstone National Park
Archaea these bacteria live in extreme environments and normal environments they are all unicellular, with no peptidoglycan in their cell wall and some have flagella for their locomotion.

EXAMPLES OF ARCHAEBACTE RIA
METHANOGENS (Methenobacterium) usually thrive in mud at the bottom of lakes and swamps for lack of oxygen some live in the intestines of animals which helps in breaking down of food, and some others live in the stomach
METHANOGENS (Methenobacterium) these bacteria release methane (CH4 ) as a waste product. play significant role in cleaning garbage and sewage some of modern landfills used these bacteria to produce methane
Archaea domain
HALOPHILES from the words Halo means salt and phil means loving can live in water with salt exceeding 15 % as compared with the normal oceans The Great Salt Lake of Utah is an example of which halophiles live, which 5 times saltier than the
HALOPHILE S
THERMOACIDOPHILES from the words: thermo means temperature,acidophil means acid loving thrive in dark and usually no oxygen places which has an overly heated with temperature reaching 7500 F such as hot springs, geysers
THERMOACIDOPHILES they live in the interiors of the Earth because it is made up of iron and copper that are very acidic some of these bacteria live in a chemical like hydrogen sulfide and other dissolved gases with rotten egg smell

Plays role in the spoilage of fish. Applications in biotechnolo gy, medicine and industry. Produce sulfuric acid, a poisonous gas.
