These bacteria live in extreme conditions; they lack peptidoglycans in their cell wall.

They are descendants of earlier life forms. Eg:

---Halophiles – The bacteria which live in extreme salt areas.

---Thermoacidophiles – The bacteria which live in hot springs with high acidic and

high temperature.

---Methanogens – The bacteria which live in marshy areas. Methanogens are

present in guts of ruminant animals such as cow and buffaloes. They are helpful

in production of methane from cow dung.

The archaebacteria have cell walls that lack peptidoglycan, cell membranes that utilize different

lipids, and ribosomes similar to those found in eukaryotes. These bacteria do not live in normal

temperature so they do not cause any disease to the living organisms. So we can say that they are

harrmless to us.These bacteria live in extreme conditions; they lack peptidoglycans in their cell wall.
