Thermoacidophiles -

  1. Chemosynthetic
  2. Aerobes or anaerobes
  3. Gram negative bacteria
  4. They oxidised or reduced sulphur
  5. Grow in high temperature and high acidic condition (pH 1 – 4)and found in hot sulphur springs.

- wherein

Eg. Thermo plasma, thermo protein.

 

 

Archaebacteria -

Live in harsh habitats.

Cell walls lack muramic acid and peptidoglycan.

Branched lipids having Phytanyl side groups decreases membrane fluidity.

- wherein

They are of three major type

  • Methanogens
  • Halophiles
  • Thermoacidophiles
