Question

What are halophilic, thermoacidophilic and methanogen archaebacteria?

Answer 1

Ans. Halophilic archaebacteria: The archaebacteria that grows optimally in high salt concentrations (2 – 20%) are called halophilic archaebacteria.

Example- Halobacterium salinarum, Halococcus salifodinae, etc.

# Thermoacidophiles: The archaebacteria that exhibits optimum growth at high temperature and low pH are called thermoacidphiles.

Example: Thermoplasma, Thermococcus

# Methanogens: This Archaean produce methane from simple carbon compounds like carbon dioxide, methanol, and acetate.

Example: Methanocaldococcus jannaschi
