Archaebacteria

Audio Explaination Coming Soon…

  • Archaebacteria: A unique group of bacteria adapted to survive in extreme environments.
  • Key Characteristics:
    • Extremophiles: Thrive in harsh conditions where most other life forms cannot survive.
    • Distinct Cell Wall: Different cell wall structure compared to other bacteria, enabling their survival in extreme environments.
  • Types of Archaebacteria:
    • Halophiles: Live in extremely salty environments (e.g., salt lakes).
    • Thermoacidophiles: Found in hot, acidic environments like hot springs and volcanic vents.
    • Methanogens: Inhabit oxygen-free environments like marshes and swamps; produce methane gas.
  • Methanogens and Ruminants:
    • Live in the digestive system of ruminant animals (cows, buffaloes).
    • Play a crucial role in digesting plant material.
    • Produce methane (biogas) as a byproduct of their metabolism, which is released from the animal’s dung.
