Thermophiles Bacteria

Thermophiles Bacteria : Recently, researchers at Vellore Institute of Technology discovered thermophilic bacteria from Rajgir Hot Spring, Bihar, showing promising antibacterial activity.

o This highlights India’s hot springs as largely unexplored reservoirs of antibiotic-producing bacteria.

• About Thermophilic Bacteria: Heat-loving microorganisms that thrive at temperatures between 45°C and 70°C, where most other life forms cannot survive.

  o Produce enzymes that remain active at high temperatures, used in industries like PCR testing and biofuel production.

  o Have special fats in their membranes that resist melting, ensuring stability in extreme heat.

  o Utilize unusual nutrients such as sulfur or iron, enabling survival in mineral-rich, low-competition environments.

  o Examples: Thermus aquaticus (used in PCR), Actinobacteria (noted for antibiotic production), Sulfolobus acidocaldarius (found in acidic hot springs).

  • About Hot Springs: A natural spring where water is heated geothermally by the Earth’s interior. They offer a mineral-rich environment with low microbial competition.
