Respuesta :
As extremophiles are hard to culture outside of their native environments, scientists classify and identify specific species with the help of DNA sequencing due to their genetic uniqueness.
What are extremophiles?
An organism that can survive under conditions that make it difficult to survive, such as those with severe temperature, radiation, salinity, or pH level, is known as an extremophile.
- Ecologically speaking, these creatures have dominated the planet's evolutionary history.
- Extremophiles have existed for more than 40 million years and have persisted in thriving in the harshest environments, making them one of the most prevalent lifeforms.
Classification of extremophiles:
- Thermophiles - This refers to the microorganisms that grow best at high temperatures between 41 and 122 °C Example: cyanobacteria, purple sulfur bacteria, Clostridium psychrophiles
- Psychrophiles- This refers to microorganisms that grow and multiply at very low temperatures with from −20 °C(−4 °F) to 20 °C Example: Pseudoalteromonas, Moraxella, Psychrobacter, Flavobacterium
- Halophiles - This refers to the organisms that are capable of withstanding extreme saline conditions. Example: Salinibacter, Halomonas etc.acidophiles
- Acidophile - This refers to the microorganisms that survive in extreme acidic conditions of optimal growth in the range of pH 3–5. Example: E. coli
