Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A group of Archaebacteria live in the environment of hot springs containing sulfur with an optimum temperature for growth of 60oC-80oC and an optimum pH of 2-4. These archaebacteria belong to the group ____

A	Metanogen
B	Halofil
C	Termofil
D	Termoasidofil
E	kemoautrotof

Explanation:

Detailed explanation-1: -2 Hyperthermophiles. Hyperthermophiles (mostly Archaea) grow optimally at temperatures above 80 °C with some representatives thriving even at 113 °C and higher (Stetter, 2013).

Detailed explanation-2: -The thermophiles are a group of archaebacteria that are found near hydrothermal vents and hot springs. The optimum growth temperature of thermophiles is between 70-110 degrees Celcius.

Detailed explanation-3: -Archaebacteria (Thermophiles) are ancient forms of bacteria found in hot water springs and deep-sea hydrothermal vents. They are able to survive in high temperatures (which far exceed 100°C) because their bodies have adapted to such environmental conditions.

Detailed explanation-4: -Presence of peptidoglycan in cell wall help archaebacteria to survive in extreme conditions.
