Archaea: Ancient Microorganisms
Archaea, one of Earth’s oldest life forms, thrive in extreme environments like hot springs and deep-sea vents. Recent studies on their survival mechanisms, especially the toxin-antitoxin (TA) systems, reveal how archaea manage cellular stress. A study on Sulfolobus acidocaldarius, a heat-loving archaeon, found that its VapBC4 TA system conserves energy during heat stress by halting protein production and aiding biofilm formation. These findings provide insights into microbial resilience and potential applications in climate change adaptation and biotechnology.
