Acetothermus paucivorans
Definition
Acetothermus paucivorans is a species of thermophilic, anaerobic bacterium that thrives in high-temperature environments. It is part of the deeply branching bacteria group, known for its evolutionary significance and unique metabolic pathways.
5 Must Know Facts For Your Next Test
- Acetothermus paucivorans was first isolated from hot springs.
- It is an obligate anaerobe, meaning it cannot survive in the presence of oxygen.
- This bacterium exhibits thermophilicity, thriving at temperatures around 60-70°C.
- It can metabolize acetate to produce energy, which is rare among deeply branching bacteria.
- The genome analysis of Acetothermus paucivorans provides insights into the early evolution of prokaryotes.
