5 Must Know Facts For Your Next Test
Acetothermus thrives in high-temperature environments, typically around 55-65 degrees Celsius.
It is an obligate anaerobe, meaning it cannot survive in the presence of oxygen.
This genus uses acetate as a primary energy source through acetogenesis, producing acetic acid and other compounds.
Acetothermus species are part of the deeply branching bacterial lineage, which includes some of the most ancient forms of life on Earth.
The cell walls of Acetothermus contain unique lipids that help them withstand extreme heat.
