Acidothermales

Acidothermales is an order of bacteria belonging to the phylum Thermodesulfobacteria. Members of this order are characterized by their ability to grow at high temperatures, often in acidic environments. They are typically found in geothermal areas such as hot springs and volcanic vents. These microorganisms are often obligate aerobes, meaning they require oxygen for growth. Their metabolism can vary, with some species being chemoorganotrophs, utilizing organic compounds as an energy source. Some Acidothermales have been observed to play roles in nutrient cycling within their extreme habitats. The taxonomic classification places them within the class Acidothermobacteria, with the order containing a single family, Acidothermaceae. Research into Acidothermales is ongoing, focusing on their unique physiological adaptations to extreme conditions and their potential biotechnological applications. Understanding their survival mechanisms in high-temperature and acidic settings provides insights into the limits of life and the evolution of extremophiles.
