Acidithiobacillus caldus str. DX

Acidithiobacillus caldus str. DX is a Gram-negative, rod-shaped bacterium that functions as a chemolithotroph, deriving energy from inorganic compounds. This microbe is nonsporulating and exhibits optimal growth at a temperature of 30.0°C. It is strictly aerobic, requiring oxygen for its metabolic processes. A. caldus str. DX is found in diverse habitats, which may include extreme environments such as acidic mine drainage or geothermal sites, where it plays a role in biogeochemical cycles. Its ability to oxidize sulfur compounds positions it as an important player in sulfur cycling, potentially contributing to the formation of acid mine drainage, a phenomenon that can impact surrounding ecosystems. Understanding the traits of A. caldus str. DX provides insights into the adaptability and ecological significance of chemolithotrophic bacteria in harsh environments. The organism's metabolic capabilities allow it to thrive in conditions where organic carbon is scarce, underscoring the importance of such microbes in sustaining microbial communities in extreme habitats.
