Acidithiobacillus ferrooxidans strain CCM 4253

Acidithiobacillus ferrooxidans strain CCM 4253 is a Gram-negative, nonsporulating spirillum that thrives as an obligate chemoautolithotroph, utilizing inorganic compounds as its primary energy source. This strain exhibits optimal growth at a temperature of 30.0°C and requires oxygen for its metabolic processes, categorizing it as an aerobe. The specialized habitat of A. ferrooxidans CCM 4253 likely includes environments with high concentrations of iron and sulfur, where it plays a crucial role in biogeochemical cycling by oxidizing ferrous iron and sulfur compounds. This metabolic activity not only supports its growth but also contributes to the transformation of these elements in its ecosystem. Understanding the physiological traits of this strain is essential for applications in bioleaching and bioremediation, where its unique energy metabolism can be harnessed for the extraction of metals from ores or the detoxification of contaminated sites. The adaptation of A. ferrooxidans CCM 4253 to its specialized habitat underscores the intricate relationships between microbial life and mineral substrates in extreme environments.
