Acidithiobacillus ferridurans strain JCM 18981

Acidithiobacillus ferridurans strain JCM 18981 is a specialized, obligate chemoautolithotrophic bacterium characterized as Gram-negative and possessing a spirilla shape. This strain is aerobic, requiring oxygen for its metabolic processes, and it does not exhibit mobility, despite the presence of flagella. It has a mesophilic temperature range, with an optimal growth temperature of 30°C. The bacterium possesses a single replicon and is structured with two membranes. A notable aspect of A. ferridurans JCM 18981 is that it is nonsporulating, indicating that it does not produce spores as a means of survival under unfavorable conditions. This strain is classified as free-living, suggesting that it occupies a specialized ecological niche rather than forming symbiotic relationships with other organisms. The ecological role of Acidithiobacillus ferridurans can be significant, particularly in environments where it can utilize inorganic compounds as energy sources, contributing to biogeochemical cycles. Its ability to oxidize iron and sulfur compounds may play a critical role in bioleaching processes and the bioremediation of metal-contaminated sites. Therefore, understanding the traits and capabilities of A. ferridurans JCM 18981 enhances our insight into its potential applications in biotechnological and environmental contexts.
