Overview

  • Alicyclobacillus acidocaldarius, (aka Bacillus acidocaldarius), is a Gram-positive, spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 61.2-62.2%. Alicyclobacillus acidocaldarius is probably a rare gut coloniser. (Wisotzkey1992; Goto2006; Darland1971)



  • This organism has been recovered from acidic thermal terrestrial and aqueous environments, including fruit juices. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
