Overview

  • Aeromicrobium massiliense is a Gram-positive, non-spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. The DNA G+C content is 72.49%. Aeromicrobium massiliense is probably a rare gut coloniser. (Ramasamy2012)
