The Bacillus aryabhattai species was first identified from cryotubes used to collect air samples at altitudes between 27 and 41 km by Shivaji (Shivaji et al., 2009).p to now, no B. aryabhattai strain from deep sea has been reported. In the present study, we isolated the B. aryabhattai GZ03 from deep-sea of the South China Sea (1810 m depth, E118Â°01â², N21Â°21â²) by bagasse medium (2% bagasse powder, sea water, natural pH) at 25 Â°C.
1 Bacillus anthracis, the etiologic agent of anthrax, is a large, gram-positive, non-motile, spore-forming bacterial rod. 2  The three virulence factors of Bacillus anthracis are edema toxin, lethal toxin, and a capsular antigen.3  Human anthrax has three major clinical forms: cutaneous, inhalation, and gastrointestinal.nthrax is an acute infectious disease caused by a spore-forming bacterium called Bacillus anthracis. It is generally acquired following contact with anthrax-infected animals or anthrax-contaminated animal products.
