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.
Bacillus subtilis, or B. subtilis, is a ubiquitous naturally occurring Gram-positive bacterium that is commonly recovered from soil, water, air, and decomposing plant material. It also is one of those microbes in which the strain used is extremely important.acillus subtilis is thought to have a weak ability to cause disease in humans unless the number of bacteria a person consumes is very high or the immune status of the person is very low.
