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.
