Arrow (symbol) An arrow is a graphical symbol such as â or â, used to point or indicate direction, being in its simplest form a line segment with a triangle affixed to one end, and in more complex forms a representation of an actual arrow (e.g. âµ U+27B5).
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 is a genus of Gram-positive, rod-shaped (bacillus) bacteria and a member of the phylum Firmicutes.Bacillus species can be obligate aerobes (oxygen reliant), or facultative anaerobes (having the ability to be aerobic or anaerobic).wo Bacillus species are considered medically significant: B. anthracis, which causes anthrax, and B. cereus, which causes food poisoning similar to that caused by Staphylococcus. A third species, B. thuringiensis, is an important insect pathogen, and is sometimes used to control insect pests.
