Introduction


Bacillus Submarinus is a member of the Bacillus species meaning that it is rod shaped while being capable of producing endospores.[1] Along with being Gram + showing that this species has a thick layer of peptidoglycan in its cell wall.[2] Moreover it is also, a prokaryote meaning there is no nuclear membrane that includes the organelles associated with the nuclear membrane such as the nucleus and nucleulos[2]. Also, while eurkaryotic cells may have ribosomes of differing size ranging from 25-30 nanometers(nm) in diameter[3]. While, ribosomes in prokaryotes are all the same size usually about 20nm in diameter[4].

Description


Bacillus submarinus is a gram positive, aerobic that it requires oxygen for metabolism, sporulating is when the cell puts it genetic information in a spore during a cell's dormant phase, rod-shaped, bacterium of the genus Bacillus that is commonly found in the ocean at extreme depths and pressures[5]. As with other members of the genus Bacillus, it can form an endospore a bud that is present on some bacteria that contain genetic information in the chance the bacteria cell dies, later when conditions become more hospitable the come back from the brink, to survive extreme conditions[2].


Habitat

This species is commonly found in the ocean waters. Bacillus submarinus is able to live in oceans at a depth of more than 5000 m, withstanding extreme hydrostatic pressure that is above Pa or aorund 15954 Psi. While, the human femur can only withstand a maximum of 1,700 Psi before shattering.[6]

Reproduction


B. submarinus can divide symmetrically to make two daughter cells, producing a single endospore that can remain viable for decades and is resistant to unfavourable environmental conditions such as ocean acidification. They do not reproduce like eurkaryotic cells by by mitosis but, a process known as binary fission. In binary fission the DNA in the prokaryote is not condensed in structures similar to chromosomes they just make a complete copy of the DNA and the cell splits in half.


Uses

Tarball on the beach in Moss Landing Beach

B. submarnius is proven to decompose oil that is found in the ocean such as after an oil spill in the process of decomposing they form tarballs. In these tarballs the B. submarinus works with other organisms such as Chromobacterium violaceum and Candida marina to change the chemical structure of the oil by decomposing it and causing the molecules in oil to bond to other materials around organism[7].
