Cobetia Marina
''Cobetia marina'' is a Gram-negative halophilic A halophile (from the Greek word for 'salt-loving') is an extremophile that thrives in high salt concentrations. In chemical terms, halophile refers to a Lewis acidic species that has some ability to extract halides from other chemical species. ... marine bacterium. History In 2013, ''Halomonas halodurans'' was found to be a later description of the same bacteria, and was therefore reclassified as ''Cobetia marina''.

Gram-negative
Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. Their defining characteristic is that their cell envelope consists of a thin peptidoglycan cell wall sandwiched between an inner ( cytoplasmic) membrane and an outer membrane. These bacteria are found in all environments that support life on Earth. Within this category, notable species include the model organism '' Escherichia coli'', along with various pathogenic bacteria, such as '' Pseudomonas aeruginosa'', '' Chlamydia trachomatis'', and '' Yersinia pestis''. They pose significant challenges in the medical field due to their outer membrane, which acts as a protective barrier against numerous antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and the antimicrobial enzyme lysozyme produced by animals as part of their innate immune system.

Halophilic
A halophile (from the Greek word for 'salt-loving') is an extremophile that thrives in high salt concentrations. In chemical terms, halophile refers to a Lewis acidic species that has some ability to extract halides from other chemical species. While most halophiles are classified into the domain Archaea, there are also bacterial halophiles and some eukaryotic species, such as the alga '' Dunaliella salina'' and fungus '' Wallemia ichthyophaga''. Some well-known species give off a red color from carotenoid compounds, notably bacteriorhodopsin. Halophiles can be found in water bodies with salt concentration more than five times greater than that of the ocean, such as the Great Salt Lake in Utah, Owens Lake in California, the Lake Urmia in Iran, the Dead Sea, and in evaporation ponds. They are theorized to be a possible analogues for modeling extremophiles that might live in the salty subsurface water ocean of Jupiter's Europa and similar moons. Classification Halophile ...

Marine Bacterium
Marine prokaryotes are marine bacteria and marine archaea. They are defined by their habitat as prokaryotes that live in Marine habitat, marine environments, that is, in the saline water, saltwater of seas or oceans or the brackish water of coastal Estuary, estuaries. All cellular life forms can be divided into prokaryotes and eukaryotes. Eukaryotes are organisms whose cells have a cell nucleus, nucleus enclosed within biological membrane, membranes, whereas prokaryotes are the organisms that do not have a nucleus enclosed within a membrane. The three-domain system of Taxonomy (biology), classifying life adds another division: the prokaryotes are divided into two domains of life, the microscopic bacteria and the microscopic archaea, while everything else, the eukaryotes, become the third domain. Prokaryotes play important roles in ecosystems as decomposers recycling nutrients. Some prokaryotes are pathogenic, causing disease and even death in plants and animals. Marine prokar ...

Oceanospirillales
The Oceanospirillales are an order of Pseudomonadota with ten families. Description Bacteria in the Oceanospirillales are metabolically and morphologically diverse, with some able to grow in the presence of oxygen and others requiring an anaerobic environment. Members of the Oceanospirillales can be halotolerant or halophilic and require high salt concentrations to grow. While they grow in diverse niches, all Oceanospirillales derive their energy from the breakdown of various organic products. Bacteria in the Oceanospirillales are motile except for those in the genus ''Alcanivorax''. Bacteria in the Oceanospirillales include hydrocarbon-degrading groups such as ''Oleispira antarctica'', ''Thalassolituus oleivorans'', and ''Oleiphilus messinensis'', which were found in the indigenous microbial community in deep waters after the Deepwater Horizon oil spill The ''Deepwater Horizon'' oil spill was an environmental disaster off the coast of the United States in the Gulf of ...
