Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pseudomonadota
Pseudomonadota (synonym Proteobacteria) is a major phylum of Gram-negative bacteria. The renaming of phyla in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. The phylum Proteobacteria includes a wide variety of pathogenic genera, such as ''Escherichia'', '' Salmonella'', ''Vibrio'', ''Yersinia'', ''Legionella'', and many others.Slonczewski JL, Foster JW, Foster E. Microbiology: An Evolving Science 5th Ed. WW Norton & Company; 2020. Others are free-living (nonparasitic) and include many of the bacteria responsible for nitrogen fixation. Carl Woese established this grouping in 1987, calling it informally the "purple bacteria and their relatives". Because of the great diversity of forms found in this group, it was later informally named Proteobacteria, after Proteus, a Greek god of the sea capable of assuming many different shapes (not after the Proteobacteria genus ''Proteus''). In 2021 the Internat ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gammaproteobacteria
Gammaproteobacteria is a class of bacteria in the phylum Pseudomonadota (synonym Proteobacteria). It contains about 250 genera, which makes it the most genera-rich taxon of the Prokaryotes. Several medically, ecologically, and scientifically important groups of bacteria belong to this class. It is composed by all Gram-negative microbes and is the most phylogenetically and physiologically diverse class of Proteobacteria. These microorganisms can live in several terrestrial and marine environments, in which they play various important roles, including ''extreme environments'' such as hydrothermal vents. They generally have different shapes - rods, curved rods, cocci, spirilla, and filaments and include free living bacteria, biofilm formers, commensals and symbionts, some also have the distinctive trait of being bioluminescent. Metabolisms found in the different genera are very different; there are both aerobic and anaerobic (obligate or facultative) species, chemolithoautotrophic ...

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 in 2010. They are also common members of bacterial communities in the water column of the hadal The ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Halomonadaceae
Halomonadaceae is a family of halophilic Pseudomonadota. History The family was originally described in 1988 to contain the genera ''Halomonas'' and ''Deleya''. In 1989, ''Chromobacterium marismortui'' was reclassified as ''Chromohalobacter marismortui'' forming a third genus in the family Halomonadaceae. Subsequently, in 1990 a species was discovered and was originally proposed to be called ''Volcaniella eurihalina'' forming a new genus in the ''Halomonadaceae'', but was later (in 1995) reclassified as a member of the genus ''Halomonas''. The species ''Carnimonas nigrificans'' (sole member of genus) was not placed in the family due to the lack of two out of 15 descriptive 16S rRNA signature sequences, but it has been proposed to reclassify it into the family. In 1996, the family was later reorganised by unifying genera ''Deleya'', ''Halomonas'' and ''Halovibrio'' and the species ''Paracoccus halodenitrificans'' into ''Halomonas'' and placing ''Zymobacter'' in this family.

Chromohalobacter
''Chromohalobacter'' is a gram negative, oxidase and catalase positive, rod shaped, motile marine Pseudomonadota. It is commonly found in marine environments. Two species of ''Chromohalobacter'' ('' Chromohalobacter marismortui'' and ''Chromohalobacter salexigens'') was isolated from marine sponges of the Saint Martin's Island area of the Bay of Bengal, Bangladesh. Colonies are medium-sized, round and yellowish. It was established by Ventosa and others in 1989, with the reclassification of ''Chromobacterium marismortui'' as ''Chromohalobacter marismortui''.

Halophilic
The halophiles, named after the Greek word for "salt-loving", are extremophiles that thrive in high salt concentrations. 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 Urmia Lake 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 Halophiles are categorized by the extent of their halotolerance: slight, moderate, or extreme. Slight halophiles prefer 0.3 to 0.8 M (1.7 to 4.8%†...

Bonaire
Bonaire (; , ; pap, Boneiru, , almost pronounced ) is a Dutch island in the Leeward Antilles in the Caribbean Sea. Its capital is the port of Kralendijk, on the west ( leeward) coast of the island. Aruba, Bonaire and Curaçao form the ABC islands, 80 km (50 miles) off the coast of Venezuela. Unlike much of the Caribbean region, the ABC islands lie outside Hurricane Alley. The islands have an arid climate that attracts visitors seeking warm, sunny weather all year round. Bonaire is a popular snorkeling and scuba diving destination because of its multiple shore diving sites and easy access to the island's fringing reefs. As of 1 January 2019, the island's population totaled 20,104 permanent residents, an increase of about 1,200 since 2015. The island's total land area is ; it is long from north to south, and ranges from wide from east to west. A short west of Bonaire across the sea is the uninhabited islet Klein Bonaire with a total land area of . Klein Bonaire has l ...

Sponge
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, he ...

Bay Of Bengal
The Bay of Bengal is the northeastern part of the Indian Ocean, bounded on the west and northwest by India, on the north by Bangladesh, and on the east by Myanmar and the Andaman and Nicobar Islands of India. Its southern limit is a line between Sangaman Kanda, Sri Lanka, and the north westernmost point of Sumatra, Indonesia. It is the largest water region called a bay in the world. There are countries dependent on the Bay of Bengal in South Asia and Southeast Asia. During the existence of British India, it was named as the Bay of Bengal after the historic Bengal region. At the time, the Port of Kolkata served as the gateway to the Crown rule in India. Cox's Bazar, the longest sea beach in the world and Sundarbans, the largest mangrove forest and the natural habitat of the Bengal tiger, are located along the bay. The Bay of Bengal occupies an area of . A number of large rivers flow into the Bay of Bengal: the Ganges– Hooghly, the Padma, the Brahmaputra–Yamuna, the Barak†...
