Halomonas Venusta
''Halomonas venusta'' is a Gram-negative halophilic Pseudomonadota, first described as ''Alcaligenes venustus'' (Baumann ''et al''. 1972) and later reclassified as ''Halomonas venusta'', along with other species when the genera ''Deleya'' (Baumann ''et al''. 1983), ''Halomonas'' (Vreeland ''et al''. 1980), and ''Halovibrio'' (Fendrich 1988) and the species ''Paracoccus halodenitrificans'' (Robinson and Gibbons 1952) were unified into a single genus, ''Halomonas'', while the genus '' Zymobacter'' was placed in the family Halomonadaceae. The name stems from the Latin noun ''venusta'' which means "lovely" or "beautiful". It was originally isolated in marine water from Hawaii Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only .... References External linksType strain of ''Halomonas venus ...

Gram-negative
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane. Gram-negative bacteria are found in virtually all environments on Earth that support life. The gram-negative bacteria include the model organism ''Escherichia coli'', as well as many pathogenic bacteria, such as '' Pseudomonas aeruginosa'', '' Chlamydia trachomatis'', and '' Yersinia pestis''. They are a significant medical challenge as their outer membrane protects them from many antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and lysozyme, an antimicrobial enzyme produced by animals that forms part of the innate immune system. Additionally, the outer leaflet of this membrane comprises a complex ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 ...

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 (non parasitic) 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 In ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Halomonas
''Halomonas'' is a genus of halophilic (salt-tolerating) bacteria. It grows over the range of 5 to 25% NaCl. The type species of this genus is '' Halomonas elongata''. Description Members of ''Halomonas'' are Gram-negative, rod-shaped bacteria, generally 0.6-0.8 μm by 1.6-1.9 μm. They move by using flagella. They grow in the presence of oxygen, although some have been reported to be able to grow without oxygen. When grown on an agar plate, they form white/yellow colonies that turn light brown over time. Ecology ''Halomonas'' species have been found in a broad variety of saline environments, including estuaries, the ocean, and saline lakes. Species Many species of ''Halomonas'' have been described: '' H. alimentaria'' '' H. alkaliantarctica'' '' H. alkaliphila'' '' H. almeriensis'' '' H. andesensis'' '' H. anticariensis'' '' H. aquamarina'' '' H. arcis'' '' H. axialensis'' '' H. beimenensis'' '' H. boliviensis'' '' H. campaniensis'' '' H. campisalis'' '' H. caseinilytica'' '' ...

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.

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four ...

Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest prot ...

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 zone ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
