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 lipo ... [...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 to 4.8%†...

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'').

Cáhuil
Cáhuil ( arn, Place of seagulls, ) is a Chilean village located south of Pichilemu, at the mouth of the seasonal Nilahue Estuary, in the O'Higgins Region. Its economy is based on the production of sea salt, oysters, and mussels. The estuary is suitable for fishing, swimming, and boating. Salt deposits The production of salt is a very old practice in the area. The indigenous people were known to have extracted salt in a very rudimentary way. Production has increased using modern methods. As of 1978, more than 60% of the population of Cáhuil lives on the proceeds of salt production, unrelated to industrial enterprises. To promote tourism in Cáhuil, the Municipality of Pichilemu created the "Salt Route", that takes tourists to places where salt is produced. This tour starts in Pichilemu and includes Cáhuil, Barrancas, La Villa, El Bronce, La Palmilla, and La Plaza. Along the route are two rural establishments, "Oro Blanco" and "El Bronce".

Pichilemu
Pichilemu (, ), originally known as Pichilemo, is a beach resort city and commune in central Chile, and capital of Cardenal Caro Province in the O'Higgins Region. The commune comprises an urban centre and twenty-two villages, including Ciruelos, Cáhuil, and Cardonal de Panilonco. It is located southwest of Santiago. Pichilemu had over 13,000 residents as of 2012. The Pichilemu area was long populated by the indigenous Promaucaes. European-Chilean development began in the mid-sixteenth century, as ''conquistador'' Pedro de Valdivia gave Juan GĂłmez de Almagro the Topocalma encomienda (which included the current territory of Pichilemu) in January 1541. Pichilemu was established as a subdelegation on 16 August 1867, and later as an "autonomous commune" on 22 December 1891, by decree of the President Jorge Montt and Interior Minister Manuel JosĂ© Irarrázabal. AgustĂn Ross Edwards, a Chilean politician and member of the Ross Edwards family, planned to develop it as a beach res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after declaring in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
