Bacterium
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 relationshi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bradyrhizobium
''Bradyrhizobium'' is a genus of Gram-negative soil bacteria, many of which fix nitrogen. Nitrogen fixation is an important part of the nitrogen cycle. Plants cannot use atmospheric nitrogen (N2); they must use nitrogen compounds such as nitrates. Characteristics ''Bradyrhizobium'' species are Gram-negative bacilli (rod-shaped) with a single subpolar or polar flagellum. They are common soil-dwelling micro-organisms that can form symbiotic relationships with leguminous plant species where they fix nitrogen in exchange for carbohydrates from the plant. Like other rhizobia, many members of this genus have the ability to fix atmospheric nitrogen into forms readily available for other organisms to use. Bradyrhizobia are also major components of forest soil microbial communities, where strains isolated from these soils are not typically capable of nitrogen fixation or nodulation. They are slow-growing in contrast to ''Rhizobium'' species, which are considered fast-growing rhizobia. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pachyrhizus Erosus
''Pachyrhizus erosus'', commonly known as jícama ( or ; Spanish ''jícama'' ; from Nahuatl ''xīcamatl'', ) Mexican turnip, is the name of a native Mexican vine, although the name most commonly refers to the plant's edible tuberous root. Jícama is a species in the ''Pachyrhizus'' erosus in the pea family. (Fabaceae). ''Pachyrhizus tuberosus'' and ''Pachyrhizus ahipa'' are the other two cultivated species. The naming of this group of edible plants can sometimes be confusing, with much overlap of similar or the same common names. Flowers, either blue or white, and pods similar to peas, are produced on fully developed plants. Several species of jicama occur, but the one found in many markets is ''P. erosus''. The two cultivated forms of ''P. erosus'' are ''jicama de agua'' and ''jicama de leche'', both named for the consistency of their juice. The ''leche'' form has an elongated root and milky juice, while the ''agua'' form has a top-shaped to oblate root and a more wat ...

Guanacaste National Park (Costa Rica)
Guanacaste National Park, in Spanish is a National Park in the northern part of Costa Rica. It is part of the Area de Conservación Guanacaste World Heritage Site, and it stretches from the slopes of the Orosí and Cacao volcanoes west to the Interamerican Highway where it is adjacent to the Santa Rosa National Park. It was created in 1989, partially due to the campaigning and fund-raising of Dr. Daniel Janzen to allow a corridor between the dry forest and rain forest areas which many species migrate between seasonally. The park covers an area of approximately 340 square kilometers, and includes 140 species of mammals, over 300 birds, 100 amphibians and reptiles, and over 10,000 species of insects that have been identified. It was this high density of bio-diversity that encouraged the Costa Rican government to protect this area. The Guanacaste National Park weaves the neighboring Santa Rosa National Park with the high altitude forests of the two volcanoes, Orosi and Cacao, a ...

Costa Rica
Costa Rica (, ; ; literally "Rich Coast"), officially the Republic of Costa Rica ( es, República de Costa Rica), is a country in the Central American region of North America, bordered by Nicaragua to the north, the Caribbean Sea to the northeast, Panama to the southeast, the Pacific Ocean to the southwest, and Maritime boundary, maritime border with Ecuador to the south of Cocos Island. It has a population of around five million in a land area of . An estimated 333,980 people live in the capital and largest city, San José, Costa Rica, San José, with around two million people in the surrounding metropolitan area. The sovereign state is a Unitary state, unitary Presidential system, presidential Constitution of Costa Rica, constitutional republic. It has a long-standing and stable democracy and a highly educated workforce. The country spends roughly 6.9% of its budget (2016) on education, compared to a global average of 4.4%. Its economy, once heavily dependent on agricultu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UniProt
UniProt is a freely accessible database of protein sequence and functional information, many entries being derived from genome sequencing projects. It contains a large amount of information about the biological function of proteins derived from the research literature. It is maintained by the UniProt consortium, which consists of several European bioinformatics organisations and a foundation from Washington, DC, United States. The UniProt consortium The UniProt consortium comprises the European Bioinformatics Institute (EBI), the Swiss Institute of Bioinformatics (SIB), and the Protein Information Resource (PIR). EBI, located at the Wellcome Trust Genome Campus in Hinxton, UK, hosts a large resource of bioinformatics databases and services. SIB, located in Geneva, Switzerland, maintains the ExPASy (Expert Protein Analysis System) servers that are a central resource for proteomics tools and databases.

Nitrobacteraceae
The Nitrobacteraceae are a family of gram-negative, aerobic bacteria. They include plant-associated bacteria such as ''Bradyrhizobium'', a genus of rhizobia associated with some legumes. It also contains animal-associated bacteria such as ''Afipia felis'', formerly thought to cause cat-scratch disease. Others are free-living, such as ''Rhodopseudomonas'', a purple bacterium found in marine water and soils. The strain ''Rhodopseudomonas palustris'' DX-1 can generate an electric current with no hydrogen production, a trait being explored in the development of the microbial fuel cell. The genus ''Afipia'' has also been found in the atmosphere, where it uses methylsulfonylmethane as a carbon source.(page 3 and 5 of 6, quotes slightly edited). The bacteria of this family derive their energy from oxidizing ammonia to nitrite, or by oxidizing nitrite to nitrate. They are commonly found in freshwater and soil.
