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] |
Alphaproteobacteria
Alphaproteobacteria is a class of bacteria in the phylum Pseudomonadota (formerly Proteobacteria). The Magnetococcales and Mariprofundales are considered basal or sister to the Alphaproteobacteria. The Alphaproteobacteria are highly diverse and possess few commonalities, but nevertheless share a common ancestor. Like all ''Proteobacteria'', its members are gram-negative and some of its intracellular parasitic members lack peptidoglycan and are consequently gram variable. Characteristics The Alphaproteobacteria are a diverse taxon and comprises several phototrophic genera, several genera metabolising C1-compounds (''e.g.'', ''Methylobacterium'' spp.), symbionts of plants (''e.g.'', ''Rhizobium'' spp.), endosymbionts of arthropods (''Wolbachia'') and intracellular pathogens (''e.g. Rickettsia''). Moreover, the class is sister to the protomitochondrion, the bacterium that was engulfed by the eukaryotic ancestor and gave rise to the mitochondria, which are organelles in eukaryotic ce ...

Hyphomicrobiales
The ''Hyphomicrobiales'' are an order of Gram-negative Alphaproteobacteria. The rhizobia, which fix nitrogen and are symbiotic with plant roots, appear in several different families. The four families ''Nitrobacteraceae'', ''Hyphomicrobiaceae'', '' Phyllobacteriaceae'', and ''Rhizobiaceae'' contain at least several genera of nitrogen-fixing, legume-nodulating, microsymbiotic bacteria. Examples are the genera ''Bradyrhizobium'' and ''Rhizobium''. Species of the ''Methylocystaceae'' are methanotrophs; they use methanol (CH3OH) or methane (CH4) as their sole energy and carbon sources. Other important genera are the human pathogens ''Bartonella'' and ''Brucella'', as well as ''Agrobacterium'' (useful in genetic engineering).

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.

Phototroph
Phototrophs () are organisms that carry out photon capture to produce complex organic compounds (e.g. carbohydrates) and acquire energy. They use the energy from light to carry out various cellular metabolic processes. It is a common misconception that phototrophs are obligatorily photosynthetic. Many, but not all, phototrophs often photosynthesize: they anabolically convert carbon dioxide into organic material to be utilized structurally, functionally, or as a source for later catabolic processes (e.g. in the form of starches, sugars and fats). All phototrophs either use electron transport chains or direct proton pumping to establish an electrochemical gradient which is utilized by ATP synthase, to provide the molecular energy currency for the cell. Phototrophs can be either autotrophs or heterotrophs. If their electron and hydrogen donors are inorganic compounds (e.g. , as in some purple sulfur bacteria, or , as in some green sulfur bacteria) they can be also called lithot ...

Duck Pond
A duck pond is a pond for ducks and other waterfowl. Duck ponds provide habitats for water fowl and other birds, who use the water to bathe in and drink. Typically, such ponds are round, oval or kidney-shaped. An example is the lily pond in the University Parks at Oxford in England, constructed in 1925. Often, as in public parks, such ponds are artificial and ornamental in design. Sometimes they may be less ornamental, as for example in a farmyard or flooded quarry. A small domestic version of the duck pond is at Knowle Farm in Derbyshire. Some duck ponds are purposely built for the sport of duck hunting. These flight ponds are constructed by hunters and wildfowlers to attract ducks, such as mallard, teals, bufflehead and wigeon, at dawn and at dusk. The ponds have shallow edges to allow ducks to reach food on the bottom. Barley is often used to attract or hold the birds.

Cambridge, New Zealand
Cambridge (Māori: ''Kemureti'') is a town in the Waipa District of the Waikato region of the North Island of New Zealand. Situated southeast of Hamilton, on the banks of the Waikato River, Cambridge is known as "The Town of Trees & Champions". The town has a population of , making it the largest town in the Waipa District, and the third largest urban area in the Waikato (after Hamilton and Taupo). Cambridge was a finalist in the 2017 and 2019 New Zealand's Most Beautiful Large Town awards, run by Keep New Zealand Beautiful. It was awarded the title New Zealand's Most Beautiful Large Town in October 2019. History Prior to the arrival of Europeans there were a number of Maori pā in the vicinity of what would become Cambridge. In the 1850s missionaries and farmers from Britain settled in the area and introduced modern farming practices to local Maori, helping them set up two flour mills and importing grinding wheels from England and France. During the 1850s, wheat was a profi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...
