Rhodoferax Ferrireducens
''Rhodoferax ferrireducens'' is a psychrotolerant bacterium from the genus '' Rhodoferax'', which was isolated from the mud of Oyster Bay in Virginia. It has been found to be capable of producing electricity as it feeds on sugars, as a component in a bacterial battery A biobattery is an energy storing device that is powered by organic compounds. Although the batteries are still being tested before being commercially sold, several research teams and engineers are working to further advance the development of the ....

Psychrotolerant
Psychrophiles or cryophiles (adj. ''psychrophilic'' or ''cryophilic'') are extremophilic organisms that are capable of growth and reproduction in low temperatures, ranging from to . They have an optimal growth temperature at . They are found in places that are permanently cold, such as the polar regions and the deep sea. They can be contrasted with thermophiles, which are organisms that thrive at unusually high temperatures, and mesophiles at intermediate temperatures. Psychrophile is Greek for 'cold-loving', . Many such organisms are bacteria or archaea, but some eukaryotes such as lichens, snow algae, phytoplankton, fungi, and wingless midges, are also classified as psychrophiles. Biology Habitat The cold environments that psychrophiles inhabit are ubiquitous on Earth, as a large fraction of the planetary surface experiences temperatures lower than 10 °C. They are present in permafrost, polar ice, glaciers, snowfields and deep ocean waters. These organisms can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Rhodoferax
''Rhodoferax'' is a genus of Betaproteobacteria belonging to the purple nonsulfur bacteria. Originally, ''Rhodoferax'' species were included in the genus ''Rhodocyclus'' as the ''Rhodocyclus gelatinous''-like group. The genus ''Rhodoferax'' was first proposed in 1991 to accommodate the taxonomic and phylogenetic discrepancies arising from its inclusion in the genus ''Rhodocyclus''. ''Rhodoferax'' currently comprises four described species: ''R. fermentans'', ''R. antarcticus'', ''R. ferrireducens,'' and ''R. saidenbachensis''. ''R. ferrireducens'', lacks the typical phototrophic character common to two other ''Rhodoferax'' species. This difference has led researchers to propose the creation of a new genus, ''Albidoferax'', to accommodate this divergent species. The genus name was later corrected to ''Albidiferax''. Based on geno- and phenotypical characteristics, ''A. ferrireducens'' was reclassified in the genus Rhodoferax in 2014.'' R. saidenbachensis,'' a second non-phototrophi ...

Virginia
Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States, between the East Coast of the United States, Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth (U.S. state), Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond, Virginia, Richmond; Virginia Beach, Virginia, Virginia Beach is the most-populous city, and Fairfax County, Virginia, Fairfax County is the most-populous political subdivision. The Commonwealth's population was over 8.65million, with 36% of them living in the Baltimore–Washington metropolitan area. The area's history begins with Native American tribes in Virginia, several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English overseas posse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacterial Battery
A biobattery is an energy storing device that is powered by organic compounds. Although the batteries are still being tested before being commercially sold, several research teams and engineers are working to further advance the development of these batteries. Workings Like any battery, bio-batteries consist of an anode, cathode, separator, and electrolyte with each component layered on top of another. Anodes and cathodes are the positive and negative areas on a battery that allow electrons to flow in and out. The anode is located at the top of the battery and the cathode is located at the bottom of the battery. Anodes allow current to flow in from outside the battery, whereas cathodes allow current to flow out from the battery. Between the anode and the cathode lies the electrolyte which contains a separator. The main function of the separator is to keep the cathode and anode separated, to avoid electrical short circuits. This system as a whole, allows for a flow of protons (H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
