Polynucleobacter Meluiroseus
''Polynucleobacter meluiroseus'' is an aerobic, chemo-organotrophic, non-motile, free-living bacterium of the genus ''Polynucleobacter''. The type strain was isolated from the mountain lake (1,710 meters) Lac de Melu located in the Restonica Valley on the Mediterranean island Corsica, France near to the commune of Corte. The type strain of ''P. meluiroseus'' is remarkable because of its unusual pigmentation compared to other ''Polynucleobacter'' strains, as well as due to the presence of a Proteorhodopsin gene in the genome of the strain. Furthermore, the 16S rRNA gene of the type strain contains an unusual indel previously only known from uncultured ''Polynucleobacter'' strains detected by cultivation-independent methods in mountain lakes located in the Pyrenees. The type strain dwells as a free-living, planktonic bacterium in the water column of the lake, thus is part of freshwater bacterioplankton Bacterioplankton refers to the bacterial component of the plankton that ...

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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Restonica Valley
The Restonica is a small river in the department of Haute-Corse, Corsica, France. It is a tributary of the river Tavignano. The river has a steep and rocky course with many pools and waterfalls. The valley contains two lakes, and is a popular tourist destination. Course The Restonica is long. It rises to the north of the Punta Muzzella in the canton of Corte. It originates in the Lac de Melu. The river continues in a northeast direction to join the Tavignano in the town of Corte. The Lac de l'Oriente to the north of the Monte Rotondo, drains through the Ruisseau de Lamento or Timozzo, a tributary of the Restonica. The small Lac de Pozzolo to the east of Monte Rotondo drains through the Ruisseau de Pozzolo, a tributary of the Ruisseau de Rivesecco, another tributary of the Restonica. The D623 road follows the river for most of its course. Tourism The valley lies in the Monte Rotondo massif and contains Lac de Melu at and Lac de Capitellu at . It is accessible by the narro ...

Pyrenees
The Pyrenees (; es, Pirineos ; french: Pyrénées ; ca, Pirineu ; eu, Pirinioak ; oc, Pirenèus ; an, Pirineus) is a mountain range straddling the border of France and Spain. It extends nearly from its union with the Cantabrian Mountains to Cap de Creus on the Mediterranean coast. It reaches a maximum altitude of at the peak of Aneto. For the most part, the main crest forms a divide between Spain and France, with the microstate of Andorra sandwiched in between. Historically, the Crown of Aragon and the Kingdom of Navarre extended on both sides of the mountain range. Etymology In Greek mythology, Pyrene is a princess who gave her name to the Pyrenees. The Greek historian Herodotus says Pyrene is the name of a town in Celtic Europe. According to Silius Italicus, she was the virgin daughter of Bebryx, a king in Mediterranean Gaul by whom the hero Hercules was given hospitality during his quest to steal the cattle of Geryon during his famous Labours.

Indel
Indel is a molecular biology term for an insertion or deletion of bases in the genome of an organism. It is classified among small genetic variations, measuring from 1 to 10 000 base pairs in length, including insertion and deletion events that may be separated by many years, and may not be related to each other in any way. A microindel is defined as an indel that results in a net change of 1 to 50 nucleotides. In coding regions of the genome, unless the length of an indel is a multiple of 3, it will produce a frameshift mutation. For example, a common microindel which results in a frameshift causes Bloom syndrome in the Jewish or Japanese population. Indels can be contrasted with a point mutation. An indel inserts or deletes nucleotides from a sequence, while a point mutation is a form of substitution that ''replaces'' one of the nucleotides without changing the overall number in the DNA. Indels can also be contrasted with Tandem Base Mutations (TBM), which may result from fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Proteorhodopsin
Proteorhodopsin (also known as pRhodopsin) is a family of transmembrane proteins that use retinal as a chromophore for light-mediated functionality, in this case, a proton pump. pRhodopsin is found in marine planktonic bacteria, archaea and eukaryotes ( protae), but was first discovered in bacteria. Its name is derived from proteobacteria (now called Pseudomonadota) that were named after Ancient Greek Πρωτεύς (Proteus), an early sea god mentioned by Homer as "Old Man of the Sea", Ῥόδος (rhódon) for "rose", due to its pinkish color, and ὄψις ( opsis) for "sight". Some members of the family, Homologous rhodopsin-like pigments, i.e. bacteriorhodopsin (of which there are more than 800 types) have Sensory Functions like opsins, integral for visual phototransduction. Many of these sensory functions are unknown – for example, the function of Neuropsin in the human retina. Members are known to have different absorption spectra including green and blue visibl ...

Corsica
Corsica ( , Upper , Southern ; it, Corsica; ; french: Corse ; lij, Còrsega; sc, Còssiga) is an island in the Mediterranean Sea and one of the 18 regions of France. It is the fourth-largest island in the Mediterranean and lies southeast of the French mainland, west of the Italian Peninsula and immediately north of the Italian island of Sardinia, which is the land mass nearest to it. A single chain of mountains makes up two-thirds of the island. , it had a population of 349,465. The island is a territorial collectivity of France. The regional capital is Ajaccio. Although the region is divided into two administrative departments, Haute-Corse and Corse-du-Sud, their respective regional and departmental territorial collectivities were merged on 1 January 2018 to form the single territorial collectivity of Corsica. As such, Corsica enjoys a greater degree of autonomy than other French regional collectivities; for example, the Corsican Assembly is permitted to exercise ...

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'').
