Bacteria
Bacteria (; : bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), domain of Prokaryote, 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 the air, soil, water, Hot spring, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the nitrogen fixation, fixation of nitrogen from the Earth's atmosphere, atmosphere. The nutrient cycle includes the decomposition of cadaver, 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, suc ...

Pseudomonadota
Pseudomonadota (synonym "Proteobacteria") is a major phylum of gram-negative bacteria. Currently, they are considered the predominant phylum within the domain of bacteria. They are naturally found as pathogenic and free-living (non- parasitic) genera. The phylum comprises six classes ''Acidithiobacillia, Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Hydrogenophilia'', and '' Zetaproteobacteria.'' The Pseudomonadota are widely diverse, with differences in morphology, metabolic processes, relevance to humans, and ecological influence. Classification American microbiologist Carl Woese established this grouping in 1987, calling it informally the "purple bacteria and their relatives". The group was later formally named the 'Proteobacteria' after the Greek god Proteus, who was known to assume many forms. In 2021 the International Committee on Systematics of Prokaryotes designated the synonym Pseudomonadota, and renamed many other prokaryotic phyla as well. Th ...

Alphaproteobacteria
''Alphaproteobacteria'' or ''α-proteobacteria'', also called ''α-Purple bacteria'' in earlier literature, 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, although some of its intracellular parasitic members lack peptidoglycan and are consequently gram variable. Characteristics The ''Alphaproteobacteria'' are a diverse taxon and comprise 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyphomicrobiales
The Hyphomicrobiale' (synonym Rhizobiales) 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,'' an important tool in genetic engineering.

Dreisam River
The Dreisam (Celtic: ''*tragisamā'', "the very fast one") is a 29 km long river (48.8 km including its source river Rotbach), and a tributary of the Elz in the German state of Baden-Württemberg. The waters of the Dreisam feed the famous Freiburg Bächle runnels. Geography The Dreisam begins in the Dreisam Valley (''Dreisamtal'') which is located in the Southern Black Forest (''Südschwarzwald''). The origin of the river can be found close to a bridge on the ''Landesstraße'' 127 which leads from Kirchzarten to Stegen. Here, two streams, the Rotbach and Wagensteinbach, meet to form the Dreisam river. This confluence is located in the western part of the Southern Black Forest Nature Park below the so-called Höllental, where the Rotchbach flows through, and the Wagensteig valley. From there on the Dreisam, which was canalized, flows towards the west and reaches Freiburg at the eastern end of Ebnet. Along the way the Dreisam meets the Krummbach and Brugga, two streams ...

Freiburg Im Breichsgau
Freiburg im Breisgau or simply Freiburg is the fourth-largest city of the German state of Baden-Württemberg after Stuttgart, Mannheim and Karlsruhe. Its built-up area has a population of about 355,000 (2021), while the greater Freiburg metropolitan area ("Einzugsgebiet") has about 660,000 (2018). Freiburg is located at the southwestern foothills of the Black Forest, on the Dreisam River, a tributary of the Elz. It is Germany's southwestern- and southernmost city with a population exceeding 100,000. It lies in the Breisgau, one of Germany's warmest regions, in the south of the Upper Rhine Plain. Its city limits reach from the Schauinsland summit () in the Black Forest to east of the French border, while Switzerland is to the south. The city is situated in the major wine-growing region of Baden and, together with Offenburg, serves as a tourist entry-point to the scenic Black Forest. According to meteorological statistics, Freiburg held the all-time German temperature record ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
