Variovorax
''Variovorax'' is a Gram-negative and motile genus of bacteria from the family Comamonadaceae. It belong to the class called ''Betaproteobacteria.'' It is an aerobic bacteria and most of its species is found in soil and freshwater. The demographic distribution of this species is primarily in Europe, Asia and the Americas, as well as the polar regions. Its designated species is ''Variovorax paradoxus'' which arose from the species ''Alcaligenes paradoxus'' being grouped under the Variovorax genus. ''Variovorax paradoxus'' constitutes to the methylotrophic microbiota of the human mouth. References Comamonadaceae Articles containing video clips Bacteria genera {{Betaproteobacteria-stub ...

Variovorax Paradoxus
''Variovorax paradoxus'' is a gram negative, beta proteobacterium from the genus ''Variovorax''. Strains of ''V. paradoxus'' can be categorized into two groups, hydrogen oxidizers and heterotrophic strains, both of which are aerobic. The genus name Vario-vorax (various-voracious; devouring a variety of substrates) and species name para-doxus (contrary-opinion) reflects both the dichotomy of ''V. paradoxus'' metabolisms, but also its ability to utilize a wide array of organic compounds. Morphology and physiology ''V. paradoxus'' cells are curved rods in shape, with dimensions of 0.3-0.6 x 0.7-3.0 μm in size and normally occur as either single or pairs of cells. Typically, cells have 1-3 peritrichous, degenerate flagella. Colonies of ''V. paradoxus'' are yellow-green in colour, due to the production of carotenoid pigments, and often have an iridescent sheen. Colony shape is normally convex, round and smooth, but can also display flat, undulate margins. ''V. paradoxus'' grows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
