Acetobacter Rasens
''Acetobacter'' is a genus of acetic acid bacteria. Acetic acid bacteria are characterized by the ability to convert ethanol to acetic acid in the presence of oxygen. Of these, the genus ''Acetobacter'' is distinguished by the ability to oxidation, oxidize lactic acid, lactate and acetate into carbon dioxide and water. Bacteria of the genus ''Acetobacter'' have been isolated from industrial vinegar fermentation processes and are frequently used as fermentation Fermentation starter, starter cultures. History of research The acetic fermentation was demonstrated by Louis Pasteur, who discovered the first acetobacter - ''Acetobacter aceti'' - in 1864. In 1998, two strains of ''Acetobacter'' isolated from red wine and cider vinegar were named ''Acetobacter oboediens'' and ''Acetobacter pomorum''. In 2000, ''Acetobacter oboediens'' and ''Acetobacter intermedius'' were transferred to ''Gluconacetobacter'' on the basis of 16S rRNA sequencing. In 2002, ''Acetobacter cerevisiae'' and ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), 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, Hot spring, 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 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, such as hydrogen sulp ...
