Acetobacterium Bakii
''Acetobacterium'' is a genus of anaerobic, Gram-positive bacteria that belong to the Eubacteriaceae family. The type species of this genus is ''Acetobacterium woodii''. The name, ''Acetobacterium'', has originated because they are acetogens, predominantly making acetic acid as a byproduct of anaerobic metabolism. Most of the species reported in this genus are homoacetogens, i.e. solely producing acetic acid as their metabolic byproduct. They should not be confused with acetic acid bacteria which are aerobic, Gram-negative Alphaproteobacteria. Other acetogens use the Wood–Ljungdahl pathway The Wood–Ljungdahl pathway is a set of biochemical reactions used by some bacteria. It is also known as the reductive acetyl-coenzyme A (Acetyl-CoA) pathway. This pathway enables these organisms to use hydrogen as an electron donor, and carb ... to reduce CO or CO2 and produce acetate, but what distinguishes ''A.woodii'' and other ''Acetobacterium'' from other acetogens is that it c ...

Acetobacter
''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 oxidize 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 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 '' Acetobacter malorum'' were identified b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
