Acetobacter

[ə′sēd·ō‚bak·tər]
(microbiology)
A genus of gram-negative, aerobic bacteria of uncertain affiliation comprising ellipsoidal to rod-shaped cells as singles, pairs, or chains; they oxidize ethanol to acetic acid. Also known as acetic acid bacteria; vinegar bacteria.

In the other approach, cellulose can be prepared from the bacterial species Acetobacter xylinum, which is one of the most effective species for bacterial cellulose preparation and has high percent yield and uniform size and shape.
Bio-fibers of the substrate are produced with bacteria (mainly acetobacter xylinum) and plant-derived materials like coconut milk and grain mash via bio-fermentation technology.

Similarly, in Komagataeibacter xylinus (formerly Acetobacter xylinum) A-L interface biofilms, growth is limited to a top layer of 50-100 [micro]m by [O.sub.2] diffusion from above and nutrient diffusion from below [35].
For example, bacterial cellulose (BC) produced by Acetobacter xylinum is used in food processing because of its chemically pure form of cellulose, high water holding capacity and tensile strength, high fiber content, and low cost.
