In nature A. xylinum is found in soil and is commonly found on rotting fallen fruits. It’s exceptional ability to produce cellulose has made it a common choice for researchers studying the biosynthesis of cellulose. Micrococcus luteus was originally isolated by Alexander Fleming in 1929 as Micrococcus lysodeikticus.It was the primary experimental microbe used in Fleming's discovery of lysozyme. The microbe can be found in a variety of environments including soil, water, animals, and some dairy products.Bacterial cellulose was produced by static cultivation of Glucanacetobacter xylinum ATCC 10245 in different culture media such as Brain Heart Agar, Luria Bertani Agar /Broth, Brain Heart Infusion, Hestrin-Schramm and medium no. 125. Cultivation of bacterium was conducted in various culture vessels with different surface area.on BC synthesis using A. xylinum as a model bacteria were started by Hestrin et al., (1947, 1954), who proved that resting and lyophilized Acetobacter cells synthesized cellulose in the presence of glucose and oxygen. Later, Colvin (1957) detected cellulose synthesis in samples containing cell-free extract of A. xylinum, glucose and ATP.

Gluconacetobacter xylinus (reclassified from Acetobacter xylinum) is the most widely studied species of bacteria that produces cellulose. Under special culturing conditions, the bacteria secrete cellulose microfibrils, producing a thick gel called pellicle, composed of cellulose microfibrils and 97% water, on the surface of the liquid medium. Swelled bacterial cellulose (ex. Acetobacter xylinum), in its never-dried state with much smaller fibrils (≈ 1%) than from plants, exhibits pseudo-plastic viscosity like xanthan gels. However, this viscosity is not lost at high temperatures and low shear rates as the cellulose can retain its structure.Acetobacter diazotrophicus was not able to transport sucrose and its ability to grow on this disaccharide was explained by the presence of an extracellular enzyme with saccharolytic activity.Key words: Acetobacter diazotrophicus, carbon–nitrogen metabolism, extracellular saccharolytic activity, sucrose–succinate uptake.

A mutant strain of Acetobacter xylinum produces cellulose of anomalous band-like form ('native band'), and this material has been found to be cellulose II, presumably having a folded-chain structure (according to recent work by Kuga et al.).A novel artificial skin of BC has been biosynthesized by Acetobacter xylinum (CCTCC M207163) [7]. BC is the substratum of composite artificial skin. 2.1.Preparation of artificial skin Acetobacter xylinum was inoculated and cultured at 30 C in static culture medium which contained 10% glucose, 1% yeast and 2% CaCO3.Nata-de-coco, a bacterial cellulose product, which is usually prepared by Acetobacter xylinum grown in mature coconut water, is a quite popular snack in Vietnam and other countries.It is argued that this integrated manufacturing approach to fiber-reinforced thermoplastic nanocomposites affords a good flexibility for tailoring morphology and properties. These results further pose the question of the necessity to remove bacterial cells to achieve desirable materials properties in biologically derived products.Amtex manufacturing
