Production
Bacteria from the genera Aerobacter, Acetobacter, Achromobacter, Agrobacterium, Alacaligenes, Azotobacter, Pseudomonas, Rhizobium, and Sarcina synthesize cellulose. However, only the Gluconacetobacter produce enough cellulose to justify commercial interest. The most extensively studied species is Gluconacetobacter xylinus, formerly known as Acetobacter xylinum and since reclassified into a different genus.
G. xylinus extrudes glucan chains from pores into the growth medium. These aggregate into microfibrils, which bundle to form microbial cellulose ribbons. Various kinds of sugars are used as substrate. Production occurs mostly at the interface of liquid and air.

Famous quotes containing the word production:
“[T]he asphaltum contains an exactly requisite amount of sulphides for production of rubber tires. This brown material also contains ichthyol, a medicinal preparation used externally, in Websters clarifying phrase, as an alterant and discutient.”
—State of Utah, U.S. public relief program (1935-1943)
“An art whose limits depend on a moving image, mass audience, and industrial production is bound to differ from an art whose limits depend on language, a limited audience, and individual creation. In short, the filmed novel, in spite of certain resemblances, will inevitably become a different artistic entity from the novel on which it is based.”
—George Bluestone, U.S. educator, critic. The Limits of the Novel and the Limits of the Film, Novels Into Film, Johns Hopkins Press (1957)
“Every production of an artist should be the expression of an adventure of his soul.”
—W. Somerset Maugham (18741965)
