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:
“To expect to increase prices and then to maintain them at a higher level by means of a plan which must of necessity increase production while decreasing consumption is to fly in the face of an economic law as well established as any law of nature.”
—Calvin Coolidge (1872–1933)
“Every production of an artist should be the expression of an adventure of his soul.”
—W. Somerset Maugham (1874–1965)
“The heart of man ever finds a constant succession of passions, so that the destroying and pulling down of one proves generally to be nothing else but the production and the setting up of another.”
—François, Duc De La Rochefoucauld (1613–1680)
