Synthesis of Cellulose by Acetobacter Xylinum
Appearance of cellulose microfibrils in the medium of a suspension of cells of Acetobacter xylinum in buffered glucose solution was preceded by a stage during which the cellulose in the medium was amorphous within the available resolution. The size of the vertical axis of the microfibrils of the bacterial cellulose was found on the basis of measurement of shadow length to be only about 16 A. In...
متن کاملAlternative Environmental Roles for Cellulose Produced by Acetobacter xylinum.
The cellulose-producing bacterium Acetobacter xylinum has been considered a strict aerobe, and it has been suggested that the function of cellulose is to hold cells in an aerobic environment. In this study, we showed that A. xylinum is capable of growing microaerophilically. Cellulose pellicles provided significant protection to A. xylinum cells from the killing effects of UV light. In experime...

متن کاملFormation of D-glucose, cellobiose, and other saccharides during synthesis of cellulose by Acetobacter acetigenum in a lactate-buffered glycerol medium.
Particulars of Microorganism and Its Cultivation-The strain of A. czcetigenum used was NCIB 8132 from the National Collection of Industrial Bacteria, Department of Scientific and Industrial Research, Teddington, Middlesex, England. The defined medium, made with distilled water, contained (grams per liter): KHZPOI, 2.0; MgS04.7 HSO, 1.0; FeS04.7 HZO, 0.01; (NH&HP04, 2.5; calcium n-pantothenate, ...
متن کاملEnhancement of cellulose production by expression of sucrose synthase in Acetobacter xylinum.
Higher plants efficiently conserve energy ATP in cellulose biosynthesis by expression of sucrose synthase, in which the high free energy between glucose and fructose in sucrose can be conserved and used for the synthesis of UDP-glucose. A mixture of sucrose synthase and bacterial cellulose synthase proceeded to form UDP-glucose from sucrose plus UDP and to synthesize 1,4-beta-glucan from the su...
