Production of Bacterial Cellulose by Acetobacter Xylinum: Effects of Carbon/nitrogen-ratio on Cell Growth and Metabolite Production
The effects of carbon/nitrogen ratios on production of bacterial cellulose (BC), by submerged cultivation of Acetobacter xylinum NUST4.2, were investigated using central composite design and response surface analysis. The accumulation of metabolite was linked to cell growth. Amongst organic sources, peptone was favorable for BC production, while glucose was observed as the best carbon source. T...
متن کاملSynthesis 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 کاملMathematical Modeling Of Bacterial Cellulose Production By Acetobacter Xylinum Using Rotating Biological Fermentor
Bacterial cellulose (BC) has a basic cellulose structure that gives high purity, high crystalline ability, high mechanical strength, and high water holding capacity. During the last few decades, BC has gained as an important biomaterial because of these unique physical and chemical characteristics. BC is synthesized by Acetobacter xylinum extracellularly in a suitable substrate media. Researche...
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 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...
