Alternative 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 کاملAcetobacter xylinum Mutant with High and an Ordered Structure Cellulose Productivity
Acetobacter xylinum sllbsp. sucrojlermentans BPR2001, a cellulose-producing bacterillm, that was newly isolated from a natural source, prodllced large amounts of the water-soluble po]ysaccharide, acetan. UDP-glucose is known to be the direct precllrsor in the synthetic pathways of both cellulose and acetan. We attempted to breed mutant strains and succeeded in obtalning olle, BPR3001A, which pr...
متن کاملRemoval of Mercury from chlor-alkali Industry Wastewater using Acetobacter xylinum Cellulose
In this study, the removal of mercury ions by cellulose of Acetobacter xylinum was investigated in the synthetic and chlor-alkali wastewater. Biofilms of Acetobacter xylinum were grown in laboratory column bioreactors. The biofilms were continuously treated with sterile synthetic model wastewater or nonsterile, neutralized chloralkali wastewater.The extent of adsorption was studied as function ...

Cellulose was the most abundant polymer or polysaccharide that presents as the structural component of the primary cell wall of green plants but also signify for microbial extracellular polymer. The production of cellulose by microorganism such as Acetobacter xylinum sp. was most favored by researchers because the cellulose that produced was extremely pure and had a higher degree of polymerizat...

Benziman, Moshe (The Hebrew University of Jerusalem, Jerusalem, Israel), and A. Abeliovitz. Metabolism of dicarboxylic acids in Acetobacter xylinum. J. Bacteriol. 87:270-277. 1964.-During the oxidation of fumarate or l-malate by whole cells or extracts of Acetobacter xylinum grown on succinate, a keto acid accumulated in the medium in considerable amounts. This acid was identified as oxaloaceti...
