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 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 کاملConversion of Glycerol to Dihydroxyacetone by Immobilized Whole Cells of Acetobacter xylinum.
Enzymatic production of dihydroxyacetone (DHA) was studied by immobilization of the whole cells of acetic acid bacteria capable of oxidizing glycerol to DHA. Acetobacter xylinum A-9 cells immobilized in a polyacrylamide gel were selected as the most favorable enzyme preparation. The enzymatic properties of immobilized cells converting glycerol to DHA were investigated and compared with those of...

Nata de coco is a type of beverage component is a cellulose compound produced from coconut water through a process that involves microbial fermentation known as Acetobacter xylinum. To increase the economic value, shelf life, and the benefits of diversification do nata product of nata de coco wet a fiber-rich instant drink of nata de coco. This research used Completely Randomized Design (CRD) a...
متن کاملMetabolism of Dicarboxylic Acids in Acetobacter Xylinum.
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...
