An Investigation of Acetobacter aceti N5-Carboxyaminoimidazole Ribonucleotide Mutase and Its purE-purK Operon
<italic>Acetobacter aceti</italic> oxidizes ethanol to acetic acid. While the membrane-permeable acetic acid is toxic to many bacteria, A. aceti survives exposure to acetic acid by tolerating cytoplasmic acidification. The ability to tolerate an acidic cytoplasm suggests that proteins from A. aceti …

A Specialized Citric Acid Cycle Requiring Succinyl-Coenzyme A (CoA):Acetate CoA-Transferase (AarC) Confers Acetic Acid Resistance on the Acidophile Acetobacter aceti
… from the industrial vinegar-production strain Acetobacter aceti 1023 and the process by which cytoplasmic acetic acid is "overoxidized" to carbon dioxide. Acetate overoxidation in A. aceti strain 1023 is catalyzed by a variant citric acid cycle: CAC) that lacks succinyl-coenzyme A: CoA) …

Electromagnetic Control of Biological Assembly
… This work describes how the motion of Acetobacter xylinum can be controlled by electric fields while the bacteria simultaneously produce nanocellulose, resulting in networks with aligned fibers. Since the electrolysis of water due to the application of electric fields produces the …

Characterization of a major cluster of genes involved in nitrogen fixation and another required for indole-3-acetic acid biosynthesis in the sugarcane endophyte, Acetobacter diazotrophicus
Acetobacter diazotrophicus is a true endophyte of sugarcane and is often found in plants grown in agricultural areas of low nitrogen fertilizer input. Results from our laboratory, using mutant strains of A. diazotrophicus unable to fix nitrogen, have shown that there are two beneficial effects of …

Development of an electronic paper prototype on bacterial cellulose using electrochromic systems
… was synthesized in a culture of NQ-5 strain of Acetobacter xylinum in the standard glucose-rich (SH) medium. Bacterial cellulose thus formed was dimensionally stable, had a paper-like appearance and had a unique microfibrillar nanostructure. This bacterial cellulose was made an electrically …

Analysis of Hopanoids From Three Psychrophilic Marine Bacterial Strains
… might synthesize hopanoids. The bacterium, Acetobacter aceti subsp. aceti, known to contain hopanoids, was also analyzed as a control. Cellular lipids were extracted from freeze-dried cells using a chloroform/methanol/water solvent system. Crude extracts were treated with a solution of …

Pineapple Vinegar to Enhance Shelf Life of Carrot and Mango in Tanzania
… and was fermented with Saccharomyces cereviciae, Acetobacter pasteurianus, and Gluconobacter oxydans. Levels of acetic acid were measured in the vinegar produced. High production (5.8%) of acetic acid was observed with pineapple juice concentrated to 130 Brix with the combination of Saccharomyces …

The impact of chlortetracycline on Drosophila melanogaster and Aedes aegypti
… diversity of Drosophila was predominantly Acetobacter. Bacterial elimination through egg dechorionation yielded some similar results to chlortetracycline treatment. However, fecundity and life-span was not significantly affected. Microarray analysis established a significant reduction in …
