Nowadays, vinegar is industrially produced by mesophilic acetic acid bacteria (AAB). However, temperature fluctuation during acetous fermentation is inevitable, and may cause process disturbances. This can be mostly avoided using thermo-tolerant AAB. The main purpose of the present study was to isolate thermo-tolerant AAB. Fermentation performances were then evaluated. Twenty-eight different is...

Acetobacter cibinongensis Bacteremia in Human To the Editor: The genus Aceto-bacter belongs to the group of acetic acid bacteria that oxidize alcohols or sugars incompletely, leading to the accumulation of acetic acid. Acetic acid bacteria are of great industrial interest because of their use to produce vinegar from spirits, wine, beer, and cider in temperate regions of Europe, the Americas, an...

background bedsore is one of the major problems in all the societies as patients are confined to bed. due to antibiotic resistant strains being a significant obstacle for cure, many plants and herbs are being used by researchers as medicinal compounds. objectives the investigation of synergistic effect of cellulose biopolymer and papaver macrostomum extract on bedsores bacterial community. mate...

Cellulose triacetate prepared from bacterial cellulose of Acetobacter xylinum subsp. sucrofermentans BPR3001A showed a higher degree of polymerization and higher mechanical strength than that from the cotton linter. The fine fibrils of bacterial cellulose required only a short time for acetylation which preserved the high degree of polymerization.

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...

The terminal oxidase for ethanol oxidation in Acetobacter aced was purified as a complex consisting of four subunits (subunits I, II, III, and IV) with molecular masses of 72, 34, 21, and 13 kDa, respectively. Spectrophotometric analysis and catalytic properties determined with the purified enzyme showed that it belonged to a family of cytochrome a, (ba)-type ubiquinol oxidases. A polymerase ch...

It has previously been shown that cell-free extracts of Acetobacter subozydans possess two pathways for the oxidation of sorbitol (1). In the presence of DPN,l fructose is produced; with TPN, sorbose is formed. The primary purpose of this paper is to describe the separation of these two dehydrogenases from each other. The DPN enzyme free from TPN activity has been concentrated about lBfold, whe...

Acetobacter tropicalis Oregon-R-modENCODE strain BDGP1 was isolated from Drosophila melanogaster for functional host-microbe interaction studies. The complete genome comprises a single chromosomal circle of 3,988,649 bp with a G+C content of 56% and a conjugative plasmid of 151,013 bp.

We report here the complete genome sequences of the acetic acid bacteria (AAB) Acetobacter aceti TMW 2.1153, A. persici TMW 2.1084, and Neoasaia chiangmaiensis NBRC 101099, which secrete biotechnologically relevant heteropolysaccharides (HePSs) into their environments. Upon genome sequencing of these AAB strains, the corresponding HePS biosynthesis pathways were identified.
