Disease relevance of Gluconacetobacter

• Southern blot analysis and subsequent nucleotide sequencing predicted the presence of aatA orthologues in a variety of acetic acid bacteria belonging to the genera Acetobacter and Gluconacetobacter [1].
• The glnD gene of Gluconacetobacter diazotrophicus was isolated by complementation of the Azotobacter vinelandii glnD (nfrX) mutant strain MV17 using a pLAFR3 cosmid library [2].
• On the basis of 16S rRNA gene sequence similarities, strains DST GL01T and DST GL02T were shown to belong to the alpha-subclass of the Proteobacteria, and, in particular, to the genus Gluconacetobacter, in the Gluconacetobacter xylinus branch (98.5-100 %) [3].
• Azospirillum strains produced the highest concentrations of IAA (16.5-38 microg IAA/mg protein), whereas Gluconacetobacter and P. stutzeri strains produced lower concentrations of IAA ranging from 1 to 2.9 microg/mg protein in culture medium supplemented with tryptophan [4].
• Molecular cloning and expression in Escherichia coli of an exo-levanase gene from the endophytic bacterium Gluconacetobacter diazotrophicus SRT4 [5].

High impact information on Gluconacetobacter

• It has been shown for Gluconacetobacter xylinum that cellulose biosynthesis is allosterically regulated by bis-(3',5') cyclic diguanylic acid, whose synthesis/degradation depends on diguanylate cyclase/phosphodiesterase enzymatic activities [6].
• The endophytic diazotroph Gluconacetobacter diazotrophicus secretes a constitutively expressed levansucrase (LsdA, EC 2.4.1.10) to utilize plant sucrose [7].
• Indole-3-acetic acid biosynthesis is deficient in Gluconacetobacter diazotrophicus strains with mutations in cytochrome c biogenesis genes [8].
• Isolation and characterization of the glnD gene of Gluconacetobacter diazotrophicus, encoding a putative uridylyltransferase/uridylyl-removing enzyme [2].
• Gluconacetobacter diazotrophicus PAL3 was grown in a chemostat with N(2) and mixtures of xylose and gluconate [9].

Chemical compound and disease context of Gluconacetobacter

• Description of Gluconacetobacter sacchari sp. nov., a new species of acetic acid bacterium isolated from the leaf sheath of sugar cane and from the pink sugar-cane mealy bug [10].
• On the basis of the phylogenetic positioning of the strains, DNA reassociation studies, phenotypic tests and the presence of the Q10 ubiquinone, this new species was assigned to the genus Gluconacetobacter [10].
• Direct incorporation of glucosamine and N-acetylglucosamine into exopolymers by Gluconacetobacter xylinus (=Acetobacter xylinum) ATCC 10245: production of chitosan-cellulose and chitin-cellulose exopolymers [11].
• Using this method, fructose, acetate, and gluconacetan were monitored during batch fermentations of Gluconacetobacter xylinus 12281 using mid-infrared spectroscopy [12].
• Sugar cane (Saccharum spp.) variety SP 70-1143 was inoculated with Gluconacetobacter diazotrophicus strain PAL5 (ATCC 49037) in two experiments [13].

Anatomical context of Gluconacetobacter

• Some of these glycoproteins, previously labelled with fluorescein isothiocyanate, are able to bind to the cell wall of the sugarcane endophyte, N2-fixing Gluconacetobacter diazotrophicus, and largely removed after washing the bacterial cells with sucrose [14].

Gene context of Gluconacetobacter

• The results of DNA-DNA hybridizations, together with physiological and biochemical data, allowed genotypic and phenotypic differentiation between strains DST GL01T and DST GL02T and from the 11 validly published Gluconacetobacter species [3].
• Periplasmic glucose oxidation (by way of a pyrrolo-quinoline-quinone [PQQ]-linked glucose dehydrogenase [GDH]) was observed in continuous cultures of Gluconacetobacter diazotrophicus regardless of the carbon source (glucose or gluconate) and the nitrogen source (N(2) or NH(3)) [15].
