We isolated thermotolerant Gluconobacter strains that are able to produce 5-keto-d-gluconic acid (5KGA) at 37 degrees C, a temperature at which regular mesophilic 5KGA-producing strains showed much less growth and 5KGA production. The thermotolerant strains produced 2KGA as the major

Gluconobacter oxydans DSM 2343 is known to catalyze the oxidation of glucose to gluconic acid, and subsequently, to 2-keto-D-gluconic acid (2-KGA) and 5-keto-D-gluconic acid (5-KGA), by membrane-bound and soluble dehydrogenases. In G. oxydans MF1, in which the membrane-bound gluconate-2-dehydrogenase complex

The chromosomal locus NP_636946 of Xanthomonas campestris DSM 3586 (ATCC 33913) which was earlier presumed to encode a quinoprotein glucose dehydrogenase has been cloned, expressed in Escherichia coli and the recombinant enzyme has been characterised. It was found to have

Acetic acid bacteria, especially Gluconobacter species, have been known to catalyze the extensive oxidation of sugar alcohols (polyols) such as D-mannitol, glycerol, D-sorbitol, and so on. Gluconobacter species also oxidize sugars and sugar acids and uniquely accumulate two different keto-D-gluconates

A bacterial strain, designated B13T, was isolated from spoiled red wine from the Dão region, Portugal. The strain was Gram-negative, strictly aerobic, rod-shaped and motile. Phylogenetic analysis on the basis of 16S rRNA gene sequences indicated that B13T belonged to
