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 5-ketogluconate (5-KGA)-forming membrane quinoprotein, gluconate dehydrogenase, was isolated from Gluconobacter suboxydans strain IFO 12528 and partially sequenced. Partial sequences of five internal tryptic peptides were elucidated by mass spectrometry and used to isolate the two adjacent genes encoding the

For the conversion of glucose to 5-keto-D-gluconate (5-KGA), a precursor of the industrially important L-(+)-tartaric acid, Gluconobacter strains were genetically engineered. In order to increase 5-KGA formation, a plasmid-encoded copy of the gene encoding the gluconate:NADP-5 oxidoreductase (gno) was overexpressed

Gluconobacter oxydans DSM 2343 (ATCC 621H)catalyzes the oxidation of glucose to gluconic acid and subsequently to 5-keto-D-gluconic acid (5-KGA), a precursor of the industrially important L-(+)-tartaric acid. To further increase 5-KGA production in G. oxydans, the mutant strain MF1 was

Applied microbiology and biotechnology, 73(2), 443-451 (2006-07-06)
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
