Gluconobacter oxydans is unsurpassed by other organisms in its ability to incompletely oxidize a great variety of carbohydrates, alcohols and related compounds. Furthermore, the organism is used for several biotechnological processes, such as vitamin C production. To further our understanding of its overall metabolism, we sequenced the complete genome of G. oxydans 621H. The chromosome consists of 2,702,173 base pairs and contains 2,432 open reading frames. In addition, five plasmids were… 

Physiology of Acetic Acid Bacteria in Light of the Genome Sequence of Gluconobacter oxydans

Based on the genome sequence of Gluconobacteroxydans, light is shed on the central carbon metabolism, the composition of the respiratory chain and the analysis of uncharacterized oxidoreductases, which are of major importance in the process of incomplete oxidation.

Global mRNA decay and 23S rRNA fragmentation in Gluconobacter oxydans 621H

The very short mRNA half-lives of the H+-ATP synthase, which is likely responsible for the ATP-proton motive force interconversion in G. oxydans under many or most conditions, is notably in contrast to mRNA decay data from other bacteria.

Identification of Gradient Promoters of Gluconobacter oxydans and Their Applications in the Biosynthesis of 2-Keto-L-Gulonic Acid

The low activity of SDH was found to hamper the high yield of 2-KLG, and enhancing the expression ofSDH was achieved by screening the suitable promoters based on RNA sequencing data, and a series of gradient promoters were obtained, including two strong shuttle promoters and six strongest promoters were used to overexpress SDH in G. oxydans WSH-003.

Characterization of membrane-bound dehydrogenases of Gluconobacter oxydans 621H using a new system for their functional expression
