TranscriptomicsInfluence of oxygen limitation, absence of the cytochrome bc1 complex and low pH on global gene expression in Gluconobacter oxydans 621H using DNA microarray technology
The genome-wide transcriptional responses of the strictly aerobic -proteobacterium Gluconobacter oxydans 621H to oxygen limitation, to the absence of the cytochrome bc1 complex, and to low pH were studied using DNA microarray analyses. Oxygen limitation caused expression changes of 486 genes, repres...

TranscriptomicsEvidence for a key role of cytochrome bo3 oxidase in respiratory energy metabolism of Gluconobacter oxydans
The obligatory aerobic acetic acid bacterium Gluconobacter oxydans oxidizes a variety of substrates in the periplasm by membrane-bound dehydrogenases, which transfer the reducing equivalents to ubiquinone. Two quinol oxidases, cytochrome bo3 and cytochrome bd, then catalyze transfer of the electrons...

TranscriptomicsGlucose catabolism via a partially cyclic pentose phosphate pathway in Gluconobacter oxydans 621H: a combined fluxomics and transcriptomics analysis
In this study, the distribution and regulation of periplasmic and cytoplasmic carbon fluxes in Gluconobacter oxydans 621H with glucose were studied by 13C-based metabolic flux analysis (13C-MFA) in combination with transcriptomics and enzyme assays. For 13C-MFA, cells were cultivated with specifical...

TranscriptomicsMutational analysis of the pentose phosphate pathway and the Entner-Doudoroff pathway in Gluconobacter oxydans reveals improved growth of an edd-eda deletion mutant on mannitol
The obligatory aerobic acetic acid bacterium Gluconobacter oxydans 621H oxidizes sugars and sugar alcohols primarily in the periplasm and only a small fraction is metabolized in the cytoplasm. The latter can occur either via the Entner-Doudoroff pathway (EDP) or via the pentose phosphate pathway (PP...
