Gluconobacter oxydans, a biotechnologically relevant species which incompletely oxidizes a large variety of carbohydrates, alcohols, and related compounds, contains a gene for pyruvate decarboxylase (PDC). This enzyme is found only in very few species of bacteria where it is normally involved in anaerobic ethanol formation via acetaldehyde. In order to(More)
Acetic acid bacteria such as Gluconobacter oxydans are used in several biotechnological processes due to their ability to perform rapid incomplete regio- and stereo-selective oxidations of a great variety of carbohydrates, alcohols, and related compounds by their membrane-bound dehydrogenases. In order to understand the growth physiology of industrial(More)
Gluconobacter oxydans, like all acetic acid bacteria, has several membrane-bound dehydrogenases, which oxidize a multitude of alcohols and polyols in a stereo- and regio-selective manner. Many membrane-bound dehydrogenases have been purified from various acetic acid bacteria, but in most cases without reporting associated sequence information. We(More)
For the detailed molecular analysis, genomic modification, and application of acetic acid bacteria such as Gluconobacter in biotechnological processes, a simple markerless deletion system is essential. The available methods have either low efficiencies or their applicability is restricted to strains containing an upp mutation. We now developed a method(More)
The unusual aspect of dream consciousness which has been called "dream bizarreness" may be defined as impossibility or improbability in the domains of dream plot, cognition and affect. The bizarre features of dreams may be divided into three broad categories: discontinuities, incongruities and uncertainties. Discontinuities are interruptions in(More)
Acetic acid bacteria are used in biotechnology due to their ability to incompletely oxidize a great variety of carbohydrates, alcohols, and related compounds in a regio- and stereo-selective manner. These reactions are catalyzed by membrane-bound dehydrogenases (mDHs), often with a broad substrate spectrum. In this study, the promoters of six mDHs of(More)
