Zur Struktur und Funktion regulatorischer Elemente des cbb-Regulons in Ralstonia eutropha
Für die autotrophe Assimilation von CO2 benötigt Ralstonia eutropha H16 die Enzyme des Calvin-Cyclus. Die genetische Kontrolle bei der wechselseitigen Umstellung des Kohlenstoffmetabolismus zwischen autotrophen und heterotrophen Bedingungen betrifft vorrangig die Transkription der cbb-Operone, …

Studies on the mechanism of polyhydroxybutyrate (PHB) granule formation in Ralstonia eutropha H16/
… formation in the model gram-negative bacterium, Ralstonia eutropha H16. In order to examine initiation and elongation of PHB polymerization in vivo, an N-terminally Strep2-tagged PHB synthase was isolated from R. eutropha using a strain in which the native phaC gene was replaced with the affinity …

Production of biofuels and biodegradable plastics from common waste substrates in engineered Ralstonia eutropha
Ralstonia eutropha, a Gram-negative proteobacterium, is capable of utilizing a plethora of simple and complex carbon sources derived from common waste streams. When experiencing nutrient stress in the presence of high carbons, R. eutropha can store carbon and energy in the form of …

Heavy Metal Resistance in the Genus Gluconobacter
… and sequencing to establish gene homology with Ralstonia eutropha, the most frequently studied Gram-negative bacterium exhibiting cadmium resistance. Amplification of two genes from the czc operon, known to encode cadmium, cobalt and zinc resistance in Ralstonia, was attempted in the three …

The role of the phasin PhaP in promoting polyhydroxybutyrate (PHB) granule formation in Caulobacter crescentus
… biosynthesis has primarily been carried out in Ralstonia eutropha, which accumulates PHB to 80% of its cell dry weight (cdw) under the appropriate growth conditions. However most organisms do not accumulate PHB to such extremes, thus we have focused our efforts on understanding whether what we …

Production of a soluble hydrogenase from R. Eutropha H16
… [Ni-Fe] uptake hydrogenase (SH) produced by Ralstonia eutropha H16. The research conducted in this project can be divided into two main parts. Firstly, bioprocess optimisation to produce and purify the SH from R. eutropha H16 was undertaken. Partially optimised batch-fermentations in …

Untersuchungen zur genetischen Regulation der CO<sub>2</sub>-Assimilation in <i>Ralstonia</i> spp.
Die autotrophe CO2-Assimilation erfolgt in Ralstonia eutropha H16 und Ralstonia metallidurans CH34 über den des Calvin-Benson-Bassham (CBB) Cyclus. Die Expression der beiden hoch homologen cbb-Operone cbbc und cbbp in R. eutropha H16 wird in erster Linie durch den LysR-Typ-Transkriptionsregulator …
