Dynamic model for isopropanol production by Cupriavidus necator
IFAC Proceedings Volumes, 2014Abstract The Hybrid Cybernetic Model (HCM) enables the simulation of metabolic fluxes by using Elementary Modes Analysis and taking into account of selected cellular regulations. These latter are represented by cybernetic control variables. In this study, a simplified metabolic network was established in order to isolate a subset of Elementary Modes,

Engineering Cupriavidus necator H16 for heterotrophic and autotrophic production of myo-inositol
Bioresource Technology, 2022Bioconversion of sustainable feedstocks to commodity chemicals is considered as an effective solution for transforming the fossil-based economy into a carbon-neutral model. Here, the CO2-fixing bacterium Cupriavidus necator H16 was exploited for myo-inositol production from renewable substrates.

Knallgasbakterien – neue Synthesewege mit Cupriavidus necator
BIOspektrum, 2018Climate change and the finite nature of fossil fuels raise the need for the fixation of CO2 and conversion into traditionally petroleum-derived chemicals. With Cupriavidus necator as an easily genetically modifiable biocatalyst, a wide range of products, e. g. polymers, platform chemicals, biofuels, and terpenes, can be accessed.

Use of enzymes in extraction of polyhydroxyalkanoates produced by Cupriavidus necator
Biotechnology Progress, 2012AbstractPoly(3‐hydroxybutyrate) (P(3HB)) and its copolymer poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (P(3HB‐co‐3HV), are biodegradable thermoplastic polymers. They are members of the polyhydroxyalkanoate (PHA) family, synthesized and accumulated as a carbon and energy reserve by a variety of microorganisms.

Deconvolution of reduction potentials of formate dehydrogenase from Cupriavidus necator
JBIC Journal of Biological Inorganic Chemistry, 2019The formate dehydrogenase enzyme from Cupriavidus necator (FdsABG) carries out the two-electron oxidation of formate to CO2, but is also capable of reducing CO2 back to formate, a potential biofuel. FdsABG is a heterotrimeric enzyme that performs this transformation using nine redox-active cofactors: a bis(molybdopterin guanine dinucleotide) (bis-MGD ...

Unraveling the predator-prey relationship of Cupriavidus necator and Bacillus subtilis
Microbiological Research, 2016Cupriavidus necator is a non-obligate bacterial predator of Gram-negative and Gram-positive bacteria. In this study, we set out to determine the conditions, which are necessary to observe predatory behavior of C. necator. Using Bacillus subtilis as a prey organism, we confirmed that the predatory performance of C.

External stress factors in the form of ionic species or temperature increases have been shown to produce a stress response leading to enhanced PHA production. The effect of five different NaCl concentrations, namely 3.5, 6.5, 9, 12 and 15 g/l NaCl on PHA productivity using Cupriavidus necator has been investigated alongside a control (no added NaCl). A
