Uzgoj i permeabilizacija stanica Ralstonia eutropha H16
In order to reduce the use of fossil fuels as an energy source, the use of green alternative fuels, such as hydrogen, is being promoted. Of particular interest is the production of biohydrogen, which is based on the decomposition of organic substances (e.g. organic waste) by microorganisms.

Staphyloferrin B, a Citrate Siderophore of Ralstonia eutropha
Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 1999 Abstract The structure and stereochemistry of the siderophore isolated from the culture medium of Ralstonia eutropha (formerly Alcaligenes eutrophus) could be elucidated as staphyloferrin B by spectroscopic methods and chemical degradation.

Ethanethiol degradation by Ralstonia eutropha
Biotechnology and Bioprocess Engineering, 2013In the present study, a pure culture of Ralstonia eutropha was used to degrade gaseous ethanethiol. Ethane thiol at various initial concentrations ranging from 115 to 320 mg/m3 was degraded almost completely within 120 ∼ 168 h, while at higher concentrations up to 452 mg/m3, removal efficiency declined.

Ralstonia eutropha as a biocatalyst for desulfurization of dibenzothiophene
Bioprocess and Biosystems Engineering, 2017The potential of Ralstonia eutropha as a biocatalyst for desulfurization of dibenzothiophene (DBT) was studied in growing and resting cell conditions. The results of both conditions showed that sulfur was removed from DBT which accompanied by the formation of 2-hydroxybiphenyl (2-HBP).

Occurrence and expression of tricarboxylate synthases in Ralstonia eutropha
Applied Microbiology and Biotechnology, 20062-Methylcitrate synthase (2-MCS1) and citrate synthase (CS) of Ralstonia eutropha strain H16 were separated by affinity chromatography and analyzed for their substrate specificities. 2-MCS1 used not only the primary substrate propionyl-CoA but also acetyl-CoA and, at a low rate, even butyryl-CoA and valeryl-CoA for condensation with oxaloacetate.

Quantifying the surface characteristics and flocculability of Ralstonia eutropha
Applied Microbiology and Biotechnology, 2008The microbial surface and flocculability were qualitatively characterized through the combination of the surface thermodynamic and the extended DLVO approaches, with Ralstonia eutropha, a polyhydroxybutyrate-producing bacterium, as an example. The negativity of the zeta potential of R.

The synthesis of hydroxybutyrate and hydroxyvalerate copolymers by the bacterium Ralstonia eutropha
Microbiology, 2005The paper deals with the study of the synthesis of 3-hydroxybutyrate (3HB) and 3-hydroxyvalerate (3HV) copolymers by the bacterium Ralstonia eutropha B-5786 grown under different carbon nutrition conditions (growth on carbon dioxide, fructose, and CO2-valerate and fructose-valerate mixtures). The parameters to be analyzed included the yield of biomass,

Production and purification of self-assembling peptides in Ralstonia eutropha
Protein Expression and Purification, 2006Self-assembling peptides have emerged as an attractive scaffold material for tissue engineering, yet the expense associated with solid phase chemical synthesis has limited their broad use. In addition, the fidelity of chemical synthesis constrains the length of polypeptides that can be produced homogeneously by this method.

Enzymatic recovery and purification of polyhydroxybutyrate produced by Ralstonia eutropha
Journal of Biotechnology, 2006Polyhydroxybutyrate (PHB) is the most studied among a wide variety of polyhydroxyalkanoates, bacterial biodegradable polymers known as potential substitutes for conventional plastics. This work aimed at evaluating the use of enzymes to recover and purify the PHB produced by Ralstonia eutropha DSM545.
