Entwurf und Verwendung eines Microarrays zur Untersuchung des Genistein-Stimulons bei Bradyrhizobium japonicum
Das Bakterium Bradyrhizobium japonicum ist wie andere Rhizobien in der Lage mit Pflanzen der Familie Fabales (Leguminosen) eine Symbiose einzugehen. Im symbiontischen Zustand fixieren die Mikrosymbionten atmosphärischen, molekularen Stickstoff und stellen diesen den Pflanzen in verwertbarer Form …

Chemolithotrophic nitrate dependent growth of Rhizobium japonicum on carbon monoxide and its relationship to hydrogenase activity
Anaerobic chemolithotrophic growth of Rhizobium japonicum occurred in the presence of carbon monoxide with nitrate serving as the electron acceptor. Under conditions where the atmospheric concentrations of CO were varied; the cells grew in up to 50% (v/v) CO. Optimum growth was observed in the …

Use of nitrous oxide as the terminal electron acceptor during growth and respiration of Bradyrhizobium Japonicum USDA 143
Bradyrhizobium japonicum USDA 143 grew chemoorganotrophically when supplied with exogenous nitrous oxide as the terminal electron acceptor, or as the alternate terminal electron acceptor to nitrate under anoxic conditions. Cell growth and dissimilatory N₂O reduction were significantly inhibited by …

The symbiotic interaction of Bradyrhizobium japonicum with bambara groundnut and cowpea and the effects of NOD gene-inducers, daidzein and genistein
The aim of this project was to investigate whether nodulation, and nitrogen concentration of legumes can be increased by providing additional nod geneinducer compounds. Both daidzein and genistein are nod gene-inducers for rhizobia nodulating cowpea, bambara groundnut, soybean and the common bean.

Silver Nanoparticles and the Plant-Associating Abilities of Rhizobiaceae Bacteria
… bacteria. Respiration analysis of Bradyrhizobium japonicum, Azospirillum brasilense, and Agrobacterium tumefaciens has revealed that AgNPs can negatively impact the growth and survival of these bacterial species, with B. japonicum being the most susceptible. Additionally, swimming motility assays …
