Respiratory membrane endo-hydrogenase activity in the microaerophile Azorhizobium caulinodans is bidirectional. [PDF]
PLoS ONE, 2012 BACKGROUND: The microaerophilic bacterium Azorhizobium caulinodans, when fixing N(2) both in pure cultures held at 20 µM dissolved O(2) tension and as endosymbiont of Sesbania rostrata legume nodules, employs a novel, respiratory-membrane endo ...

Inoculation with Azorhizobium caulinodans ORS571 enhances plant growth and salt tolerance of switchgrass (Panicum virgatum L.) seedlings [PDF]
Biotechnology for Biofuels and Bioproducts, 2023 Background Switchgrass (Panicum virgatum L.) is an important biofuel crop that may contribute to replacing petroleum fuels. However, slow seedling growth and soil salinization affect the growth and development of switchgrass.

Control of nitrogen fixation and ammonia excretion in Azorhizobium caulinodans. [PDF]
PLoS Genetics, 2022 Due to the costly energy demands of nitrogen (N) fixation, diazotrophic bacteria have evolved complex regulatory networks that permit expression of the catalyst nitrogenase only under conditions of N starvation, whereas the same condition stimulates ...

The infection and impact of Azorhizobium caulinodans ORS571 on wheat (Triticum aestivum L.). [PDF]
PLoS ONE, 2017 Based on our previous study, cereal crop wheat (Triticum aestivum L.) could be infected by rhizobia Azorhizobium caulinodans ORS571, and form para-nodules with the induction of 2.4-dichlorophenoxyacetic acid, a common plant growth regulator.
