“…Lotus rhizobia are widely diverse, with over 20 species dispersed amongst several genera (Mesorhizobium, Bradyrhizobium Rhizobium, Ensifer and Aminobacter; Lorite et al, 2018). The study of the Lotus symbiosis has been greatly advanced by the establishment of L. japonicus as a model system for genetic and molecular studies (Tabata and Stougaard, 2014).…”

Biological nitrogen fixation by the Rhizobium-legume symbiosis allows the conversion of atmospheric nitrogen into ammonia within root nodules mediated by the nitrogenase enzyme. Nitrogenase activity results in the evolution of hydrogen as a result of a side reaction intrinsic to the activity of this enzyme. Some rhizobia, and also other nitrogen fixers, induce a NiFe uptake hydrogenase (Hup) to recycle hydrogen produced by nitrogenase, thus improving the efficiency of the nitrogen fixation process. In this work we report the generation and symbiotic behavior of hydrogenase-positive Rhizobium leguminosarum and Mesorhizobium loti strains effective in vetch (Vicia sativa) and birsfoot trefoil (Lotus corniculatus) forage crops, respectively. The ability of hydrogen recycling was transferred to these strains through the incorporation of hup minitransposon TnHB100, thus leading to full recycling of hydrogen in nodules. Inoculation of Vicia and Lotus plants with these engineered strains led to significant increases in the levels of nitrogen incorporated into the host legumes. The level of improvement of symbiotic performance was dependent on the recipient strain and also on the legume host. These results indicate that hydrogen recycling has the potential to improve symbiotic nitrogen fixation in forage plants.

In this study, we investigated the feasibility of electrode-assisted ammonia oxidation and subsequent nitrite accumulation within an anaerobic microbial fuel cell (MFC). Our study focused on determining whether these processes could be effectively maintained in a strictly anaerobic environment, which would be critical for advancing nitrogen removal technologies in wastewater treatment. Although we demonstrated electrode-assisted ammonia oxidation and nitrite accumulation, the expected dominance of these reactions within the system was not achieved. In contrast, ammonia assimilation appeared to be the prevailing nitrogen removal pathway under our experimental conditions. The study did not identify the specific microbial communities responsible for these processes, however, illustrates an important area for future research. Our findings enhance the current understanding of nitrogen cycling in anaerobic MFCs and demonstrate the need for improved strategies to enrich nitrifying bacteria and optimize electrode-assisted nitrogen removal processes in wastewater treatment.
