We demonstrate the synthesis of NH3 from N2 and H2O at ambient conditions in a single reactor by coupling hydrogen generation from catalytic water splitting to a H2-oxidizing bacterium Xanthobacter autotrophicus, which performs N2 and CO2 reduction to solid biomass. Living cells of X. autotrophicus may be directly applied as a biofertilizer to improve growth of radishes, a model crop plant, by ...

Sand culture using radish (Raphanus sativus L.) and hydroponics using carrot (Daucus carota L.) were conducted to examine root-uptake of carbon and its assimilation in the form of 14C-acetic acid. 14C-acetic acid (1, 2-14C, radioactivity: 74 kBq) was added to each pot. Radishes were grown under the dark conditions or the light conditions for 24 h. Carrot were grown under the light conditions af...

Our current understanding suggests that nutrient management strategies applied to agricultural soils over multiple years are required cause major and stable shifts in soil microbial communities. However, some studies suggest can benefit even from sporadic, single additions of organic matter. Here we investigate how high-quality matter significant communities cropping cycles. We grew radishes a ...
