Project description:In response to the issues of low denitrification efficiency and high N₂O emissions in the biological nitrogen removal process of low C/N municipal wastewater, studies typically address these challenges by adding carbon sources. In this study, the addition of microorganisms enhanced the carbon flow and electron transport for nitrate reduction, significantly improving the denitrification performance of low C/N wastewater and reducing N₂O production. Proteomic analysis was employed to explore the mechanisms underlying this effect. The results revealed that the metabolites produced by the added microorganisms, S. oneidensis MR-1 and B. subtilis, including biosurfactants, heme, and cytochromes, altered the intracellular carbon redistribution in P. denitrificans, leading to an increased carbon flow directed towards nitrate reduction, thus enhancing total nitrogen removal efficiency.

Project description:Nitrogen (N) is a key macronutrient required for plant growth, development, and yield. Improving nitrogen use efficiency (NUE) in maize is important for sustainable crop production and reducing fertilizer-associated environmental impacts. To investigate transcriptional responses to nitrate availability, we examined genome-wide gene expression dynamics in maize under nitrate-limiting, and nitrate-recovery conditions. This dataset captures rapid transcriptional shifts in both roots and leaves during nitrate deprivation and subsequent nitrate resupply.
