Project description:Anaerobic digestion (AD) is a core technology in management of urban organic wastes, converting a fraction of the organic carbon to methane and the residual digestate, the biorest, have a great potential to become a major organic fertilizer for agricultural soils in the future. At the same time, mitigation of N2O-emissions from the agricultural soils is needed to reduce the climate forcing by food production. Our goal was therefore to enrich for N2O reducing bacteria in AD digestates prior to fertilization, and in this way provide an avenue for large-scale and low-cost cultivation of strongly N2O reducing bacteria which can be directly introduced to agricultural soils in large enough volumes to alter the fate of nitrogen in the soils. Gas kinetics and meta-omics (metagenomics and metaproteomics) analyses of the N2O enriched digestates identified populations of N2O respiring organisms that grew by harvesting fermentation intermediates of the methanogenic consortium.
Project description:Previous experiments have demonstrated that c-Maf can undergo liquid-liquid phase separation (LLPS) in MM. In order to search for the downstream target genes of c-Maf based on its LLPS regulation, we successfully constructed three kinds of cells with EV, c-Maf and already c-Maf-IDR mutation, and simultaneously subjected the three kinds of cells to ChIP sequencing (selecting the FLAG-tagged antibody), and then analysed them for the differential genes, thus screening the downstream targets of c-Maf based on its LLPS regulation.
