16S rRNA gene amplicon sequencing of granular sludge microbial communities during mature landfill leachate treatment under different biodegradable COD/TN ratios
This study characterized changes in the microbial community of a granular sludge reactor treating mature landfill leachate across five operational stages with different biodegradable chemical oxygen demand-to-total nitrogen ratios. Granular sludge samples were collected from the reactor during stages S1-S5. The V4 region of the 16S rRNA gene was analyzed using paired-end Illumina amplicon sequencing. These data support the investigation of microbial community succession associated with dissolved organic nitrogen removal and nitrogen transformation during reactor operation.
