partial denitrification anammox Raw sequence reads

The aim of this study was to examine the BNR capabilities of a PDA system, inoculated with biofilm carriers previously performing PNA. The effect on the PDA process when using either acetate or propionate as carbon source for the denitrification was investigated by operating two continuous lab-scale reactors in parallel. The stability of the systems was de-termined by operating the reactors for ten weeks including start-up. Furthermore, ex-situ activ-ity batch tests were performed regularly to evaluate the PDA capabilities of the microbial pop-ulations on the carriers. And metagenomic sequencing was performed to investigate the microbial structure and functional potential of the enriched biofilms on carriers.
