Microbial Community Dynamics in Organic-Poor Aquifer Sediments Under Reclaimed Water Incubation
We conducted 120-day anaerobic incubations on two organic-poor sediments from Baoding Plain aquifer, using raw reclaimed water and OM augmentations (20 mg-C/L OM and 200 mg-C/L OM). This examined Fe reduction and As mobilization from reclaimed water infiltration. 16S rRNA amplicon sequencing assessed microbial community changes, focusing on denitrifiers, Fe(III) reducers, and sulfate reducers.
