Bacterial community profiles in a bioreduced uranium contaminated site after reoxidation

A site contaminated with uranium was bioreduced through multiple injections of ethanol to immobilize the uranium in situ. Then it was allowed to reoxidize via the invasion of low-pH , high-nitrate groundwater back into the reduced zone for about 4 years. To examine the biogeochemical response, high-throughput sequencing were applied to characterize bacterial population shifts.
