AB  - Nitrate is an important nutrient and electron acceptor for microorganisms, having 
      a key role in nitrogen (N) cycling and electron transfer in anoxic sediments. 
      High-nitrate inputs into sediments could have a significant effect on N cycling 
      and its associated microbial processes. However, few studies have been focused on 
      the effect of nitrate addition on the functional diversity, composition, 
      structure and dynamics of sediment microbial communities in contaminated aquatic 
      ecosystems with persistent organic pollutants (POPs). Here we analyzed sediment 
      microbial communities from a field-scale in situ bioremediation site, a creek in 
      Pearl River Delta containing a variety of contaminants including polybrominated 
      diphenyl ethers (PBDEs) and polycyclic aromatic hydrocarbons (PAHs), before and 
      after nitrate injection using a comprehensive functional gene array (GeoChip 
      4.0). Our results showed that the sediment microbial community functional 
      composition and structure were markedly altered, and that functional genes 
      involved in N-, carbon (C)-, sulfur (S)-and phosphorus (P)- cycling processes 
      were highly enriched after nitrate injection, especially those microorganisms 
      with diverse metabolic capabilities, leading to potential in situ bioremediation 
      of the contaminated sediment, such as PBDE and PAH reduction/degradation. This 
      study provides new insights into our understanding of sediment microbial 
      community responses to nitrate addition, suggesting that indigenous 
      microorganisms could be successfully stimulated for in situ bioremediation of 
      POPs in contaminated sediments with nitrate addition.
