Nitrifier Gene Abundance and Diversity in Sediments Impacted by Acid Mine Drainage
Frontiers in Microbiology, 2017 Extremely acidic and metal-rich acid mine drainage (AMD) waters can have severe toxicological effects on aquatic ecosystems. AMD has been shown to completely halt nitrification, which plays an important role in transferring nitrogen to higher organisms ...

Marine Sponges as Bioindicators of Nitrogen within Estuaries on the Oregon Coast [PDF]
, 2012 As filter feeders, sponges are highly integrated with their environment. Many sponges also host diverse communities of bacteria, including many that are hypothesized to carry out a variety of nitrogen transformations. The presence of these bacteria makes
