Effects of estuarine sediment hypoxia on nitrogen fluxes and ammonia oxidizer gene transcription

GCJ Abell, J Banks, DJ Ross, JP Keane… - FEMS microbiology …, 2011 - academic.oup.com
The effects of sediment hypoxia, resulting from increased carbon loads or decreased
dissolved oxygen (DO), on nitrogen cycling in estuarine environments is poorly understood.
The important role played by bacterial and archaeal ammonia oxidizers in the eventual
removal of nitrogen from estuarine environments is likely to be strongly affected by hypoxic
events. In this study, an analysis of the effects of different levels of sediment hypoxia (5%,
20% and 75% DO) was performed in a microcosm experiment. Changes in the nutrient …
