TL;DR: Benthic foraminifers inhabit a wide range of aquatic environments including open marine, brackish, and freshwater environments and Gromia, another taxon also belonging to Rhizaria, accumulate and respire nitrates through denitrification.

TL;DR: The potential rates of nitrate accumulation and oxygen respiration by N. stella were an order of magnitude higher, which seems an adaptation to the infrequent availability of nitrates and oxygen in the sediment surface.

TL;DR: In this paper, the authors performed sequencing of 16S rRNA genes and internal transcribed spacer (ITS) regions, together with detailed morphological analysis of hand-picked individuals of novel non-filamentous as well as known filamentous large sulfur bacteria.

TL;DR: This review article provides an unprecedented overview of nitrate storage and dissimilatory nitrate reduction by diverse marine eukaryotes placed into an eco-physiological context and sketches some evolutionary perspectives of eUKaryotic nitrate metabolism.

TL;DR: Thioploca reduce nitrate to ammonium and the authors found that dinitrogen was not produced, neither through denitrification nor through anammox activity, interpreted as an adaptation to infrequent high sulphate reduction rates in the seabed.
