TL;DR: Fungal sequences are the most consistently detected eukaryotes in the marine sedimentary subsurface; further, some species may be specifically adapted to the deep subsurfaced and may play important roles in the utilization and recycling of nutrients.

TL;DR: It is shown that for a symbiont-bearing foraminifer, the potential for denitrification resides in the endobionts, and that the allogromiid accumulates nitrate intracellularly, presumably for use inDenitrification.

TL;DR: Foraminifera are known to perform complete denitrification in sediments as mentioned in this paper, but details of this process and the subcellular location of these reactions in foraminifa remain uncertain.

TL;DR: The dinoflagellate was successfully recovered in culture, and morphological analyses have shown that it contains chloroplasts, is gymnodinoid, appears not to have thecal plates, and has an apical groove and sulcal structure that confirm its placement as a relative of the Karenia/Karlodinium group.

TL;DR: A ciliate common in the micro-oxic to anoxic, typically sulfidic, sediments of Santa Barbara Basin (CA, USA) is described, suggesting synergistic metabolisms in this environment.
