Beyond Archaea: The Table Salt Bacteriome
Frontiers in Microbiology, 2021 Commercial table salt is a condiment with food preservative properties by decreasing water activity and increasing osmotic pressure. Salt is also a source of halophilic bacteria and archaea.

Tracking Microbial Evolution in the Subseafloor Biosphere
mSystems, 2021 The deep marine subsurface constitutes a massive biosphere that hosts a multitude of archaea, bacteria, and viruses across a diversity of habitats. These microbes play key roles in mediating global biogeochemical cycles, and the marine subsurface is ...

Hydroxylamine as an intermediate in ammonia oxidation by globally abundant marine archaea [PDF]
Proceedings of the National Academy of Sciences, 2012 The ammonia-oxidizing archaea have recently been recognized as a significant component of many microbial communities in the biosphere. Although the overall stoichiometry of archaeal chemoautotrophic growth via ammonia (NH 3 ) oxidation to nitrite (NO 2 −

Diel Patterns in the Composition and Activity of Planktonic Microbes in a Subtropical Bay
Ocean-Land-Atmosphere ResearchPlanktonic microbes play a crucial role in the matter transformation and energy transfer of marine ecosystems. Marine microbial communities are profoundly influenced by various environmental factors, and their variations are typically investigated in a ...

Marine archaea take a short cut in the nitrogen cycle [PDF]
Proceedings of the National Academy of Sciences, 2012 Seeing “nitrification” and “Archaea” in the title of the paper in PNAS by Alonso-Saez et al. (1) will not surprise anyone following the story about the role of these microbes in an important pathway of the nitrogen cycle. What will puzzle, if not surprise, everyone is the other key word, “urea.” That nitrogenous compound never comes up in discussions ...

Advanced Science, EarlyView.An STI‐guided metagenomic association framework links soybean salt‐tolerance phenotypes with rhizosphere microbiome composition and network organization in natural saline soils. The approach identifies candidate beneficial taxa, including Thalassospira xiamenensis, and provides an efficient strategy for mining stress‐protective microbes from native ...
