Microbial nitrite oxidation is the primary pathway that generates nitrate in wastewater
treatment systems and can be performed by a variety of microbes: namely, nitrite-oxidizing …

Dysoxic marine waters (DMW,< 1 μM oxygen) are currently expanding in volume in the
oceans, which has biogeochemical, ecological and societal consequences on a global …

The microbial community composition and biogeochemical dynamics of coastal permeable
(sand) sediments differs from cohesive (mud) sediments. Tide-and wave-driven …

Nitrospirales, including the genus Nitrospira, are environmentally widespread
chemolithoautotrophic nitrite-oxidizing bacteria. These mostly uncultured microorganisms …

Chemosynthesis is a metabolic process that transfers carbon to the biosphere using
reduced compounds. It is well recognised that chemosynthesis occurs in much of the ocean …

Ammonia-oxidising archaea of the phylum Thaumarchaeota are important organisms in the
nitrogen cycle, but the mechanisms driving their radiation into diverse ecosystems remain …

Stable isotope labeling of microbial taxa of interest and their sorting provide an efficient and
direct way to answer the question “who does what?” in complex microbial communities …

Background Ferromanganese nodule-bearing deep-sea sediments cover vast areas of the
ocean floor, representing a distinctive habitat in the abyss. These sediments harbor unique …

Throughout coastal Antarctica, ice shelves separate oceanic waters from sunlight by
hundreds of meters of ice. Historical studies have detected activity of nitrifying …

Paddy fields are one of the most important sources of nitrous oxide (N2O), but
biogeochemical N2O production mechanisms in the soil profile remain unclear. Our study …
