For more than 100 years it was believed that bacteria were the only group responsible for
the oxidation of ammonia. However, recently, a new strain of archaea bearing a putative …

Anaerobic ammonium-oxidizing (anammox) bacteria are one of the latest additions to the
biogeochemical nitrogen cycle. These bacteria derive their energy for growth from the …

氮的生物地球化学循环主要由微生物驱动, 除固氮作用, 硝化作用, 反硝化作用和氨化作用外,
近年还发现厌氧氨氧化是微生物参与氮循环的一个重要过程. 同时, 随着宏基因组学等分子生物 …

The oxygen minimum zone (OMZ) of the Eastern Tropical South Pacific (ETSP) is 1 of the 3
major regions in the world where oceanic nitrogen is lost in the pelagic realm. The recent …

Primary production in over half of the world's oceans is limited by fixed nitrogen availability.
The main loss term from the fixed nitrogen inventory is the production of dinitrogen gas (N2) …

The pelagic realm of the dark ocean represents a key site for remineralization of organic
matter and long‐term carbon storage and burial in the biosphere. It contains the largest pool …

Marine sponges constitute major parts of coral reefs and deep‐water communities. They
often harbour high amounts of phylogenetically and physiologically diverse microbes, which …

Deposition of marine black shales has commonly been interpreted as having involved a
high level of marine phytoplankton production that promoted high settling rates of organic …

Coastal waters support∼ 90 per cent of global fisheries and are therefore an important food
reserve for our planet. Eutrophication of these waters, due to human activity, leads to severe …

Molecular oxygen (O2) began to accumulate in the atmosphere and surface ocean ca. 2,400
million years ago (Ma), but the persistent oxygenation of water masses throughout the …
