In their recent article (Microbial production of recalcitrant dissolved organic matter: long-term
carbon storage in the global ocean. Nature Rev. Microbiol. 8, 593–599 (2010)), Jiao et al. 1 …

The biological pump is a process whereby CO2 in the upper ocean is fixed by primary
producers and transported to the deep ocean as sinking biogenic particles or as dissolved …

Terrestrial carbon sequestration represents an important option for partially mitigating
anthropogenic CO 2 emissions. Evidence suggests that terrestrial ecosystems can be …

Soil microorganisms are central to sustain soil functions and services, like carbon and
nutrient cycling. Currently, we only have a limited understanding of the spatial-temporal …

Microorganisms have a role as gatekeepers for terrestrial carbon fluxes, either causing its
release to the atmosphere through their decomposition activities or preventing its release by …

Studies of the decomposition, transformation and stabilization of soil organic matter (SOM)
have dramatically increased in recent years owing to growing interest in studying the global …

Marine metagenomics is steadily unveiling the phylogenetic diversity and metabolic
potential of the microbial plankton. Our awareness that planktonic Bacteria and Archaea …

The ocean holds a tremendous reservoir of refractory dissolved organic carbon (RDOC) that
plays an important role in carbon cycling and climate change [1]. However, the origin of the …

The ocean has been a regulator of climate change throughout the history of Earth. One key
mechanism is the mediation of the carbon reservoir by refractory dissolved organic carbon …

Soil organic matter is extensively humified; some fractions existing for more than 1000 years.
The soil microbial biomass is surrounded by about 50 times its mass of soil organic matter …
