Dilution solves the recalcitrance question The deep ocean is full of dissolved organic carbon, some of which has remained unchanged for thousands of years. What makes these compounds so resistant to microbial degradation? Perhaps their chemical structures make them intrinsically difficult to metabolize? In contrast, Arrieta et al. show that they are simply too dilute to be viable sources of energy for microorganisms (see the Perspective by Middleburg). Further experiments show that if these… 

Rapid microbial diversification of dissolved organic matter in oceanic surface waters leads to carbon sequestration

This work provides direct experimental evidence showing that within hours of labile DOM release, its breakdown and recombination with ambient DOM leads to the formation of a diverse array of new molecules in oligotrophic North Atlantic surface waters.

Escape by dilution

It is shown that dissolved organic matter in much of the deep ocean is too dilute to be consumed by microbes, and underutilization of resources in nutrient-low surface waters does not apply to the nutrient-rich deep sea.

Mixing it up in the ocean carbon cycle and the removal of refractory dissolved organic carbon

The results suggest that while refractory molecules can persist in the ocean for millennia, removal is rapid when they encounter their fate, and the observed and projected climate-induced slowdown of global overturning circulation could reduce the exposure of refraction molecules to disparate removal processes.

Molecular properties are a primary control on the microbial utilization of dissolved organic matter in the ocean

The global ocean sequesters a large amount of reduced carbon in dissolved organic molecules that can persist for centuries to millennia. The persistence of dissolved organic carbon (DOC) in the deep

Long-term stability of marine dissolved organic carbon emerges from a neutral network of compounds and microbes

It is concluded that while structurally-recalcitrant molecules exist, they are not required in the model to explain either the amount or longevity of DOC.

Limited utilization of extracted dissolved organic matter by prokaryotic communities from the subtropical North Atlantic

The ocean contains a large reservoir of dissolved organic matter (DOM) that persists for millennia. Both the very dilute concentrations of individual DOM molecules and intrinsic recalcitrance to

What Is Refractory Organic Matter in the Ocean?

About 20% of the organic carbon produced in the sunlit surface ocean is transported into the ocean’s interior as dissolved, suspended and sinking particles to be mineralized and sequestered as

Large Stimulation of Recalcitrant Dissolved Organic Carbon Degradation by Increasing Ocean Temperatures

More than 96% of organic carbon in the ocean is in the dissolved form, most of it with lifetimes of decades to millennia. Yet, we know very little about the temperature sensitivity of dissolved

Contribution of structural recalcitrance to the formation of the deep oceanic dissolved organic carbon reservoir

The results suggest that the recalcitrance of RDOC is largely related to its chemical properties, whereas dilution plays a minor role in determining the persistence of deep-ocean DOC.

Microbial Physiology Governs the Oceanic Distribution of Dissolved Organic Carbon in a Scenario of Equal Degradability

Dissolved organic carbon (DOC) forms one of the largest active organic carbon reservoirs on Earth and reaches average radiocarbon ages of several thousand years. Many previous large scale DOC models

Results suggest that microbial processes alter the molecular structure of DOM, making it resistant to further degradation and thereby preserving fixed carbon in the ocean.
