The microbial carbon pump and climate change
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 …

Experimental insight into the enigmatic persistence of marine refractory dissolved organic matter
X Zheng, R Cai, H Yao, X Zhuo, C He… - Environmental …, 2022 - ACS Publications
More than 90% of marine dissolved organic matter (DOM) is biologically recalcitrant. This
recalcitrance has been attributed to intrinsically refractory molecules or to low concentrations …

Deep ocean microbial communities produce more stable dissolved organic matter through the succession of rare prokaryotes
The microbial carbon pump (MCP) hypothesis suggests that successive transformation of
labile dissolved organic carbon (DOC) by prokaryotes produces refractory DOC (RDOC) and …

Oxidative metabolisms catalyzed Earth's oxygenation
The burial of organic carbon, which prevents its remineralization via oxygen-consuming
processes, is considered one of the causes of Earth's oxygenation. Yet, higher levels of …

Long-term photochemical and microbial alterations lead to the compositional convergence of algal and terrestrial dissolved organic matter
Lakes are expected to become more active in processing dissolved organic matter (DOM),
but the fate of DOM with different origins remains poorly constrained. We conducted long …
