Dark carbon fixation: an important process in lake sediments. [PDF]
PLoS ONE, 2013 Close to redox boundaries, dark carbon fixation by chemoautotrophic bacteria may be a large contributor to overall carbon fixation. Still, little is known about the relative importance of this process in lake systems, in spite the potentially high ...

Dark Carbon Fixation Measurements in the East Sea (Sea of Japan)
Journal of Marine Science and EngineeringThe vertical distribution patterns of daily primary production and dark carbon fixation were investigated at three stations in the East/Japan Sea (hereafter East Sea), a semi-enclosed marginal sea in the northwest Pacific Ocean.

Ubiquitous Gammaproteobacteria dominate dark carbon fixation in coastal sediments. [PDF]
ISME J, 2016 Marine sediments are the largest carbon sink on earth. Nearly half of dark carbon fixation in the oceans occurs in coastal sediments, but the microorganisms responsible are largely unknown.

Ideas and perspectives: Is dark carbon fixation relevant for oceanic primary production estimates? [PDF]
Biogeosciences, 2019 About half of the global primary production (PP) is generated in the euphotic layer of the ocean. The 14C method developed by Steemann Nielsen (Nielsen, 1952) more than half a century ago has been the most frequently used method to determine PP in all ...

Morphological Plasticity in a Sulfur-Oxidizing Marine Bacterium from the SUP05 Clade Enhances Dark Carbon Fixation [PDF]
mBio, 2019 Sulfur-oxidizing bacteria from the SUP05 clade are abundant in anoxic and oxygenated marine waters that appear to lack reduced sources of sulfur for cell growth.

Four years of climate warming reduced dark carbon fixation in coastal wetlands. [PDF]
ISME JDark carbon fixation (DCF), conducted mainly by chemoautotrophs, contributes greatly to primary production and the global carbon budget. Understanding the response of DCF process to climate warming in coastal wetlands is of great significance for model ...

Chemoautotrophic carbon fixation in thermokarst lakes on the Tibetan Plateau [PDF]
Nature CommunicationsDissolved organic carbon (DOC) derived from thermokarst lakes is usually considered to be prone to microbial degradation and releases substantial carbon dioxide to the atmosphere, potentially enhancing the positive permafrost carbon (C)-climate feedback.

Dark carbon fixation in stream carbon cycling
Limnology and Oceanography, 2023 Headwater streams are often characterized by turbulence, organic matter inputs from terrestrial systems, net heterotrophy, and the microbial loop supplying carbon and energy for consumers.
