Syntrophic interspecies electron transfer drives carbon fixation and growth by Rhodopseudomonas palustris under dark, anoxic conditions

Science Advances, 2021
Electrosyntrophy drives anoxygenic photosynthetic bacteria to fix CO2 in the dark. In natural anoxic environments, anoxygenic photosynthetic bacteria fix CO2 by photoheterotrophy, photoautotrophy, or syntrophic anaerobic photosynthesis. Here, we describe

Biocrust carbon exchange varies with crust type and time on Chihuahuan Desert gypsum soils

Frontiers in Microbiology, 2023
IntroductionIn dryland systems, biological soil crusts (biocrusts) can occupy large areas of plant interspaces, where they fix carbon following rain. Although distinct biocrust types contain different dominant photoautotrophs, few studies to date have ...

The Predominance of Ammonia-Oxidizing Archaea in an Oceanic Microbial Community Amended with Cyanobacterial Lysate

Microbiology Spectrum, 2023
When the oligotrophic microbial community was amended with Synechococcus-derived dissolved organic matter (SDOM) and incubated under the dark condition, archaea relative abundance was initially very low but made up more than 60% of the prokaryotic ...

Composition and Ecological Roles of the Core Microbiome along the Abyssal-Hadal Transition Zone Sediments of the Mariana Trench

Microbiology Spectrum, 2022
The unique geological features of hadal trenches are known to influence both the structure and ecological function of microbial communities. It is also well known that heterotrophs and chemoautotrophs dominate the hadal and abyssal pelagic zones ...

Enhanced Dark Carbon Dioxide Fixation in Maize [PDF]

Plant Physiology, 1979
The enhanced dark CO(2) uptake after a preillumination period under varying O(2) concentrations has been measured with maize, a C(4) plant. For comparison the same study has been conducted with tomato, a C(3) plant. Increasing the O(2) concentration during preillumination inhibits by 70% the subsequent dark CO(2) uptake in tomato but stimulates 2-fold ...

Free atmospheric CO2 enrichment increased above ground biomass but did not affect symbiotic N2-fixation and soil carbon dynamics in a mixed deciduous stand in Wales [PDF]

, 2011
Through increases in net primary production (NPP), elevated CO2 is hypothesizes to increase the amount of plant litter entering the soil. The fate of this extra carbon on the forest floor or in mineral soil is currently not clear.

Relevance of Nutrient-Limited Phytoplankton Production and Its Bacterial Remineralization for Carbon and Oxygen Fluxes in the Baltic Sea

Frontiers in Marine Science, 2019
The Baltic Sea is prone to oxygen deficiency due to the restricted water exchange with the North Sea in coincidence with a high biological oxygen demand.

Heterotrophic Carbon Fixation in a Salamander-Alga Symbiosis

Frontiers in Microbiology, 2020
The unique symbiosis between a vertebrate salamander, Ambystoma maculatum, and unicellular green alga, Oophila amblystomatis, involves multiple modes of interaction. These include an ectosymbiotic interaction where the alga colonizes the egg capsule, and

Deoxygenation enhances photosynthetic performance and increases N2 fixation in the marine cyanobacterium Trichodesmium under elevated pCO2

Frontiers in Microbiology, 2023
Effects of changed levels of dissolved O2 and CO2 on marine primary producers are of general concern with respect to ecological effects of ongoing ocean deoxygenation and acidification as well as upwelled seawaters.
