Origin and temporal variability of unusually low δ13C-DOC values in two High Arctic catchments [PDF]

, 2016
The stable carbon isotopic composition of dissolved organic matter (δ13C-DOC) reveals information about its source and extent of biological processing. Here we report the lowest δ13C-DOC values (−43.8‰) measured to date in surface waters.

The Effect of Nitrogen Enrichment on C1-Cycling Microorganisms and Methane Flux in Salt Marsh Sediments

Frontiers in Microbiology, 2012
Methane (CH4) flux from ecosystems is driven by C1-cycling microorganisms – the methanogens and the methylotrophs. Little is understood about what regulates these communities, complicating predictions about how global change drivers such as nitrogen ...

Methanotrophy potential versus methane supply by pore water diffusion in peatlands [PDF]

, 2008
International audienceLow affinity methanotrophic bacteria consume a significant quantity of methane in wetland soils in the vicinity of plant roots and at the oxic-anoxic interface.

Direct amplification of nodD from community DNA reveals the genetic diversity of Rhizobium leguminosarum in soil [PDF]

, 2001
Sequences of nodD, a gene found only in rhizobia, were amplified from total community DNA isolated from a pasture soil. The polymerase chain reaction (PCR) primers used, Y5 and Y6, match nodD from Rhizobium leguminosarum biovar trifolii, R. leguminosarum

Microbial and chemical predictors of methane release from a stratified thermokarst permafrost hotspot

Frontiers in Microbiology
Soils are dynamic interfaces that can act as both sources and sinks of methane (CH₄), yet the microbial processes underlying these fluxes remain poorly constrained in current Earth system models—particularly in thawing permafrost regions.

Survival strategies for the microbiome in a vent-dwelling glass sponge from the middle Okinawa Trough

Frontiers in Microbiology
The adaptive mechanisms of sponge microbiomes to harsh deep-sea environments, including hydrothermal vents and cold seeps, remain unclear. Here, we used metagenomics to investigate the microbiome of an undescribed vent-dwelling glass sponge from the ...

Dating the cyanobacterial ancestor of the chloroplast [PDF]

, 2009
Cyanobacteria have played a pivotal role in the history of life on Earth being the first organism to carry out oxygenic photosynthesis, which changed atmospheric chemistry and allowed the evolution of Eukarya.

Climate change induces shifts in coastal Baltic Sea surface water microorganism stress and photosynthesis gene expression

Frontiers in Microbiology
The world’s oceans are challenged by climate change linked warming with typically highly populated coastal areas being particularly susceptible to these effects.

A biochemical framework for anaerobic oxidation of methane driven by Fe(III)-dependent respiration

Nature Communications, 2018
The unavailability of pure cultures has prevented a mechanistic understanding of anaerobic methanotrophy. Here the authors report a biochemical investigation of Methanosarcina acetivorans that supports a pathway anchored by Fe(III)-dependent mechanisms ...
