Soil Carbon Saturation: What Do We Really Know?

Global Change Biology, Volume 31, Issue 5, May 2025.
Managing soils to increase organic carbon presents a potential opportunity to mitigate and adapt to global change challenges. However, soils differ widely in their biophysical limits for carbon accumulation, and knowledge of these limits may aid in targeted management initiatives.

Proteomic stable isotope probing with an upgraded Sipros algorithm for improved identification and quantification of isotopically labeled proteins

Microbiome
Background Proteomic stable isotope probing (SIP) is used in microbial ecology to trace a non-radioactive isotope from a labeled substrate into de novo synthesized proteins in specific populations that are actively assimilating and metabolizing the ...

DNA- and RNA-SIP Reveal Nitrospira spp. as Key Drivers of Nitrification in Groundwater-Fed Biofilters

mBio, 2019
Nitrification, the oxidative process converting ammonia to nitrite and nitrate, is driven by microbes and plays a central role in the global nitrogen cycle.

Transcriptome-Stable Isotope Probing Provides Targeted Functional and Taxonomic Insights Into Microaerobic Pollutant-Degrading Aquifer Microbiota

Frontiers in Microbiology, 2018
While most studies using RNA-stable isotope probing (SIP) to date have focused on ribosomal RNA, the detection of 13C-labeled mRNA has rarely been demonstrated.

Stable Isotope and Metagenomic Profiling of a Methanogenic Naphthalene-Degrading Enrichment Culture

Microorganisms, 2018
Polycyclic aromatic hydrocarbons (PAH) such as naphthalene are widespread, recalcitrant pollutants in anoxic and methanogenic environments. A mechanism catalyzing PAH activation under methanogenic conditions has yet to be discovered, and the microbial ...

Detection of autotrophic verrucomicrobial methanotrophs in a geothermal environment using stable isotope probing

Frontiers in Microbiology, 2012
Genomic analysis of the methanotrophic verrucomicrobium Methylacidiphilum infernorum strain V4 has shown that most pathways conferring its methanotrophic lifestyle are similar to those found in proteobacterial methanotrophs.

Physiological versatility of ANME-1 and Bathyarchaeotoa-8 archaea evidenced by inverse stable isotope labeling

Microbiome
Background The trophic strategy is one key principle to categorize microbial lifestyles, by broadly classifying microorganisms based on the combination of their preferred carbon sources, electron sources, and electron sinks.

Asymbiotic biological nitrogen fixation makes a great contribution to nitrogen balance in unfertilized alpine grasslands across the Qinghai-Tibet Plateau

Journal of Integrative Agriculture
Nitrogen limitation has been well documented in grasslands on the Qinghai-Tibet Plateau (QTP), significantly affecting predictions of plant growth and carbon sequestration potential under future climate change scenario.
