Calculation and Interpretation of Substrate Assimilation Rates in Microbial Cells Based on Isotopic Composition Data Obtained by nanoSIMS

Frontiers in Microbiology, 2021
Stable isotope probing (SIP) combined with nano-scale secondary ion mass spectrometry (nanoSIMS) is a powerful approach to quantify assimilation rates of elements such as C and N into individual microbial cells.

In situ identification of environmental microorganisms with Raman spectroscopy

Environmental Science and Ecotechnology, 2022
Microorganisms in natural environments are crucial in maintaining the material and energy cycle and the ecological balance of the environment. However, it is challenging to delineate environmental microbes' actual metabolic pathways and intraspecific ...

Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

Advanced Science, Volume 13, Issue 8, 9 February 2026.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...

DNA stable isotope probing on soil treated by plant biostimulation and flooding revealed the bacterial communities involved in PCB degradation

Scientific Reports, 2022
Polychlorinated biphenyl (PCB)-contaminated soils represent a major treat for ecosystems health. Plant biostimulation of autochthonous microbial PCB degraders is a way to restore polluted sites where traditional remediation techniques are not sustainable,

Metagenomic Insights Into the Ecology, Taxonomy and Metabolic Capabilities of ‘Candidatus Darwinibacteriales’ Ord. Nov. (Formerly MBA03), a Potential Key Player in Anaerobic Digestion

Microbial Biotechnology, Volume 18, Issue 12, December 2025.
Metagenomic analysis of anaerobic digesters revealed a dominant, uncultured bacterial taxon—MBA03—now proposed as ‘Candidatus Darwinibacteriales’ ord. nov. This newly defined order includes potential syntrophic acetate‐oxidising bacteria (SAOB), suggesting a key role in methane production.

Resource partitioning between bacteria, fungi and protists in the detritusphere of an agricultural soil

Frontiers in Microbiology, 2016
The flow of plant-derived carbon in soil is a key component of global carbon cycling. Conceptual models of trophic carbon fluxes in soil have assumed separate bacterial and fungal energy channels in the detritusphere, controlled by both substrate ...

Isotopologue Ratios Identify 13C‐Depleted Biomarkers in Environmental Samples Impacted by Methane Turnover

Rapid Communications in Mass Spectrometry, Volume 39, Issue 22, 30 November 2025.
ABSTRACT Rationale The stable carbon isotopic composition (δ13C) of individual lipids is of great value in studying carbon cycling. Among those, microbial lipids in sediments impacted by high methane turnover stand out due to their uniquely depleted isotopic fingerprint.
