Microbial activity is key in understanding the contribution of microbial communities to ecosystem functions. Metabolic labelling with heavy water (D2 O) leads to the formation of carbon-deuterium bonds in active microorganisms. We illustrated how D2 O labelling allows monitoring of metabolic activity combined with a functional characterization of active populations in complex microbial communities. First, we demonstrated by single cell Raman microspectroscopy that all measured bacterial cells…

Bacterial Necromass Is Rapidly Metabolized by Heterotrophic Bacteria and Supports Multiple Trophic Levels of the Groundwater Microbiome
Subsurface microbiomes provide essential ecosystem services, like the generation of drinking water. These ecosystems are devoid of light-driven primary production, and microbial life is adapted to
Divergent microbial communities in groundwater and overlying soils exhibit functional redundancy for plant-polysaccharide degradation
The degradation of plant-derived polysaccharides in groundwater is driven by organisms completely distinct from those active in soil, and the involvement of members of the candidate phyla Cand.
Influence of Carbon Sources on Quantification of Deuterium Incorporation in Heterotrophic Bacteria: A Raman-Stable Isotope Labeling Approach.
The Raman-D2O approach, when coupled with chemometrics, constitutes a powerful approach for monitoring single bacterial cells and shows that compared to complex carbon substrates, the deuterium assimilation is higher in presence of simpler substrates such as sugars but differs significantly among bacterial isolates.
Phenotypic Differentiation of Autotrophic and Heterotrophic Bacterial Cells Using Raman-D2O Labeling.
Carbon cycling is one of the major biogeochemical processes driven by bacteria. Autotrophic bacteria convert carbon dioxide (CO2) into organic compounds that are used by heterotrophs. Mixotrophic
SIP-Metaproteomics: Linking Microbial Taxonomy, Function, and Activity.
Protocols for obtaining isotopically labeled proteins and for downstream SIP-metaproteomics analysis are provided for the detection and characterization of active key species in microbial populations under near-natural conditions.
Rates of primary production in groundwater rival those in oligotrophic marine systems
Using a novel ultra-low level 14C-labeling technique, it is shown that in situ carbon fixation rates in a carbonate aquifer reached 10% of the median rates measured in oligotrophic marine surface waters, and were up to six-fold greater than those observed in lower euphotic zone waters where deep chlorophyll levels peak.
Substrate-dependent incorporation of carbon and hydrogen for lipid biosynthesis by Methanosarcina barkeri.
The variable DIC and water H incorporation into M. barkeri lipids imply systematic, metabolic patterns of isotope incorporation and suggest that the ratio of 13 C-DIC vs D2 O assimilation in environmental samples may serve as a proxy for microbial energetics in addition to microbial production and carbon assimilation pathways.
Impact of hydrologic boundaries on microbial planktonic and biofilm communities in shallow terrestrial subsurface environments
It is suggested that merging traditional activity measurements and sequencing/-omics technologies with hydrological parameters important to sediment biofilm assembly and stability will help delineate key system parameters and enhance the understanding of shallow subsurface ecophysiology in terms of bulk-flow through porous media.


Functional diversity of microbial communities in pristine aquifers inferred by PLFA- and sequencing-based approaches
The relative abundances of phospholipid-derived fatty acids were used to link specific biochemical markers within the microbial communities to the spatio-temporal changes of the groundwater physico-chemistry, demonstrating the power of complementary information derived from PLFA-based and sequencing-based approaches.
Tracking heavy water (D2O) incorporation for identifying and sorting active microbial cells
A new technique that allows fast and nondestructive activity measurements of microbial communities on a single-cell level in complex samples using stable isotope probing with heavy water (D2O) combined with Raman microspectroscopy is developed.
Stable-isotope probing implicates Methylophaga spp and novel Gammaproteobacteria in marine methanol and methylamine metabolism
Predominant DGGE phylotypes, 16S rRNA, methanol and methylamine dehydrogenase gene sequences, and cultured isolates all implicated Methylophaga spp, moderately halophilic marine methylotrophs, in the consumption of both methnol and methamphetamine in coastal sea water.
Assessing sub-seafloor microbial activity by combined stable isotope probing with deuterated water and 13C-bicarbonate.
In anoxic sediments from a Swedish fjord, it was found that > 99% of newly formed lipids were attributed to predominantly heterotrophic bacteria, indicating that the factors controlling the presence of these two lipid groups must differ fundamentally.
(15)N- and (2)H proteomic stable isotope probing links nitrogen flow to archaeal heterotrophic activity.
The nearly exclusive ability of Archaea to synthesize proteins using ( 2)H2O may be due to archaeal heterotrophy, whereby Archaea offset deleterious effects of (2)H by accessing (1)H generated by respiration of organic compounds.
Metabolic responses of novel cellulolytic and saccharolytic agricultural soil Bacteria to oxygen.
A large uncultured diversity of soil Bacteria was involved in the utilization of cellulose and products of its hydrolysis, and oxygen availability impacted differentially on the activity of taxa and different redox guilds (e.g. fermenters and iron reducers) compete or interact during cellulose degradation in aerated soils.
Reverse and Multiple Stable Isotope Probing to Study Bacterial Metabolism and Interactions at the Single Cell Level.
A novel Raman stable isotope probing (Raman-SIP), which uses Raman microspectroscopy coupled with reverse and D2O colabeling to study metabolic interactions in a two-species community consisting of Acinetobacter baylyi ADP1 and Escherichia coli DH5α-GFP, is developed.
Large Fractions of CO2-Fixing Microorganisms in Pristine Limestone Aquifers Appear To Be Involved in the Oxidation of Reduced Sulfur and Nitrogen Compounds
The results indicate that a large fraction of bacteria in pristine limestone aquifers has the genetic potential for autotrophic CO2 fixation, with energy most likely provided by the oxidation of reduced sulfur and nitrogen compounds.
