MetabolomicsExometabolomic profiling of bacterial strains cultivated using Arabidopsis root extract as the sole carbon source
The ability of microorganisms to use root-derived metabolites as growth substrates is a key trait for success in the rhizospheric niche. However, few studies describe which specific metabolites are consumed, or to what degree microbial strains differ in their substrate consumption patterns. Here we ...

MetabolomicsHierarchical Carbon Metabolism in Iron-Deficient Bacteria Favors Iron-Scavenging Strategy

High-affinity iron (Fe) scavenging compounds, or siderophores, are widely employed by soil bacteria to survive scarcity in bioavailable Fe. Siderophore biosynthesis relies on cellular carbon metabolism, despite reported decrease in both carbon uptake and Fe-containing metabolic proteins in Fe-def...

TranscriptomicsThe yeast osmostress response is carbon source dependent
Adaptation to altered osmotic conditions is a fundamental property of living cells and has been studied in particular detail in the yeast Saccharomyces cerevisiae. Yeast cells accumulate glycerol as compatible solute, controlled at different levels by the High Osmolarity Glycerol (HOG) response path...

MetabolomicsNucleotide depletion signals early-stage soil stable carbon collapse in anthropogenically disturbed alpine ecosystems
Anthropogenic disturbances are a primary cause of soil organic carbon (SOC) destabilization in alpine ecosystems. However, effective management is hindered by a """"response delay"""" of macro metrics used to characterize stable carbon pools (e.g., microbial necromass carbon and aggregate associated...

MetabolomicsCharacterization of Phytoplankton-Excreted Metabolites Mediating Carbon Flux through the Surface Ocean

The marine labile dissolved organic carbon (DOC) pool is a dynamic reservoir of thousands of molecules. After excretion or release by phytoplankton and other microbes, metabolites are rapidly consumed, resulting in very low standing concentrations (picomolar to low nanomolar). To date, marine phy...

MetabolomicsUnlocking soil carbon potential in giant panda habitat

Forest management in giant panda habitats necessitates strategies that simultaneously support biodiversity and ecosystem carbon sequestration. Here, we demonstrate that protecting understory vegetation is indispensable for sustaining the soil carbon sink in restored subalpine coniferous plantatio...

MetabolomicsPhotorespiration is linked to DNA methylation by formate as one-carbon source.
DNA methylation is a key epigenetic modification regulating genome organization, stability, and gene expression. Stable DNA methylation critically relies on methyl groups provided through folate-mediated one-carbon (C1) metabolism, yet the origin and regulation of C1 supply remain elusive. Here we d...

TranscriptomicsA comparative systems analysis of polysaccharide-elicited responses in Neurospora crassa reveals carbon source-specific cellular adaptations
Filamentous fungi are powerful producers of hydrolytic enzymes for the deconstruction of plant cell wall polysaccharides. However, the central question of how these sugars are perceived in the context of the complex cell wall matrix remains largely elusive. To address this question in a systematic f...

MetabolomicsCarbon starvation enhances microbiologically influenced corrosion in marine offshore infrastructures
an exploratory mechanistic Q17 A study to investigate how carbon availability influences microbial community structure and corrosion behavior in multispecies biofilms relevant to offshore infrastructure. Sediment from the North Sea was used as inoculum, and steel coupons were exposed under blank (no...

TranscriptomicsTranscription profiling of S. cerevisiae grown in acetate, ethanol and maltose limited conditions to investigate transcriptional regulation in controlling fluxes in central carbon metabolism
In contrast to batch cultivation, chemostat cultivation allows the identification of carbon source responses without interference by carbon-catabolite repression, accumulation of toxic products, and differences in specific growth rate. This study focuses on the yeast Saccharomyces cerevisiae, grown ...
