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 ...

MetabolomicsUntargeted LC–MS metabolomics of Chlorella vulgaris under different carbon-source conditions

This study presents untargeted LC–MS/MS metabolomics and lipidomics datasets comparing CON and MAL experimental groups acquired in both positive and negative electrospray ionization modes. For quality control, a pooled QC sample was prepared by mixing equal volumes of all study samples and was an...

MetabolomicsMetabolic Response of a Chemolithoautotrophic Archaeon to Carbon Limitation

The ubiquitously distributed ammonia-oxidizing archaea generate energy from ammonia and build cell mass from inorganic carbon sources, thereby contributing to both the global nitrogen and carbon cycles. However, little is known about the regulation of their predicted core carbon metabolism. A the...

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...

MetabolomicsRegulatory mechanisms for aromatic carbon metabolism in Comamonas testosteroni
Widely reported discrepancies between metabolic flux and transcripts or enzyme levels in bacterial metabolism imply complex regulation mechanisms need to be considered, especially in new bacterial platforms for bioremediation and bioproduction. Comamonas testosteroni strains, which metabolize variou...

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...

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...

MetabolomicsAn obligate aerobe adapts to hypoxia by hybridising fermentation with carbon storage
In soil ecosystems, obligately aerobic bacteria survive oxygen deprivation (hypoxia) by entering non-replicative persistent states. Little is known about how these bacteria rewire their metabolism to stay viable during persistence. The model obligate aerobe Mycobacterium smegmatis maintains redox ho...
