title: Stable carbon isotopes of lipid biomarkers: analysis of metabolites and metabolic fates of environmental microorganisms.
abstract: Lipid biomarkers are specific compounds that are characteristic of certain groups or species of microorganisms. The use of natural or labeled carbon isotopes of lipid biomarkers has enabled a better understanding of carbon flow pathways at the molecular level. Recent advances include, but are not limited to, the elucidation of mechanisms of anaerobic methane oxidation mediated by syntrophic sulfate-reducing bacteria and Archaea, linking microbial populations with specific microbial processes or bacterial transport mechanisms in natural or contaminated environments, and elucidation of the biosynthetic pathways of cellular material.
