- Abstract:
- The aim of this pilot project is to exploit the combined use of compound-specific radiocarbon analysis and phospholipid fatty acid (PLFA) profiling approaches to investigate the extent of utilisation of sequestered or 'old' carbon by micro-organisms. The rationale for this proposal is that the radiocarbon age of individual microbial PLFAs will reflect the radiocarbon ages of the carbon sources utilised by the source micro-organism. Compound-specific radiocarbon determinations by accelerator mass spectrometry (AMS) of individual PLFAs isolated from soils extracts by preparative gas chromatography (PGC) will allow the degree of utilisation of 'new' and 'old' carbon in soils and peats by the microbial biomass to be assessed. PLFA profiling and structural investigations will allow the classes of consumer micro-organisms to be identified.
