Project Abstract
A major component of soil-organic-matter (SOM) is microbially derived and molecularly uncharacterised. Knowledge of SOM transitions is vital to understanding carbon cycling agricultural practice implications Irelands carbon trading responsibilities interactions with anthropogenic chemicals and novel compound potential. In this study we propose to advance structural understanding of the microbial component of SOM. This will be accomplished by growing 13C and 15N isotopically enriched soil microbial biomass. Isotopic enrichment greatly enhances NMR sensitivity. Advanced multi-dimensional NMR GC-MS and HPLC methods will be applied for the first time to study these complex mixtures and influence of this CO2 sink on natural processes.
