Solid-state NMR Investigation into the Transformation of Necromass to SOM
EMSL Project ID
50153
Abstract
NMR will be utilized to help bridge the knowledge gap between carbon cycling and storage of carbon within soil organic matter (SOM). Specifically, NMR will help address the questions: (1) how much organic carbon enters the soil; (2) where does it enter the soil; (3) what is the composition of the organic matter input; (4) how do plants and microbes influence compounds derived from the each other. To address these questions, the extracellular, intracellular and the insoluble fractions of microbial biomass that we hypothesize will become necromass within soil will be analyzes using NMR. Sub-communities from Michigan and Wisconsin whole soils (GLBRC) have been enriched and cultured in order to to describe the chemical fingerprints of extracellular, intracellular and insoluble fractions of microbial biomass across different bacterial and fungal phylotypes. Molecular signatures of necromass obtained from these cultures will then be looked for within soils.
