Purvine1 1Environmental Molecular Sciences Laboratory, Pacific Northwest National Laboratory, 2Department of Soil, Water and Environmental Science, University of Arizona, 3Department of Earth Ocean and Atmospheric Sciences, Florida State University, 4Bruker Daltonics Inc., 5Biological Sciences Division, Pacific Northwest National Laboratory This protocol describes a single throughput for complementary analytical and omics techniques culminating in a fully-paired characterization of natural organic matter and microbial proteomics in different ecosystems. This approach permits robust comparisons for identifying metabolic pathways and transformations important for describing greenhouse gas production and predicting responses to environmental change.
