Technical advances in DNA sequencing and manipulation have lead to an explosion in the sequenced universe. However, defining the functions of these remains slow and tedious. Our lab is using mass spectrometry based metabolite profiling to provide direct biochemical datasets to improve our understanding of microbial metabolism. Of particular interest is understanding the distributed and dynamic metabolite networks of environmental microbes and how they transform their environment. These processes underlie all biomes and yet are poorly understood. We are using exometabolomics to directly measure the exogenous metabolic transformations of microbes to gain insights into the coupling of microbial metabolism in microbial communities to create distributed and robust metabolic networks. This understanding will be critical in understanding how to predict and manage microbial communities for long-term sustainability.
