Using exometabolomics to predict microbial interactions

In many ecological systems, microorganisms exist in communities. What drives the interactions between these organisms and with their environments is of great interest for predicting the effects that changes to environmental conditions (rainfall, temperature and flora/fauna) will have on soil fertility, green house gas sequestration/release, community structure, etc. I use mass spectrometry based exometabolomics data and total organic carbon analysis to understand how individual microorganisms transform their environments and use this information to predict and test interactions between microorganisms.
