BN23B:
Organic Matter-Microbe Interactions: Underlying Links and Constraints I


Session ID#: 37682

Session Description:
From dissolved molecules to colloids and particulates, organic matter provides the energetic foundation for heterotrophic microorganisms in freshwater and marine environments. The complex interactions involved in this substrate-consumer relationship have long been reduced to simple box-arrow models, in which both microbe and organic matter compartments are treated as “black boxes” linked by simplified mutual connections. We now begin to open these “black boxes” and intend to understand the connections between molecules and organisms through the application of emerging analytical techniques that provide information on organic matter composition and microbial communities in unsurpassed detail. At the same time, novel experimental approaches and visualization techniques reveal physical constraints and abiotic processes that influence the occurrence and pace of organic matter-microbe interactions. Comprehensive evaluation and interpretation of all this detailed information is required to understand the processes involved in organic matter-microbe interactions on a molecular and mechanistic level. In this session, we aim to bring together organic biogeochemists, microbial ecologists, physicists, computational data analysts and all other scientists who are interested in advancing the progress at the intersection of microbiology and organic matter biogeochemistry.
