Lipid biomarkers have proved to be an excellent tool in many marine biogeochemical studies as they provide species, process specific information, or reflect environmental variables such as temperature and pH. One of the greatest strengths of lipid biomarkers, as opposed to other biological molecules, is their preservation potential over millions of years in the geological record. In order to unlock all potential information stored in preserved lipids, we need to know who produced them and under what conditions. As the vast majority of microorganisms are uncultured, associating lipids with their producers has in many cases been impossible. My aim is to enrich our understanding of which microorganisms produce which lipids and under what conditions in the ocean. In order to do this, I used two omic approaches, one established, genomics and one which is in its infancy in the field of biogeochemistry, lipidomics. Recently, we successfully developed a “non-targeted lipidomic” approach to comprehensive lipidome profiling. The next step is to establish a work-flow that combines comprehensive profiling of microbial communities and of biomarker lipids in a variety of marine environments. This novel workflow will provide not only more comprehensive recognition of novel lipid biomarkers from uncultivated microbes but will also shed light on globally important biogeochemical processes.
