Microbial lipids: The three domain “lipid divide”
Tremendous progress has been made in the last decade in the genetic characterization of microorganisms, both in culture and in the environment. However, our knowledge of microbial membrane lipids, essential building blocks of the cell, has only marginally improved. This is remarkable since there exists a dichotomy in the distribution of lipids between the three Domains of Life. Diacyl glycerols based on straight-chain fatty acids are produced by bacteria and eukaryotes, whereas archaea synthesize isoprenoidal glycerol ether lipids. From a microbial evolutionary perspectives, this ‘lipid divide’ is enigmatic since it has recently become clear that eukaryotes evolved from the archaea. When novel analytical methodology is used, there is a large hidden diversity in microbial lipid composition that may resolve this fundamental question. We propose to systematically characterize prokaryotic intact polar lipids with state-of-the-art analytical techniques based on liquid chromatography and high-resolution mass spectrometry to bring our knowledge of microbial lipids to the next level.
Novel biomarkers for symbiotic N2 fixing cyanobacteria in marine diatoms.
This research project focuses on tracing marine symbiotic heterocystous cyanobacteria in present and past marine environments. It is important to gain more knowledge about these cyanobacteria because they are sustaining marine primary production in the oligotrophic ocean. The development of a new glycolipid biomarker will allow the investigation of cyanobacteria – diatom symbioses in the natural environment and assess the importance for present day fixation of dinitrogen in the ocean. In addition, the application of this new tracer to analyze the sediment record has the unique potential to improve our knowledge of the paleo-N-cycle. Elucidating the contribution of dinitrogen-fixing cyanobacteria in the past when the atmospheric CO2 levels were high will give clues to predict changes in the nitrogen cycle during the expected high CO2 future.

Detailed study of the nitrogen cycle in the North Sea and Wadden Sea
This research formed part of a multi-disciplinary project entitled “The nitrogen cycle and changes in the carrying capacity of coastal waters (NICYCLE)”. This project, funded as part of the Dutch National Program for Sea and Coastal Research (ZKO), performed an extensive study of key nitrogen cycling microorganisms in the Netherlands’ coastal waters, the North and Wadden Seas. My strength is in analytical chemistry and my work within this project concentrated on the specific intact polar lipids (IPLs) associated with nitrogen cycling microorganisms in order to trace their activity and diversity, using organic geochemical techniques such as liquid chromatography- multistage mass spectrometry (LC-MS/MS).
