The Project
Some studies have suggested that marine Archaea recycle their membrane lipids to decrease energy requirements. With the exception of Thaumarchaeota, the membrane lipid composition of most marine Archaea is unknown therefore it also uncertain their potential impact on the archaeal lipid pool preserved in the sedimentary record. In addition, recent genomic studies of some archaeal groups, which seem to be an important component of the Archaea community in marine settings, suggest they lack the genes of the membrane lipid biosynthetic pathway, suggesting these archaea might rely on host cells or cell debris for the synthesis of their lipid membrane.

In this project we want to further investigate the potential membrane lipid recycling and remodeling among Archaea in marine systems. For this aim, we will apply cultivation independent techniques based on incubation studies, and ‘omic’ approaches (DNA/RNA and lipids). The candidate will be trained in a wide range of analytical methods including lipid biomarker, stable isotope assays, as well as microbiological and molecular techniques.

The Candidate
We are looking for a highly motivated student with a background in environmental microbiology, geosciences, biogeochemistry or microbial ecology, and a Diploma or MSc certification in one of the mentioned areas. Experience with microbiology and/or molecular microbial ecology techniques is beneficial. Due to the international character of the research group, excellent English communication skills are expected.

Fixed-term contract: 4 years.

We are offering fulltime positions for 4 years, a pension scheme, a yearly 8% vacation allowance, year-end bonus and flexible employment conditions. Conditions are based on the Collective Labour Agreement of Research Centers. The position will be located on Texel. Cost of relocation and help with housing is provided by NIOZ.

The Department of Marine Microbiology and Biogeochemistry on Texel performs detailed studies on microbial communities in the marine environment. We study the diversity, physiology and activity of phytoplankton, prokaryotes (archaea and bacteria) and viruses in diverse marine environmental settings by a variety of techniques, including modern genomic techniques.
