Postdoctoral research associate - microbial physiology: Germany
The research group Geomicrobiology within the Department of Microorganisms of the Leibniz-Institute DSMZ-German Collection of Microorganisms and Cell Cultures GmbH offers the position of a Postdoctoral research associate (“Microbial pyrite formation – a novel energy metabolism”). The appointment will be initially for 2 years and is subject to extension based on a positive interim evaluation. The salary level will be according to TV-L 13. The position is offered as full time and is not appropriate for part-time work.
Pyrite is the most abundant iron-sulfur mineral in sediments. Over geological times, its burial in sediments controlled oxygen levels in the atmosphere and sulfate concentrations in seawater. The exergonic reaction of FeS with H2S to form FeS2 (pyrite) and H2 was also postulated as an early form of energy metabolism on primordial Earth. In a recent publication in PNAS (https://doi.org/10.1073/pnas.1814412116), we could show that a stable enrichment of microorganisms can mediate pyrite formation at ambient temperature and gain energy from this process. The aim of this project will be to decipher the pathway of pyrite formation and to identify those microorganisms in the enrichment, which drive this process. This will be achieved by a combination of metagenomics and metatranscriptomics, FISH analyses combined with RAMAN spectroscopy, electron microscopy, and cultivation-based approaches.
We seek a highly motivated and creative person with a track record in the fields of microbial physiology, molecular microbiology, and geomicrobiology. Candidates should hold a doctoral degree in microbiology or a similar research field. Working experience in meta-omics techniques, bioinformatics analyses, microscopy techniques and cultivation work is a pre-requisite. Familiarity with running bioreactors is considered as a plus.
