Project description
Looking for signs of microbial-mineral cooperation and life remnants in gypsum deposits
Stromatolites are laminated rocky structures made by tiny, sun-loving microorganisms. They comprise the oldest undisputed evidence of fossil life on Earth, dating back more than 3.5 billion years. Lake Bakili in Ethiopia hosts atypical stromatolites made of gypsum whose challenging accessibility has left them largely unexplored. With the support of the Marie Skłodowska-Curie Actions programme, the interdisciplinary NanoBioS project will study the microbiology and mineralogy of these newly discovered stromatolites. Scientists are looking for evidence of mineral-microbial interactions and potential remnants of living organisms in the stromatolites to better understand mineral-microbial synergy and shed light on how to distinguish inorganic biomorphs from real fossils in gypsiferous deposits.
Objective
Gypsum-based stromatolites (GS) make excellent paradigms for the investigation of fine-scale mineral-microbial interactions and for the detection of life remnants on gypsiferous deposits of Earth and Mars. Yet, they have been largely overlooked compared to the carbonate microbialites. To date we do not know: i) what is their exact mineralogy, ii) which microbial communities are associated to these structures, iii) what is the exact role of microbes and related bioproducts (e.g. exopolymeric substances) in mineral precipitation and stromatolite construction, and iv) which biosignatures may be preserved in GS.
NanoBioS aims to address this knowledge gap by employing an interdisciplinary approach to study newly discovered gypsum-based stromatolites from Lake Bakili (Danakil Depression, Ethiopia) from a combined microbiology and mineralogy perspective. The Danakil Depression and the difficult-to-access and so-far unexplored Lake Bakili constitute a unique, natural laboratory for the study of both living and fossil gypsum microbialites, and a terrestrial Martian analogue-site. Besides the possibility to discover novel microbial lineages/metabolisms, we will attempt to identify characteristic associations of microbial groups with mineral assemblages and look for biosignatures. The overarching goal of NanoBioS is to gain a deeper understanding of the microbial influence on Ca-sulfate precipitation, as well as, to develop insights for distinguishing fossil life remnants from inorganic biomorphs on Earth and Martian chemical sediments.
The host and secondment host laboratories that have advanced the subject of geomicrobiology of microbialites, will offer me intensive training in cutting-edge molecular biology and mineralogic tools, complementary to my so far geochemical expertise, aside to other, transferable skills. Overall, the development of NanoBioS will be career-defining and it will transform me in an independent, highly competitive, early stage bio-geo-chemist.
