Scientific paper

Studies of microbial life in the deep marine subsurface can be used as a model system for the detection of possible microbial life on Mars. Focussed on the methodology, we tested four different approaches to evaluate the number, the identity and the function of the existing microorganisms in deep-sea sediments from the Peru Margin. Specifically, we applied the combined microscopic/molecular method FISH, organic biomarker studies, stable isotopes, DNA isolation and 16S rRNA analysis, and direct cultivation of microorganisms. With this set of methods, the microbial diversity was estimated in that extreme environment.
