We live in a world that is dominated by microbial life. Despite that this ‘unseen majority’ drives major biochemical cycles on our planet, the extent of the molecular and functional diversity of these prokaryotes and protists has been poorly mapped. One important reason for this is that only about 1% of all microbial species can be cultured under laboratory conditions. In the recent years, culture-independent methods, such as metagenomics and single cell genomics have been developed that allow for the genomic exploration of this so-called "microbial dark matter".
