Kleine Zellen, große Wirkung – Bakterien der Candidate Phyla Radiation

Abstract

Recent genomic studies indicate that the diversity of the so-called
Candidate Phyla Radiation (CPR) comprises approximately 26 percent of
the entire catalogued biodiversity. These bacteria are characterized by
small cell-size and a reduced metabolism. In this review, we provide a
short overview of their diversity and ecological distribution, particularly
with respect to the human microbiome. We finally summarize cultivation
attempts and known symbioses and provide insights into their known
metabolism.
