What's up down there? Microbial diversity in caves
Caves provide relatively accessible sites in which individual species and microbial communities grow to levels approaching 106 cells/gram of rock under near-starvation conditions. • Cave-dwelling oligotrophic microbial species are phylogenetically diverse, with lineages across the breadth of the Bacteria. • Bacterial communities in caves acquire energy by several means, including by breaking down aromatic compounds, fixing gases, and oxidizing reduced metals within rocks. • By interacting with minerals, microbial species play an important role in reshaping the mineral environment of caves, and may help to form features such as stalactites and stalagmites.
