Welcome to ISSM!

The International Society for Subsurface Microbiology is a unique group made up of microbiologists, ecologists, geoscientists, and other researchers and students around the world who are captivated with the various aspects of subsurface microbiology, a rapidly expanding field that focuses on microbial life below the surface of the earth.

Coming – ISSM 2020

Utrecht, Netherlands

Integrating microbiology and the geosciences

Integrating microbiology and the geosciences, the field of subsurface microbiology explores the ecology and evolution of microbial life in subsurface environments such as marine sediments, terrestrial groundwater, and the deep subsurface. The outcomes of this research can affect our current state-of-knowledge and future advancements in many industries.
