Extremophiles survive under extreme environmental conditions. Using particular cellular strategies, they can even thrive under conditions once thought too extreme for life to exist. One of these extremes is very high salt concentration, a condition which harbors halophiles. Read about high salinity environments and their inhabitants in this collection FEMS Microbiology Letters and FEMS Microbiology Ecology.

FEMS Journals and Open Access

Embracing an Open Future

All but one of the FEMS journals are now fully open access (OA), with one journal, FEMS Microbiology Letters remaining a subscription journal with free-to-publish and OA options. Open access is key to supporting the FEMS mission of disseminating high quality research as widely as possible: when high quality, peer reviewed sound science is open access, anyone, anywhere in the world with an internet connection, can read it.
