Characterization of the bacterial communities on recent Icelandic volcanic deposits of different ages
Abstract Background Basalt is the most common igneous rock on the Earth’s surface covering. Basalt-associated microorganisms drive the cycling and sequestration of different elements such as nitrogen, carbon and other nutrients, which facilitate subsequent pioneer and plant development, impacting lo...
