Definition
Cave biofilms are biofilms or microbial mats that flourish in natural or anthropogenic cave settings. A biofilm is a three-dimensional assemblage of microbial communities that are embedded within a self-produced matrix of extracellular polymeric substances adhered to a surface. Depending on the geochemical and geological setting of a cave, biofilms comprised of variable microbial community compositions and metabolic processes can profoundly impact the speleogenetic history of a cave and the overall ecology of the cave setting.
Introduction
Caves are natural, solutionally or collapse-enlarged openings that form in rock, including but not limited to limestone, granite, lava, salt, or even ice. Caves are widely distributed geographically and can offer portals into different types of extreme, “dark life” habitats, such as the...
