Biofilms are microbial communities attached to surfaces and encased in an extracellular
matrix of microbial origin. They represent the predominant form of microbial life. Biofilms are …

Relatively stable physical conditions in caves allow for the examination of the relationship
between geochemical processes and the activity of microorganisms, reflected in substantial …

Caves are typified by their permanent darkness and a shortage of nutrients. Consequently,
bacteria play an important role in sustaining such subsurface ecosystems by dominating …

The composition of extracellular polymeric substances (EPS) from Shewanella sp. HRCR‐1
biofilms was investigated using infrared spectroscopy and proteomics to provide insight into …

Relatively few studies have described the microbial populations present in ultra-deep hadal
environments, largely as a result of difficulties associated with sampling. Here we report …

Despite extremely starved conditions, caves contain surprisingly diverse microbial
communities. Our research is geared toward understanding what ecosystems drivers are …

In soluble rocks such as limestone and dolostone there are two main types of cave genesis
(speleogenesis);(i) epigenic speleogenesis, in which the aggressiveness that forms caves is …

Biodegradation of anthropogenic pollutants in shallow aquifers is an important microbial
ecosystem service which is mainly brought about by indigenous anaerobic microorganisms …

The Frasassi and Acquasanta Terme cave systems in Italy host isolated lithoautotrophic
ecosystems characterized by sulfur-oxidizing biofilms with up to 50% S (0) by mass. The net …

Caves are relatively accessible subterranean habitats ideal for the study of subsurface
microbial dynamics and metabolisms under oligotrophic, non-photosynthetic conditions. A …
