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

The interaction of bio–geosphere dates to the formation of first unicellular microbes on earth.
However, it is only relatively recently that the complex biological interactions are observed …

Uncovers the Key Role Microbes Play in the Transformation of Oxidizable and Reducible
MineralsMany areas of geomicrobial processes are receiving serious attention from …

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 …

Caves have been an item of amateur and professional exploration for many years. Research
on the karst caves has revealed great diversity of bacteria, algae, and fungi living on stone …

Severe membrane fouling caused by iron and manganese limited the intensive application
of ultrafiltration (UF) technologies. In the present study, an innovative biofilm based UF …

Three identical lab-scale biofilters were employed to optimize the start-up process for
simultaneous removal of iron (Fe), manganese (Mn), and ammonia from potable water …

In this study, three bacteria with high Fe-and Mn-oxidizing capabilities were isolated from
groundwater well sludge and identified as Acinetobacter sp., Bacillus megaterium and …

Household sand filters are used in rural areas of Vietnam to remove As, Fe, and Mn from
groundwater for drinking water purposes. Currently, it is unknown what role microbial …

Biological Mn oxidation is responsible for producing highly reactive and abundant Mn oxide
phases in the environment that can mitigate metal contamination. However, little is known …
