The environmental conditions of caves shape microbiota. Within caves' microbial
communities, actinomycetes are among the most abundant bacteria. Cave actinomycetes …

In this article, we provide a review of geomicrobiological interactions in caves, which are
nutrient-limited environments containing a variety of redox interfaces. Interactions of cave …

In the field of microbial biomineralization, much of the scientific attention is focused on
processes carried out by prokaryotes, in particular bacteria, even though fungi are also …

Earth's subsurface offers one of the best possible sites to search for microbial life and the
characteristic lithologies that life leaves behind. The subterrain may be equally valuable for …

To determine if microbial species play an active role in the development of calcium
carbonate (CaCO 3) deposits (speleothems) in cave environments, we isolated 51 …

Karst environments are regions where sparingly soluble rocks outcrop and efficient acid
hydrolysis creates spectacular dissolution landforms. The release of CO 2 from karst waters …

Calcrete is a general term given to the near-surface, terrestrial accumulation of
predominantly calcium carbonate, which occurs in a variety of forms from powdery to …

Laboratory experiments involving calcium carbonate precipitation by bacteria isolated from
stalactites sampled from three caves in Sahastradhara, Dehradun, India were conducted to …

In this study, we show that moonmilk subaerial speleothems in Altamira Cave (Spain)
consist of a network of fiber calcite crystals and active microbial structures. In Altamira …

Moonmilk is a karstic speleothem mainly composed of fine calcium carbonate crystals
(CaCO3) with different textures ranging from pasty to hard, in which the contribution of biotic …
