Cave and Karst Systems of Romania, 2018
Movile Cave (SE Romania) is the first known subterranean chemosynthesis-based ecosystem. Sulfur- and methane-oxidizing, as well as nitrifying microorganisms, form the base of the food web in this peculiar ecosystem. The bacteria use mainly oxygen from the cave’s atmosphere as electron acceptor to oxidize H2S, CH4, and NH4+, which originate from the ...

Niche specialisation and aerobic trace gas utilising microbes in Movile Cave
Karst Science Days Symposium ProceedingsThe isolation of cave ecosystems from dynamic surface environments gives them relatively stable conditions, allowing underlying features of the cave, such as geochemistry, hydrology and microbial biogeochemical cycling to be the driving influences on the

Up to the present, the genus Archiboreoiulus included only two species: A. sollaudi from France and A. pallidus with a wide European distribution range. Here we describe a previously unknown species of the genus Archiboreoiulus, A.

Analysis of methanotrophic bacteria in Movile Cave by stable isotope probing.
Environmental Microbiology, 2003Summary Movile Cave is an unusual groundwater ecosystem that is supported by in situ chemoautotrophic production. The cave atmosphere contains 1–2% methane (CH 4 ), although much higher concentrations are found in gas bubbles that keep

Preliminary Evidence for a Sulphur Cycle in Movile Cave, Romania
Acta Biotechnologica, 2003AbstractIn order to investigate the food chain and energy balance of the chemolithoautotrophically‐based ecosystem of the sulphur spring in Movile Cave as a model system for extraterrestrial life, a first sampling campaign was done. Microbial diversity and activity were analysed by MPN‐enumeration methods and microcalorimetry, respectively. In addition,

Karst Science Days Symposium Proceedings
Aquatic ecosystems characterized by naturally elevated concentrations of hydrogen sulfide (H2S) occur worldwide, in both marine and freshwater environments, where H2S is generated through geochemical or biological processes (Engel, 2007; Greenway et al.,

Nematology, 2007
AbstractThe life cycle and somatic growth of two bacterivorous nematodes, Panagrolaimus sp. and Poikilolaimus sp., isolated from chemoautotrophic microbial mats in Movile Cave, Romania, were studied in monoxenic cultures at 20°C with Escherichia coli as the food source.

METHYLATED AMINE-UTILISING BACTERIA AND MICROBIAL NITROGEN CYCLING IN MOVILE CAVE [PDF]
, 2014 Movile Cave is an unusual, isolated ecosystem which harbours a complex population of microorganisms, fungi and endemic invertebrates. In the absence of light and with no fixed carbon entering the cave, life is sustained by non-phototrophic microorganisms such as sulfur and methane oxidisers.
