Microbial Ecosystems in Movile Cave: An Environment of Extreme Life [PDF]
Life, 2023 Movile Cave, situated in Romania close to the Black Sea, constitutes a distinct and challenging environment for life. Its partially submerged ecosystem depends on chemolithotrophic processes for its energetics, which are fed by a continuous hypogenic inflow of mesothermal waters rich in reduced chemicals such as hydrogen sulfide and methane. We sampled

Competition-cooperation in the chemoautotrophic ecosystem of Movile Cave: first metagenomic approach on sediments [PDF]
Environmental Microbiomes, 2022 Abstract Background Movile Cave (SE Romania) is a chemoautotrophically-based ecosystem fed by hydrogen sulfide-rich groundwater serving as a primary energy source analogous to the deep-sea hydrothermal ecosystems.

Aerobic proteobacterial methylotrophs in Movile Cave: genomic and metagenomic analyses [PDF]
Microbiome, 2018 Movile Cave (Mangalia, Romania) is a unique ecosystem where the food web is sustained by microbial primary production, analogous to deep-sea hydrothermal vents. Specifically, chemoautotrophic microbes deriving energy from the oxidation of hydrogen sulphide and methane form the basis of the food web.Here, we report the isolation of the first methane ...

Microbial eukaryotes in the suboxic chemosynthetic ecosystem of Movile Cave, Romania [PDF]
Environmental Microbiology Reports, 2019 Summary Movile Cave is a small system of partially inundated galleries in limestone settings close to the Black Sea in Southeast Romania. Isolated from the surface for 6 million years, its sulfidic, methane and ammonia‐rich waters harbour unique chemosynthetic prokaryotic communities that include sulphur and ammonium‐metabolizing ...

Draft Genome Sequence of the Methane-Oxidizing Bacterium “ Candidatus Methylomonas sp. LWB” Isolated from Movile Cave [PDF]
Genome Announcements, 2017 ABSTRACT We describe the draft genome sequence of “ Candidatus Methylomonas sp. LWB” isolated from Movile Cave microbial mat samples. The genome contains both the soluble and particular methane monooxygenase; however, one of the putative particulate methane monooxygenase gene clusters is ordered

Draft Genome Sequences of Facultative Methylotrophs, Gemmobacter sp. Strain LW1 and Mesorhizobium sp. Strain 1M-11, Isolated from Movile Cave, Romania [PDF]
Genome Announcements, 2015 ABSTRACT Facultative methylotrophs belonging to the genera Gemmobacter and Mesorhizobium were isolated from microbial mat and cave water samples obtained from the Movile Cave ecosystem. Both bacteria can utilize methylated amines as their sole carbon and nitrogen source.

Bacterial metabolism of methylated amines and identification of novel methylotrophs in Movile Cave. [PDF]
ISME J, 2015 Abstract Movile Cave, Romania, is an unusual underground ecosystem that has been sealed off from the outside world for several million years and is sustained by non-phototrophic carbon fixation. Methane and sulfur-oxidising bacteria are the main primary producers, supporting a complex food web that includes bacteria, fungi and cave ...

The Chemoautotrophically Based Movile Cave Groundwater Ecosystem, a Hotspot of Subterranean Biodiversity [PDF]
Diversity, 2021 Movile Cave hosts one of the world’s most diverse subsurface invertebrate communities. In the absence of matter and energy input from the surface, this ecosystem relies entirely on in situ primary productivity by chemoautotrophic microorganisms. The energy source for these microorganisms is the oxidation of hydrogen sulfide provided continuously from ...

A new extremophile ostracod crustacean from the Movile Cave sulfidic chemoautotrophic ecosystem in Romania [PDF]
Scientific Reports, 2023 Abstract Sulfidic cave ecosystems are remarkable evolutionary hotspots that have witnessed adaptive radiation of their fauna represented by extremophile species having particular traits. Ostracods, a very old group of crustaceans, exhibit specific morphological and ecophysiological features that enable them to ...

Alveolates (dinoflagellates, ciliates and apicomplexans) and Rhizarians are the most common microbial eukaryotes in temperate Appalachian karst caves. [PDF]
Environ Microbiol Rep, 2022 Summary The purpose of this study was to survey the eukaryotic microbiome of two karst caves in the Valley and Ridge physiographic region of the Appalachian Mountains. Caves are known to harbour eukaryotic microbes but their very low densities and small cell size make them difficult to collect and identify.
