Data from ice 3590 meters below Vostok Station indicate that the ice was accreted from liquid water associated with Lake Vostok. Microbes were observed at concentrations ranging from 2.8 x 10(3) to 3.6 x 10(4) cells per milliliter; no biological incorporation of selected organic substrates or bicarbonate was detected. Bacterial 16S ribosomal DNA genes revealed low diversity in the gene population. The phylotypes were closely related to extant members of the alpha- and beta-Proteobacteria and… Expand
Microorganisms in the accreted ice of Lake Vostok, Antarctica.
TLDR
Analysis of accreted ice data suggest that Lake Vostok may contain viable microorganisms, and at least a portion of the microbial assemblage was viable, as determined by the respiration of carbon-14-labeled acetate and glucose substrates during incubations at 3 degrees C and 1 atmosphere. Expand
Limnological conditions in Subglacial Lake Vostok, Antarctica
Subglacial Lake Vostok is located ,4 km beneath the surface of the East Antarctic Ice Sheet and has been isolated from the atmosphere for .15 million yr. Concerns for environmental protection haveExpand
Isolation of bacteria and 16S rDNAs from Lake Vostok accretion ice.
TLDR
The recovery of bacterial isolates belonging to the Brachybacteria, Methylobacterium, Paenibacillus and Sphingomonas lineages are reported from a sample of melt water from this accretion ice that originated 3593 m below the surface. Expand
Microflora in the basal strata at Antarctic ice core above the Vostok lake.
TLDR
The discovered stratification is apparently connected with the periodicity of the lake water interactions with the basal ice layer and obviously depends on the complex natural events which took place in the geological history of the authors' planet. Expand
Isolation of Bacteria and Fungi from Lake Vostok Accretion Ice
Scott O. Rogers, Advisor Lake Vostok, located below the 4000 m thick Antarctic Ice Sheet, is the largest subglacial lake in Antarctica. The lake water has not been sampled due to concerns of forwardExpand
MICROBIAL LIFE IN EXTREME SUBGLACIAL ANTARCTIC LAKE ENVIRONMENTS : LAKE VOSTOK
The objective of the study was to estimate microbial content in accretion (frozen lake water) ice from Lake Vostok buried beneath 4-km thick East Antarctic ice sheet. The ultimate goal of the studyExpand
Ice formation in subglacial Lake Vostok, Central Antarctica
Abstract The investigation of chemical and isotopic properties in the lake ice from the Vostok ice core gives clues to the mechanisms involved in ice formation within the lake. A small lake waterExpand
Bacteria beneath the West Antarctic ice sheet.
TLDR
The first report of microbes in samples from the sediment environment beneath the Antarctic Ice Sheet is reported, and it is clear that the subglacial ecosystem contains a significant and previously unrecognized pool of microbial cells and associated organic carbon that could potentially have significant implications for global geochemical processes.

Subglacial Lake Vostok (Antarctica) Accretion Ice Contains a Diverse Set of Sequences from Aquatic, Marine and Sediment-Inhabiting Bacteria and Eukarya
Lake Vostok, the 7th largest (by volume) and 4th deepest lake on Earth, is covered by more than 3,700 m of ice, making it the largest subglacial lake known. The combination of cold, heat (fromExpand
Ecology of Subglacial Lake Vostok (Antarctica), Based on Metagenomic/Metatranscriptomic Analyses of Accretion Ice
TLDR
Lake Vostok is the largest of the nearly 400 subglacial Antarctic lakes and has been continuously buried by glacial ice for 15 million years, and appears to contain a mixture of autotrophs and heterotophs capable of performing nitrogen fixation, nitrogen cycling, carbon fixation and nutrient recycling.

More than 200 meters of lake ice above subglacial Lake Vostok, Antarctica.
TLDR
Isotopic data suggest that subglacial Lake Vostok is an open system with an efficient circulation of water that was formed during periods that were slightly warmer than those of the past 420,000 years. Expand
Perennial Antarctic lake ice: an oasis for life in a polar desert.
TLDR
The permanent ice covers of Antarctic lakes in the McMurdo Dry Valleys develop liquid water inclusions in response to solar heating of internal aeolian-derived sediments for the establishment of a physiologically and ecologically complex microbial consortium capable of contemporaneous photosynthesis, nitrogen fixation, and decomposition.

TLDR
Bacterial production and cell numbers measured within four Antarctic seasons imply that bacteria may be a source of carbon to higher trophic levels in these lakes, through grazing. Expand
