Abstract

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 × 10 3 to 3.6 × 10 4 cells per milliliter; no biological incorporation of selected organic substrates or bicarbonate was detected. Bacterial 16 S 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 the Actinomycetes. Extrapolation of the data from accretion ice to Lake Vostok implies that Lake Vostok may support a microbial population, despite more than 10 6 years of isolation from the atmosphere.

  6. Core 3590 was a longitudinal cut from a 10-cm-diameter 44-cm-long core obtained from Vostok hole 5G. The core had minor cracking propagating <3 cm into the sidewall and no exsolved clathrates. Nonaggregated sediments were dispersed throughout the core and five sediment inclusions ranging from 0.5 to 1 mm in diameter were present. Core sections were cut for analyses with a saw sterilized with ethanol. Samples were processed under a sterile positive-pressure laminar flow hood; sterile gloves clean laboratory clothing and hair covering were worn during handling. All core handling was conducted in a laboratory that had never been used to grow or process biological samples. Ion and trace chemical samples were rinsed thoroughly with 0.2-μm–filtered Barnstead-nanopure water until 4 to 10 mm of the outer surface had melted. The samples were then completely melted at room temperature in clean sterile high-density polyethylene (HDPE) jars. Ions in filtered (0.2 μm) and unfiltered samples were analyzed by ion chromatography [

Stable isotope samples were melted without rinsing and analyzed by mass spectrometry. SEM samples were rinsed and melted as for ion chemistry. Melted SEM samples were filtered onto sterile 0.2-μm filters with cleaned and sterilized equipment. A SEM control was prepared with 0.2-μm–filtered nanopure water frozen in a clean sterile polycarbonate tube. The control core was melted filtered and analyzed by SEM with methods identical to those of the sample. Mineral and biological particles from the sample were unique with respect to that observed in the control core indicating that the sample portions we analyzed were free from particulate matter contamination. A sample for epifluorescence microscopy of acridine orange– stained cells was melted in an acid-washed autoclaved bottle at 4°C. DNA staining and counting protocols are described in (31).

  16. Cryogenic SEM (JEOL-6100 SEM) and energy dispersive spectrometry (EDS) were used to image and analyze particles captured by 0.2-μm filtration of melted ice (EDS could only be used on particles >1 μm in diameter). Atomic force microscopy used a Digital Instrument's Dimension 3100 system in tapping mode.

  33. DOC was determined with a Shimadzu TOC-5000A carbon analyzer. Standards were mixed from NIST traceable potassium hydrogen phthalate. All sample glassware was prepared by soaking in NoChromix acid solution for 8 hours followed by six nanopure deionized water rinses and 8 hours of baking at 500°C. The sample was acidified with 2 M HCl (ACROS 37% HCl and ultrapure water) and sparged with U.S.P. grade oxygen for 5 min to remove CO 2 . Six replicate injections yielded a coefficient of variation of 2%.

  36. Ice for radiolabeled substrate incorporation experiments was rinsed with −10°C 95% ethanol followed by nanopure water before melting at 4°C in a sterile HDPE container. Five-milliliter portions were placed in sterile test tubes and inoculated with isotopes to the following activities and concentrations: 14 C-bicarbonate (9.5 × 10 5 dpm ml −1 trace addition) tritiated thymidine (2.1 × 10 8 dpm ml −1 ; 36 nM) tritiated d -mannitol (2.2 × 10 8 dpm ml −1 ; 7.5 nM) and tritiated l -amino acid mix (1.3 × 10 4 dpm ml −1 0.31 μg ml −1 ). Three live replicates and one 5% formalin kill were included for each substrate addition. Samples were incubated in the dark at 4°C for 52 hours in air at 1 atm. Carbon 14–labeled bicarbonate and 3 H-labeled thymidine incubations were terminated by the addition of 0.5 ml of 6 M HCl and 5 ml of cold 10% trichloroacetic acid (TCA) respectively before filtration onto 0.2-μm polycarbonate filters; 3 H-labeled mannitol incubations were terminated by filtration alone.

  38. Ice for cultures was rinsed with −20°C ethanol followed by autoclaved distilled and organic free water. The ice was melted at 4°C for 12 hours in an autoclaved HDPE bottle that had been rinsed with organic free deionized water. One milliliter of melted core water was inoculated into two liquid media: phosphate (1.44 g liter −1 Na 2 HPO 4 and 0.24 g liter −1 KH 2 PO 4 )-buffered sterile deionized water (pH 7.4) and sterile water containing 0.05% (w/v) peptone (pH 7.4). Meltwater (0.5 ml) was also spread onto sterile agar (15 g liter −1 ) plates prepared with the same media. The inoculated media were incubated for 4 months at 4°C in air at 1 atm in the dark (liquid media preparations were on a shaker during incubation).
