Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv
attribute NC_GLOBAL acquisition_description String Isolation and isotopic analysis of squalenoids:
Cell pellets were freeze-dried overnight, ground with a clean spatula, and
extracted three times by sonication in a centrifuge tube filled with 50 mL of
3:1 dichloromethane:methanol (DCM:MeOH). All glassware was combusted overnight
at 500\u00b0C to remove organics prior to use. After sonication, the extracts
were spun in a centrifuge at 125 g for 15 min and the supernatant was decanted
to a separate vial. All extracts were combined and the solvent was evaporated
to dryness in a rotary evaporator.\u00a0 A maximum of 2 mL of 9:1 DCM:MeOH was
added to dissolve the total extract that was then passed over Na2SO4 to remove
water. The water-free extract was then separated into different fractions over
SepraTM NH2 bulk-packing (P/N 1001711653 572122 \u2013 U) silica column by
eluting with solvents of increasing polarity (F1 = 5 mL of hexane, F2 = 6 mL
of 3:1 hexane:DCM, F3 = 7 mL of 9:1 DCM:acetone, F4 = 8 mL of 4% formic acid
in DCM). The apolar fraction (F1) was dried under N2, then re-dissolved in 50
\u00b5L of hexane for identification.

The lipids in the apolar fraction were identified and quantified using an
Agilent Technologies 5975 inert XL Mass Selective Detector after separation on
an Agilent J&W GC HP-5MS UI capillary column (30 m \u00d7 0.25 mm i.d., 0.25
\u00b5m film thickness, P/N 19091S \u2013 433UIE) using He as the carrier gas.
Samples were injected in pulse splitless mode. The GC oven was from an initial
temperature of 70\u00b0C, then heated to 150\u00b0C at 15\u00b0C per min, then
to 300\u00b0C at 5\u00b0C per min. Peaks were quantified by comparison to a
5-point standard curve of a C7-C30 alkane series (P/N 49451 \u2013 U, Sigma
Aldrich). The isotopic composition of biomarkers in the apolar fraction was
determined on a Thermo Scientific Gas Chromatograph-IsolinkII-Isotope Ratio
Mass Spectrometer (GC-IsolinkII-IRMS) equipped with an Agilent DB-5 fused
silica column (30 m \u00d7 0.25 mm i.d., 0.25 \u00b5m film thickness) with He
as the carrier gas.

Isolation, characterization, and isotopic analysis of amino acids:
Pelleted cells were hydrolyzed with 6 M HCl (Ultrapure grade) with 1% of 11
mM ascorbic acid under N2 at 110\u00b0C for 20 h (Henrichs, 1991). After
cooling, hydrolyzed amino acids were spiked with internal standard norvaline
and derivatized with acidified isopropanol and acetyl chloride for 1 h at
110\u00b0C (Silfer et al., 1991). The samples then reacted at 110\u00b0C for 1
h on a hot plate. They were then esterified with trifluoroacetic anhydride
(TFAA) for 10 min at 110\u00b0C for 10 min. The resulting derivatives were
dissolved in dichloromethane. The isotopic signatures of derivatized amino
acids were determined by GC-IsolinkII-IRMS

attribute NC_GLOBAL projects_0_description String Project description from C-DEBI:
The microbial biosphere in serpentinizing subseafloor rocks is globally significant. Tantalizing evidence from studies of the Lost City Hydrothermal Field and continental ophiolites indicates that hydrogendriven microbial metabolisms prevails under the highly reducing, high pH conditions that characterize these environments. Interest in these processes is evident from an upcoming cruise to the Atlantis Massif in Fall 2015 to obtain drill cores in the vicinity of the Lost City Hydrothermal Field (IODP Expedition #357; both PIs were proponents of the IODP proposal and have applied as shipboard scientists). The PIs and colleagues have made headway over the last decade in identifying the key organisms and metabolisms present at the LCHF, and in constraining the sources and fates of carbon compounds. The linkages between geology and biology remain enigmatic, however, because of the precipitation of inorganic carbon at high pHs and overlapping biogenic and abiogenic carbon sources. We propose here to investigate the influence of free energy availability by sulfate reduction in resource utilization and carbon flow by model alkaliphilic prokaryotes. The laboratory approach using a model system will inform shipboard experiments with fresh samples from the AM, and the potential characterization of new organisms from serpentinizing terrains.
