[2016]). Fluids were collected using isobaric\ngas-tight samplers [Seewald et al., 2002] prior to their transfer to the\nshipboard continuous culture system [Foustoukos and Perez-Rodriguez, 2015].\nHere, high-pressure incubations (250 bars) were conducted at mesophilic (30\n\\u00baC) and thermophilic (50 \\u00baC) conditions to constrain the function\nand metabolic rates of denitrifying and DNRA microbial communities residing at\nCrab Spa and Alvinella, respectively. To enhance the activity of nitrate-\nrespiring anaerobic bacteria, an NO3- (5 mm) and H2(aq) (1.30 mM)-enriched\nmedium was introduced in the high-pressure incubations under strictly\nanaerobic conditions. Dissolved HCO3- (7.3 mm, 13C labeled) was used as added\ncarbon source. Vent fluids were introduced at a flow rate of 0.042 mL/min,\nwhile growth medium was added at a rate of 0.0042 mL/min. The two sets of\nexperiments were performed for 356 (Crab Spa) and 50 hours (Alvinella). Direct\ncell counts were conducted by staining cells with 0.1% acridine orange and\ncounting them with a fluorescence microscope. 15N/14N isotopic analysis of the\nNO3-, NH4+ and biomass were conducted with a Thermo Scientific Delta VPlus\nmass spectrometer and CE Instruments NA 2500 series elemental analyzer (EA).\n \nReferences:\n \nFoustoukos, D., and I.
