• New processes and players in the nitrogen cycle: the microbial ecology of anaerobic and archaeal ammonia oxidation (2007, background): “Reports of N-fixation in 53.5- 63.41C hot spring cyanobacterial mats (Steunou et al., 2006), and at 921C in a deep-sea hydrothermal vent methanogen (Mehta and Baross, 2006), may be indicative of active N cycling in high-temperature environments.”
• Nitrogen fixation in the western English Channel (NE Atlantic Ocean) (2009, background): “…nitrogen fixation takes place in the brackish Baltic Sea each summer (e.g. Wasmund et al. 2005) and is also known to occur over environmental extremes including the Arctic tundra (Zielke et al. 2002), Antarctic freshwater (Davey 1982) and deep sea hydrothermal vent fluids (Mehta & Baross 2006).”
• Flat laminated microbial mat communities (2009, background): “The current record for nitrogenfixation is 92 °C, by a thermal vent methanogen (Mehta and Baross, 2006).”
• Impacts of Deep-Sea Mining on Microbial Ecosystem Services (2018, background): “…seawater (Karl et al., 1980; Huber et al., 2002; Meyer et al., 2013) with diverse metabolic capacities that affect global chemical cycling of carbon, nitrogen, iron, and sulfur (Mehta and Baross, 2006; Wankel et al., 2011; Holden et al., 2012; Bourbonnais et al., 2014; Fortunato et al., 2018).”
• Beyond the Calvin cycle: autotrophic carbon fixation in the ocean. (2011, background): “With autotrophic organisms catalyzing the reduction of nitrate to N2 or ammonium (e.g., Epsilonproteobacteria and Aquificales) and methanogens fixing N2 (Mehta & Baross 2006), the potential for a complete nitrogen cycle carried out solely by autotrophic organisms exists at vents.”
• Biological activity and the Earth's surface evolution: Insights from carbon, sulfur, nitrogen and iron stable isotopes in the rock record (2009, background): “The N isotopic signature of the biomass produced by chemosynthesis, via N fixation [70,80] is significantly depleted in 15N, with 15N values ranging from −9.”
