2012;28:1420–8. In view of the fact that membrane-bound nitrate reductase encoded by nar is more efficient than the nap-encoded periplasmic nitrate reductase at high nitrate concentrations , the higher frequency of nar gene observed in the M-vent possibly reflects the microbial adaption to the increased accessibility of nitrate, implying that the intrusion of seawater plays an important role in the microbial succession after venting ceases. Here, the metagenome of a sulfide chimney that became recently inactive (~ 7 years prior to sampling) is being compared with an actively venting chimney from the same hydrothermal vent field located on the East Pacific Rise at 9–10° N. Their microbial communities have distinct compositional structures and energy-yielding metabolic potentials, indicating that the changes of the microbial community are largely driven by the available energy sources that shift from venting fluids to the mineral phase as the hydrothermal activity diminishes. 2013;31:533–8. Microb Ecol. Wirth R. Colonization of black smokers by hyperthermophilic microorganisms. Nematode succession at deep-sea hydrothermal vents after a recent volcanic eruption with the description of two dominant species Sabine Gollner & Maria Miljutina & Monika Bright Received: 1 August 2012 /Accepted: 17 December 2012 /Published online: 20 January 2013 # Gesellschaft für Biologische Systematik 2013 Based on the analysis of MAGs, the Gammaproteobacteria (16 MAGs) dominating the M-vent chimney are potential chemoautotrophic sulfur-oxidizing bacteria, using the CBB cycle for carbon fixation and reducing nitrate via the DNRA pathway (Fig. Most Campylobacteria identified at DSHV are uncultured, but information on available isolates and incubation studies suggests that they are either thermophiles or mesophiles with the capability of chemoautotrophy driven by oxidation of H2 and/or H2S dissolved in the vent fluids [14, 28,29,30,31,32]. These are porous geological structures produced by chemical reactions between solid rock and water. The rTCA cycle is the sole carbon fixation pathway and was prevalently identified in the Aquificae and Campylobacteria MAGs (55% and 47%, respectively). JSS measured and provided the chemical data. The red nodes represent those MAGs recovered from L-vent chimney. 2015;91:1–11. The P values are based on Fisher’s exact test and corrected by Benjamini-Hochberg FDR. Forest ecosystems are able to gradually replenish themselves after being destroyed by massive forest fires. Sondergaard D, Pedersen CN, Greening C. HydDB: a web tool for hydrogenase classification and analysis. 2016;34:1256–63. In addition, the majority of Aquificae and Campylobacteria MAGs encode hydrogenase groups 1 and 2 for hydrogen uptake. Google Scholar. SC-1, a FeOB recently isolated from an in situ incubation with pyrrhotite, has been shown to grow autotrophically with iron oxides and sulfur intermediates [30, 90]. Front Microbiol. Temporal and spatial archaeal colonization of hydrothermal vent deposits. In addition, FCB group (11 MAGs; 4.99%), Calditrichaeota (6 MAGs; 3.72%), Alphaproteobacteria (7 MAGs; 2.77%), Nitrospirae (6 MAGs; 2.94%), PVC group (9 MAGs; 4.35%), and Acidobacteria (4 MAGs; 2.57%) were represented as major microbial groups among the MAGs of the M-vent microbial community. Tivey MK. Colonization is followed by the thermophilic Aquificae and thermophilic and mesophilic Campylobacteria, which colonize the relative cooler exterior layers of the chimney wall and often form massive biomats covering the chimney exterior [20, 21]. Mol Biol Evol. Vent fields are isolated by uninhabitable deep seafloor, so recolonization via dispersal of planktonic larvae is critical for persistence of populations.
