Abstract: The chemical stress factors for microbial life at deep-sea hydrothermal vents include high concentrations of heavy metals and sulfide. Three hyperthermophilic vent archaea, the sulfur-reducing heterotrophs Thermococcus fumicolans and Pyrococcus strain GB-D and the chemolithoautotrophic methanogen Methanocaldococcus jannaschii, were tested for survival tolerance to heavy metals (Zn, Co, and Cu) and sulfide. The sulfide addition consistently ameliorated the high toxicity of free metal cations by the formation of dissolved metal-sulfide complexes as well as solid precipitates. Thus, chemical speciation of heavy metals with sulfide allows hydrothermal vent archaea to tolerate otherwise toxic metal concentrations in their natural environment.

Life in the slow lane; biogeochemistry of biodegraded petroleum containing reservoirs and implications for energy recovery and carbon management
TL;DR: A synthesis of new and existing microbiological, geochemical, and biogeochemical data is presented that proposes that the salinity of reservoir formation waters exerts a key control on the occurrence of biodegraded heavy oil reservoirs and introduces the concept of palaeopickling.

Microbial Ecology of Mid‐Ocean Ridges and Back‐Arc Basins
TL;DR: A review of microbial ecology and microbial ecophysiology at vents and patterns of diversity emerging from studies in the global hydrothermal systems can be found in this paper, where the authors highlight several case studies on Hydrothermal vent microbial communities in BAB systems that are comparable to the communities in mid-ocean ridge (MOR) systems.

The impact of Co and Ni speciation on methanogenesis in sulfidic media - Biouptake versus metal dissolution
TL;DR: In this paper, the speciation of the trace nutrients Co(II) and Ni(II), in sulfide containing media can control the methanogenic activity of Methanosarcina sp., which is of importance for the optimisation of anaerobic treatment of wastewater containing methanol.
