“…Pyrite dissolution by iron‐ and sulfur‐oxidizing microorganisms has been reported (Edwards et al ., 1998 ; Fowler et al ., 1999 ; McGuire et al ., 2001 ; Druschel et al ., 2004 ). Interestingly, archaea with Fe and/or S assimilatory metabolisms have also been shown to dissolve iron sulfide compounds (Clarkson et al ., 2021 ; Payne et al ., 2021 ). Mesophilic methanogens are able to catalyse the reductive dissolution of pyrite allowing the liberation of Fe and S, which can be used for cellular biosynthesis (Payne et al ., 2021 ).…”

“…Mesophilic methanogens are able to catalyse the reductive dissolution of pyrite allowing the liberation of Fe and S, which can be used for cellular biosynthesis (Payne et al ., 2021 ). The hyperthermophile Pyrococcus furiosus is involved in the dissolution of mackinawite producing FeS complexes, which can then be re‐used by P. furiosus (Clarkson et al ., 2021 ). Further research is needed to identify the exact mechanisms of interactions between iron sulfides and T. kodakarensis .…”

Summary Thermococcales, a major order of archaea inhabiting the iron‐ and sulfur‐rich anaerobic parts of hydrothermal deep‐sea vents, have been shown to rapidly produce abundant quantities of pyrite FeS2 in iron–sulfur‐rich fluids at 85°C, suggesting that they may contribute to the formation of ‘low temperature’ FeS2 in their ecosystem. We show that this process operates in Thermococcus kodakarensis only when zero‐valent sulfur is directly available as intracellular sulfur vesicles. Whether in the presence or absence of zero‐valent sulfur, significant amounts of Fe3S4 greigite nanocrystals are formed extracellularly. We also show that mineralization of iron sulfides induces massive cell mortality but that concomitantly with the formation of greigite and/or pyrite, a new generation of cells can grow. This phenomenon is observed for Fe concentrations of 5 mM but not higher suggesting that above a threshold in the iron pulse all cells are lysed. We hypothesize that iron sulfides precipitation on former cell materials might induce the release of nutrients in the mineralization medium further used by a fraction of surviving non‐mineralized cells allowing production of new alive cells. This suggests that biologically induced mineralization of iron‐sulfides could be part of a survival strategy employed by Thermococcales to cope with mineralizing high‐temperature hydrothermal environments.

The mineral-microbe interactions play important roles in environmental change, biogeochemical cycling of elements, and formation of ore deposits. Minerals provide both beneficial (physical and chemical protection, nutrients, and energy) and detrimental (toxic substances and oxidative pressure) effects to microbes, resulting in mineral-specific microbial colonization. Microbes impact dissolution, transformation, and precipitation of minerals through their activity, resulting in either genetically-controlled or metabolism-induced biomineralization. Through these interactions minerals and microbes coevolve through Earth history. The mineral-microbe interactions typically occur at microscopic scale but the effect is often manifested at global scale. Despite advances achieved through decades of research, major questions remain. Four areas are identified for future research: integrating mineral and microbial ecology, establishing mineral biosignatures, linking laboratory mechanistic investigation to field observation, and manipulating mineral-microbe interactions for the benefit of humankind.
