“…Pyrite dissolution by denitrifying microorganisms has been of interest for the past few decades due to its environmental interest (Postma et al, 1991;Schwientek et al, 2008;Zhang et al, 2009) and several studies support that pyrite can be used as electron donor by denitrifying chemolithotropic microorganisms (Jørgensen et al, 2009;Torrentó et al, 2010Torrentó et al, , 2011Bosch et al, 2012;Vaclavkova et al, 2015). Nevertheless, preliminary studies showed that Acidovorax BoFeN1 is not capable of dissolving pyrite or, at least, does not produce sulfate increment into the medium when it grows in the presence of this mineral (Yan et al, 2019). It should be noted, however, that other sulfur species such as thiosulfate or tetrathionate, which are more stable at neutral pH, may have been released into the medium instead of sulfate (Moses et al, 1987;Moses and Herman, 1991).…”

Despite being considered an extreme environment, several studies have shown that life in the deep subsurface is abundant and diverse. Microorganisms inhabiting these systems live within the rock pores and, therefore, the geochemical and geohydrological characteristics of this matrix may influence the distribution of underground biodiversity. In this study, correlative fluorescence and Raman microscopy (Raman-FISH) was used to analyze the mineralogy associated with the presence of members of the genus Acidovorax, an iron oxidizing microorganisms, in native rock samples of the Iberian Pyrite Belt subsurface. Our results suggest a strong correlation between the presence of Acidovorax genus and pyrite, suggesting that the mineral might greatly influence its subsurface distribution.

“…Nevertheless, Yan et al . (2018) demonstrated that even with S 0 impurities in their experiments, about 4% of the pyrite‐S must have been oxidized by T. denitrificans in order to explain the amount of sulfate produced. Overall, these studies demonstrated that the particle size of pyrite controls its bioavailability.…”

“…The most recent study by Yan et al . (2018) highlighted the possibility that these previous studies may be misleading as bioavailable elemental sulphur (S 0 ) particles are common impurities associated with pyrite that was not pre‐treated with organic solvents. Indeed, earlier studies found no pyrite oxidation when microbes were incubated in the presence of solvent‐washed pyrite (Schippers and Jorgensen, 2002; Haaijer et al ., 2007).…”

Nanoparticles are ubiquitous and co-occur with microbial life in every environment on Earth. Interactions between microbes and nanoparticles impact the biogeochemical cycles via accelerating various reaction rates and enabling biological processes at the smallest scales. Distinct from microbe-mineral interactions at large, microbe-nanoparticle interactions may involve higher levels of active recognition and utilization of the reactive, changeable, and thereby 'moldable' nano-sized inorganic phases by microbes, which has been given minimal attention in previous reviews. Here we have compiled the various cases of microbe-nanoparticle interactions with clear and potential benefits to the microbial cells and communities. Specifically, we discussed (i) the high bioavailabilities of nanoparticles due to increased specific surface areas and size-dependent solubility, with a focus on environmentally-relevant iron(III) (oxyhydr)oxides and pyrite, (ii) microbial utilization of nanoparticles as 'nano-tools' for electron transfer, chemotaxis, and storage units, and (iii) speculated benefits of precipitating 'moldable' nanoparticles in extracellular biomineralization. We further discussed emergent questions concerning cellular level responses to nanoparticle-associated cues, and the factors that affect nanoparticles' bioavailabilities beyond sizedependent effects. We end the review by proposing a framework towards more quantitative approaches and by highlighting promising techniques to guide future research in this exciting field.

“…Microbes exchange electrons with extracellular minerals in a number of ways including conductive appendages and chelating compounds, which can result in mineral dissolution ( Shi et al, 2016 ). The active dissolution of minerals by microbial communities can enhance the mobilization of elements, thus altering local fluid chemistry ( Ehrlich, 1996 ; Yan et al, 2019 ); however, the specific mechanisms for and products of these mineral transformations depend upon the local geochemistry and metabolic interplay between the attached and planktonic communities ( Kwon et al, 2014 ). Given that continental subsurface biofilms likely comprise as much as 20-80% of total subsurface biomass (as many as 2.4 × 10 29 cells) ( Magnabosco et al, 2018 ; Flemming and Wuertz, 2019 ), these mineral transformations may occur on large scales and critically affect subsurface biogeochemical cycles.…”

Rock-Hosted Subsurface Biofilms: Mineral Selectivity Drives Hotspots for Intraterrestrial Life

The continental deep subsurface is likely the largest reservoir of biofilm-based microbial biomass on Earth, but the role of mineral selectivity in regulating its distribution and diversity is unclear. Minerals can produce hotspots for intraterrestrial life by locally enhancing biofilm biomass. Metabolic transformations of minerals by subsurface biofilms may occur widely with the potential to significantly impact subsurface biogeochemical cycles. However, the degree of impact depends upon the amount of biofilm biomass and its relationship to host rock mineralogy, estimates that are currently loosely constrained to non-existent. Here, we use in situ cultivation of biofilms on native rocks and coupled microscopy/spectroscopy to constrain mineral selectivity by biofilms in a deep continental subsurface setting: the Deep Mine Microbial Observatory (DeMMO). Through hotspot analysis and spatial modeling approaches we find that mineral distributions, particularly those putatively metabolized by microbes, indeed drive biofilm distribution at DeMMO, and that bioleaching of pyrite may be a volumetrically important process influencing fluid geochemistry at this site when considered at the kilometer scale. Given the ubiquity of iron-bearing minerals at this site and globally, and the amount of biomass they can support, we posit that rock-hosted biofilms likely contribute significantly to subsurface biogeochemical cycles. As more data becomes available, future efforts to estimate biomass in the continental subsurface should incorporate host rock mineralogy.
