“…Microorganisms, including many kinds of prokaryotes (archea and bacteria), fungi and their symbiotic associations, play an important role in the dissolution of silicates and, therefore, in the genesis of clay minerals, and in soil and sediment formation [25,69,70,75,[96][97][98][99][100][101]. The processes of biogeochemical transformation of metals and minerals, contributing to the cycling of elements on Earth, are based on two main reactions: dissolution and precipitation [24,26,[102][103][104]. Geoactive microbes are involved in both metal mobilization and immobilization: they can dissolve minerals, including clay minerals, releasing mobile metal species and associated elements into the environment, and immobilize metals by biosorption, transport, intracellular localization and accumulation by living microorganisms, redox immobilization, precipitation and biomineralization, resulting in the formation of secondary biogenic minerals (Figure 1).…”

Clay minerals are very common in nature and highly reactive minerals which are typical products of the weathering of the most abundant silicate minerals on the planet. Over recent decades there has been growing appreciation that the prime involvement of clay minerals in the geochemical cycling of elements and pedosphere genesis should take into account the biogeochemical activity of microorganisms. Microbial intimate interaction with clay minerals, that has taken place on Earth’s surface in a geological time-scale, represents a complex co-evolving system which is challenging to comprehend because of fragmented information and requires coordinated efforts from both clay scientists and microbiologists. This review covers some important aspects of the interactions of clay minerals with microorganisms at the different levels of complexity, starting from organic molecules, individual and aggregated microbial cells, fungal and bacterial symbioses with photosynthetic organisms, pedosphere, up to environmental and biotechnological implications. The review attempts to systematize our current general understanding of the processes of biogeochemical transformation of clay minerals by microorganisms. This paper also highlights some microbiological and biotechnological perspectives of the practical application of clay minerals–microbes interactions not only in microbial bioremediation and biodegradation of pollutants but also in areas related to agronomy and human and animal health.

“…Aspergillus niger ATCC 1015, Serpula himantioides, and Trametes versicolor, from the Geomicrobiology Group culture collection, were maintained on malt extract agar (MEA, lab M, Bury, UK) at 25 C in the dark. All test fungi are known to produce organic acids and secondary minerals and all have the potential to solubilize various minerals or insoluble metal compounds (Adeyemi and Gadd 2005;Ferrier et al 2019;Fomina and Gadd 2008;Gadd 2016;Gharieb et al 1998).…”

“…Being highly reactive, copper has the ability to interact with soil minerals and organic components resulting in variations of Cu bioavailability in different soils (Dumestre et al, 1999). Many fungi are able to withstand copper toxicity, and can effect biogeochemical transformations of copper through proton-and ligand-promoted metal mobilization from insoluble copper compounds with consequent metal immobilization within biomass and/or in the microenvironment (Fomina et al, 2004;2005a;2005b;2007a;Fomina and Gadd, 2007b). Fungi provide a number of ligands for both metal mobilization and immobilization.…”

Summary This work elucidates spatio‐temporal aspects of the biogeochemical transformation of copper mobilized from malachite (Cu2(CO3)(OH)2) and bioaccumulated within Aspergillus niger colonies when grown on different inorganic nitrogen sources. It was shown that the use of either ammonium or nitrate determined how copper was distributed within the colony and its microenvironment and the copper oxidation state and succession of copper coordinating ligands within the biomass. Nitrate‐grown colonies yielded ∼1.7× more biomass, bioaccumulated ∼7× less copper, excreted ∼1.9× more oxalate and produced ∼1.75× less water‐soluble copper in the medium in contrast to ammonium‐grown colonies. Microfocus X‐ray absorption spectroscopy revealed that as the mycelium matured, bioaccumulated copper was transformed from less stable and more toxic Cu(I) into less toxic Cu(II) which was coordinated predominantly by phosphate/malate ligands. With time, a shift to oxalate coordination of bioaccumulated copper occurred in the central older region of ammonium‐grown colonies.
