“…The mechanism of uranium phosphate biomineralization was not established although it was hypothesized that available phosphate ligands could arise from the action of fungal acid phosphatases on organic P‐containing substrates (Fomina et al ., ). The ability of fungi to release P from inorganic sources is well known, this ability being a ubiquitously found property especially in mycorrhizal fungi (Gadd, 2007; 2010), and such release can result in the formation of secondary mycogenic metal phosphates (Fomina et al ., 2007a,b; 2008; Gadd, ; Rhee et al ., 2012; 2014a,b). This has been shown for lead where fungal biodeterioration can result in pyromorphite (Pb 5 [PO 4 ] 3 X [X = F,Cl or OH]) formation (Rhee et al ., 2012; 2014a,b).…”

“…Brown and G. Smith. The fungal species selected have been previously demonstrated to be efficient in mineral dissolution and toxic metal transformations (Fomina et al ., 2007a,b; 2008; Gadd, ; Rhee et al ., 2012; 2014a,b; Wei et al ., ). The fungi were routinely maintained on 20 cm 3 modified MCD amended with 10 mM glycerol 2‐phosphate disodium salt hydrate (C 3 H 7 Na 2 O 6 P·xH 2 O) (G2P), as sole P source, in 90 mM diameter Petri dishes and grown at 25°C in the dark.…”

Geoactive soil fungi were investigated for phosphatase-mediated uranium precipitation during growth on an organic phosphorus source. Aspergillus niger and Paecilomyces javanicus were grown on modified Czapek-Dox medium amended with glycerol 2-phosphate (G2P) as sole P source and uranium nitrate. Both organisms showed reduced growth on uranium-containing media but were able to extensively precipitate uranium and phosphorus-containing minerals on hyphal surfaces, and these were identified by X-ray powder diffraction as uranyl phosphate species, including potassium uranyl phosphate hydrate (KPUO6 .3H2 O), meta-ankoleite [(K1.7 Ba0.2 )(UO2 )2 (PO4 )2 .6H2 O], uranyl phosphate hydrate [(UO2 )3 (PO4 )2 .4H2 O], meta-ankoleite (K(UO2 )(PO4 ).3H2 O), uramphite (NH4 UO2 PO4 .3H2 O) and chernikovite [(H3 O)2 (UO2 )2 (PO4 )2 .6H2 O]. Some minerals with a morphology similar to bacterial hydrogen uranyl phosphate were detected on A. niger biomass. Geochemical modelling confirmed the complexity of uranium speciation, and the presence of meta-ankoleite, uramphite and uranyl phosphate hydrate between pH 3 and 8 closely matched the experimental data, with potassium as the dominant cation. We have therefore demonstrated that fungi can precipitate U-containing phosphate biominerals when grown with an organic source of P, with the hyphal matrix serving to localize the resultant uranium minerals. The findings throw further light on potential fungal roles in U and P biogeochemistry as well as the application of these mechanisms for element recovery or bioremediation.

“…In addition to the loss of the metallic materials, Pb cations enter the environment at a weathering rate of approximately 1–5% per year, which causes serious environmental risk to soil system . The migration of Pb leachate through the liner material into underlying aquifers has caused major public health concern . Pb has hence been one of the most common hazardous heavy metals …”

Fungi play a significant role in biological corrosion of metal materials. We studied the biocorrosion of lead foils under incubation of Aspergillus niger (A. niger). Multiple techniques, for example, scanning electron microscopy (SEM), diffuse reflectance infrared Fourier transform spectroscopy (DRIFT), and Raman imaging and scanning electron microscopy (RISE), were applied in this study. SEM confirmed the normal growth of the fungus on Pb foil surface, either above or under the solid medium surface. In addition, SEM‐energy dispersive spectrometer confirmed the formation of the secondary Pb mineral particles after incubation, which had variable morphologies. DRIFT was able to show changes of compounds formed on the surface of Pb foils. However, it cannot exactly identify the mineral phase. RISE technology offered both morphological and spectral information of the formed Pb mineral. Three dominant Raman peaks at ~1,440, ~1,480, and ~1,590 cm−1 indicated that the secondary mineral was lead oxalate. Raman mapping further demonstrated the distribution of Pb oxalate architecture. This study first applied RISE to investigate the biocorrosion of metals by fungi.

The experiments conducted by several groups highlighted that the fungi such as Aspergillus terrus, Trichoderma viride (Joshi, Swarup, Maheshwari, Kumar, & Singh, 2011), and Paecilomyces javanicus (Rhee, Hillier, Pendlowski, & Gadd, 2014) have the ability to convert as much as 60 mg/g of lead (Pb) to nonhazardous minerals, such as pyromorphite. A similar process, termed biomachining, was developed and reported recently for tin (Sn), copper (Cu), aluminium (Al), and nickel (Ni) using A. niger (Jadhav & Hocheng, 2014).…”

Microbial-influenced corrosion (MIC) has been known to have economic, environmental, and social implications to offshore oil and gas pipelines, concrete structures, and piped water assets. While corrosion itself is a relatively simple process, the localised manner of corrosion makes in situ assessments difficult. Furthermore, corrosion assessments tend to be measured as part of a forensic investigation. Compounding the issue further is the impact of microbiological/biofilm processes, where corrosion is influenced by the complex processes of different microorganisms performing different electrochemical reactions and secreting proteins and metabolites that can have secondary effects. While traditional microbiological culture-dependent techniques and electrochemical/physical assessments provide some insight into corrosion activity, the identity and role of microbial communities that are related to corrosion and corrosion inhibition in different materials and in different environments are scarce. One avenue to explore MIC and MIC inhibition is through the application of omics-based techniques, where insight into the bacterial population in terms of diversification and their metabolism can be further understood. As such, this paper discusses the recent progresses made in a number of fields that have used omics-based applications to improve the fundamental understanding of biofilms and MIC processes.
