Fungi may have the greatest geochemical influence within the terrestrial environment, but they are also important in the aquatic environment and are significant components of the deep subsurface, extreme environments, and habitats polluted by xenobiotics, metals, and radionuclides.

Colonization and bioweathering of monazite by Aspergillus niger: solubilization and precipitation of rare earth elements.

Correlation analysis suggested that citric acid was more effective than oxalic acid in REE mobilization, although the higher concentration of oxaloic acid also implied complexant activity, as well as the prime role in REe-oxalate precipitation.

Chemical and Physical Mechanisms of Fungal Bioweathering of Rock Phosphate

Findings emphasize the important role of fungi in P cycling, with active participation in the transformation of mineral phosphates through physicochemical mechanisms and secondary oxalate biomineral formation.

Fungi and Arsenic: Tolerance and Bioaccumulation by Soil Saprotrophic Species

Four soil saprotrophic fungi isolated from soils with naturally high arsenic concentrations were tested for their ability to tolerate different sodium arsenite concentrations and accumulate As in different cultural conditions and produced siderophores with different affinities for Fe and As.

Metal bioavailability and the soil microbiome

Fungi, P-Solubilization, and Plant Nutrition

The role of fungi in P-solubilization and plant nutrition will be presented with a special emphasis on their production and application, and further lines of research are discussed that may clarify doubts in this field or open new perspectives on using the microbial and particularly fungal P- solubilizing potential in accordance with the principles of the sustainability and circular economy.

Rare earth contamination of edible vegetation: Ce, La, and summed REE in fungi

Abstract The increasing and diversified use of rare earth elements (REE) is considered a potential source of pollution of environmental media including soils. This work documents critically overview…

Regulation of fungal decomposition at single-cell level

A method based on infrared spectroscopy that allows the direct, in-situ chemical imaging of the decomposition activity of individual hyphal tips is developed that may help filamentous fungi to cope with heterogeneous and constantly changing soil environments.

Influences of phosphate addition on fungal weathering of carbonate in the red soil from karst region.

Colonization, penetration and transformation of manganese oxide nodules by Aspergillus niger

These findings contribute to an understanding of environmental processes involving insoluble manganese oxides, with practical relevance to chemoorganotrophic mineral bioprocessing applications, and represent the first demonstration of fundamental direct and indirect interactions between geoactive fungi and manganes nodules.
