In this study, we investigated the biostimulant effect of fungal culture filtrates obtained from and on growth performance and metabolomic traits of chicory () plants. For the first time, we showed that culture filtrate exerts a direct plant growth-promoting effect through an increase of biomass, both in shoots and roots, and of the leaf area. Conversely, no significant effect on morphological traits and biomass yield was observed in plants treated with culture filtrate.

Glyphosate is the most commonly used herbicide worldwide. Its improper use during recent decades has resulted in glyphosate contamination of soils and waters. Fungal bioremediation is an environmentally friendly, cost effective, and feasible solution to glyphosate contamination in soils.

Article Synopsis
  • DDT was widely used as an insecticide but is now banned in most industrialized countries due to its environmental persistence, leading to long-term contamination.
  • Research in Poland identified 38 fungal taxa from DDT-contaminated soils; two strains showed significant tolerance to DDT and high metabolic versatility in using various carbon sources.
  • These fungi may offer potential solutions for bioremediation of DDT-contaminated sites, highlighting the need for further studies into their ecological functionality and environmental impacts.

The study of the soil microbial community represents an important step in better understanding the environmental context. Therefore, biological characterisation and physicochemical integration are keys when defining contaminated sites. Fungi play a fundamental role in the soil, by providing and supporting ecological services for ecosystems and human wellbeing.

For decades, human activities, industrialization, and agriculture have contaminated soils and water with several compounds, including potentially toxic metals and organic persistent xenobiotics. The co-occurrence of those toxicants poses challenging environmental problems, as complicated chemical interactions and synergies can arise and lead to severe and toxic effects on organisms. The use of fungi, alone or with bacteria, for bioremediation purposes is a growing biotechnology with high potential in terms of cost-effectiveness, an environmental-friendly perspective and feasibility, and often representing a sustainable nature-based solution.

Modern agriculture is dependent on phosphate rock (PR), which is a nonrenewable resource. Improvement of phosphorus (P) availability for crops in agricultural soils represents a key strategy to slow down the depletion of PR. The aim of this study was to identify potential P biofertilisers among saprotrophic fungal species.

The saprotrophic fungus Penicillium griseofulvum was chosen as model organism to study responses to a mixture of hexachlorocyclohexane (HCH) isomers (α-HCH, β-HCH, γ-HCH, δ-HCH) and potentially toxic metals (vanadium, lead) in solid and liquid media. The P. griseofulvum FBL 500 strain was isolated from polluted soil containing high concentrations of HCH isomers and potentially toxic elements (Pb, V).

Fungi cover a range of important ecological functions associated with nutrient and carbon cycling in leaf litter and soil. As a result, research on existing relationships between fungal functional diversity, decomposition rates and competition is of key interest. Indeed, availability of nutrients in soil is largely the consequence of organic matter degradation dynamics.

Article Synopsis
  • Researchers investigated the role of specific soil fungi in releasing inorganic phosphate and removing lead from contaminated media, using organic phosphate sources.
  • The fungi Aspergillus niger and Paecilomyces javanicus effectively liberated inorganic phosphate while growing on lead-containing substrates, leading to significant lead precipitation and the formation of minerals like pyromorphite and lead oxalate.
  • The study highlights two main mechanisms of lead biomineralization influenced by the fungi's nutritional preferences, contributing to a better understanding of bioremediation strategies and the ecological roles of soil fungi.

Article Synopsis
  • β-Hexachlorocyclohexane (β-HCH) is a harmful environmental pollutant that can negatively impact human health and ecosystems, prompting research into its biodegradation using fungi.
  • The study focused on the soil fungus Penicillium griseofulvum, which was found to tolerate β-HCH and grow in nutrient-limited conditions, indicating its potential for environmental remediation.
  • Analysis showed that P. griseofulvum successfully degraded β-HCH, reducing its concentration by at least 18.6%, and produced benzoic acid derivatives as byproducts, suggesting a viable biodegradation pathway linked to fungal metabolism.

Fungi play important roles in biogeochemical processes such as organic matter decomposition, bioweathering of minerals and rocks, and metal transformations and therefore influence elemental cycles for essential and potentially toxic elements, e.g., P, S, Pb, and As.

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 .

Saprotrophic fungi were investigated for their bioweathering effects on the vanadium- and lead-containing insoluble apatite group mineral, vanadinite [Pb5 (VO4 )3 Cl]. Despite the insolubility of vanadinite, fungi exerted both biochemical and biophysical effects on the mineral including etching, penetration and formation of new biominerals. Lead oxalate was precipitated by Aspergillus niger during bioleaching of natural and synthetic vanadinite.
