“…Entomopathogenic fungi can be used for heavy metal removal from the environment by improving the phytoremediation properties of plants (Farias et al 2019). Even trace amounts of metals in the environment can have an adverse effect on soil, the ecosystem, water circulation, and elements in the environment as well as on human and animal health.…”

“…EPF are not only insect pathogens, but they are also associated with plant rhizosphere, thereby promoting plant growth. Farias et al (2019) investigated the effect of fungal consortium containing four species of EPF (B. bassiana, M. anisopliae, P. chlamydosporia, and P. lilacinum) on the ability of Jacaranda mimosifolia to absorb Cu (II), Zn (II), and Mn (II). After 45 days of experiments, it was found that the use of the fungal preparation in combination with biochar caused an increase in the mass of roots and shoots of J. mimosifolia, intensified the translocation of metals from roots to shoots, and inhibited the leaching of metals from plant tissues, which resulted in an increased concentration of these metals in J. mimosifolia tissues.…”

Entomopathogenic fungi (EPF) are microorganisms that cause fatal diseases of arthropods. The infection process involves several stages that consist of direct contact of the fungus with the surface of the cuticle of the attacked insect. The factors that determine the effectiveness of the infection process include lytic enzymes, secondary metabolites, and adhesins produced by EPF. Because of their high insecticidal effectiveness, these fungi are commonly used as biopesticides in organic farming. As the environment and farmlands are contaminated with many compounds of anthropogenic origin (e.g., pesticides), the effects of these toxic compounds on EPF and the mechanisms that affect their survival in such a toxic environment have been studied in recent years. This review presents information on the capacity of EPF to remove toxic contaminants, including alkylphenols, organotin compounds, synthetic estrogens, pesticides and hydrocarbons. Moreover, these fungi produce numerous secondary metabolites that can be potentially used in medicine or as antimicrobial agents. Despite their huge potential in biocontrol processes, the use of EPF has been underestimated due to a lack of knowledge on their abilities. In our work, we have presented the available data on the possibilities of the additional and unconventional use of these microorganisms.

“…Beauveria bassiana mostly colonizes aerial parts of the plant, but Metarhizium needs to compete for iron with other members of the plant root microbiome, and tolerance to metals could add additional benefit to Metarhizium symbiotic associations with plants. Farias et al [ 182 ] found that a consortium of fungal isolates ( M. anisopliae , P. chlamydosporia , B. bassiana , Purpureocillium lilacinum and Trichoderma asperella ) improved plant tolerance to heavy metals and boosted growth.…”

The genus Metarhizium and Pochonia chlamydosporia comprise a monophyletic clade of highly abundant globally distributed fungi that can transition between long-term beneficial associations with plants to transitory pathogenic associations with frequently encountered protozoans, nematodes or insects. Some very common ‘specialist generalist’ species are adapted to particular soil and plant ecologies, but can overpower a wide spectrum of insects with numerous enzymes and toxins that result from extensive gene duplications made possible by loss of meiosis and associated genome defence mechanisms. These species use parasexuality instead of sex to combine beneficial mutations from separate clonal individuals into one genome (Vicar of Bray dynamics). More weakly endophytic species which kill a narrow range of insects retain sexuality to facilitate host–pathogen coevolution (Red Queen dynamics). Metarhizium species can fit into numerous environments because they are very flexible at the genetic, physiological and ecological levels, providing tractable models to address how new mechanisms for econutritional heterogeneity, host switching and virulence are acquired and relate to diverse sexual life histories and speciation. Many new molecules and functions have been discovered that underpin Metarhizium associations, and have furthered our understanding of the crucial ecology of these fungi in multiple habitats.

“…However, the problem of soil health is critical for the suitable functioning of earthly ecosystems. As a result, even at low concentrations, it has an effect on element emissions, lowering soil productivity, ecosystem biota, uxes of elements and water, human and animal health respectively (Farias et al, 2020). It is predicted that the sewage sludge will be used for the soil in the future.…”

Green synthesis of copper nanoparticles extracted from guar seedling under Cu heavy-metal stress by Trichoderma harzianum and their bio-efficacy evaluation against Staphylococcus aureus and Escherichia coli

Copper nanoparticles were successfully synthesized with the help of the agriculturally bene cial fungus Trichoderma harzianum through a simple green and eco-friendly route. The objectives of this study were to: 1) evaluate the application of Trichoderma harzianum and assess the effect of guar plant cultivation on heavy metal contaminated lands of copper in municipal and industrial wastewaters, and 2) develop a method to increase the antibacterial effects on the risk of two bacteria (Staphylococcus aureus and Escherichia coli). Two factors were investigated: 1) two copper (Cu) levels, Natural Hoagland Arnold solution as a control, and application of 100 μlit Cu in Hoagland Arnold solution, and 2) two bio-fertilizer levels, no application as a control, and fungus application. Biosynthesized nanoparticles were characterized using transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-Ray Diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) analysis. Diffusion disk, minimum inhibitory concentration (MIC) and minimum bacterial concentration (MBC) were used for the antibacterial tests. The results of TEM and SEM showed that the copper nanoparticles synthesize from guar extract, had a spherical structure, and a size of approximately 20 nm. The crystal structure from the XRD analysis, con rmed the synthesized particles as copper nanoparticles. The formation of Cu-NPs was con rmed by the FTIR analysis. Furthermore, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of copper nanoparticles towards bacterial growth were evaluated. The copper nanoparticles and Trichoderma harzianum fungi presented antibacterial activity against Gram positive and Gram negative bacteria. The results suggested that green synthesis of nanoparticles using guar extracts can increase their antibacterial effect. The effect of copper nanoparticles and Trichoderma harzianum fungi on biochemical properties of guar was also investigated. The results showed that the highest antioxidant enzymatic activity and proline amino acid were obtained at 100 μlit Cu and T. harzianum fungi application. Moreover, the results suggested that the use of T. harzianum fungi can be useful in increasing the resistance to heavy metal stress in plants by increasing the activity of some antioxidant enzymes and secondary metabolites.
