“…Moreover, T. viride bioaccumulates copper as a layer on the cell wall surface as well. Another mechanism involved in copper tolerance showed that enzymes such as catalase and peroxidase increase their activity in the presence of copper, while the malondialdehyde (MDA) levels decrease (Juniors et al, 2020 ).…”

Due to their unique properties and functionalities, nanomaterials can be found in different activities as pharmaceutics, cosmetics, medicine, and agriculture, among others. Nowadays, formulations with nano compounds exist to reduce the application of conventional pesticides and fertilizers. Among the most used are nanoparticles (NPs) of copper, zinc, or silver, which are known because of their cytotoxicity, and their accumulation can change the dynamic of microbes present in the soil. In agriculture, Trichoderma is widely utilized as a safe biocontrol strategy and to promote plant yield, making it susceptible to be in contact with nanomaterials that can interfere with its viability as well as its biocontrol and plant growth promotion effects. It is well-known that strains of Trichoderma can tolerate and uptake heavy metals in their bulk form, but it is poorly understood whether the same occurs with nanomaterials. Interestingly, Trichoderma can synthesize NPs that exhibit antimicrobial activities against various organisms of interest, including plant pathogens. In this study, we summarize the main findings regarding Trichoderma and nanotechnology, including its use to synthesize NPs and the consequence that these compounds might have in this fungus and its associations. Moreover, based on these findings we discuss whether it is feasible to develop agrochemicals that combine NPs and Trichoderma strains to generate more sustainable products or not.

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.
