Title	Proteomic approach for the green synthesis of nanoparticles by Trichoderma harzianum
Description	Compared with other organisms or conventional synthesis methods, the biogenic synthesis of nanoparticles from fungi has multiple advantages. Although the process is simple, nontoxic, and inexpensive, the synthesis mechanism remains largely undetermined. In this research, we focused on the proteins present in the aqueous filtrate of a native strain of Trichoderma harzianum, which is used as a reducing and stabilizing medium in the biogenic synthesis of zinc oxide nanoparticles (ZnONPs) and iron oxide nanoparticles (FeONPs). SDS‒PAGE analysis revealed distinct protein profiles in the culture medium (CM) and aqueous filtrate (AF), identifying through proteomic approach approximately 99 proteins in the CM and 304 in the AF, with 91% of the proteins only present in AF. From AF functional annotation classified the proteins mainly involved in metabolic processes and stress responses, with a notable presence of oxidoreductases. Successfully, ZnO and FeO NPs were synthesized from the aqueous filtrate and which presented a bouquet or irregular morphology. Characterization by TEM and EDS confirmed the successful synthesis of ZnONPs with an average size of 660 ± 109 nm and FeONPs with an average size of 18 ± 7 nm. Dynamic light scattering (DLS) analysis indicated that the ZnONPs presented low size variability and good stability, whereas the FeONPs presented a bimodal size distribution. Both NPs have thermal stability at 400 ºC meanwhile X-ray diffraction (XRD) confirmed the crystalline nature of both types of nanoparticles. FTIR analysis revealed organic compounds that could act as stabilizing agents, suggesting the presence of proteins involved in nanoparticle synthesis. This research is the first to conduct a proteomic analysis of the aqueous filtrate of T. harzianum with applications in the biogenic synthesis of NPs.
