F USARIUM oxysporum strain F2 was isolated from the soil. It was morphologically and molecularly identified. The isolate showed promising thermotolerance characteristics. This was shown through the production of permanent proteins after 120min of pre-thermal exposure at 40°C, as detected by SDS-PAGE. On the other hand, the RAPD marker revealed higher genetic variations produced by Fusarium oxysporum than the ISSR marker. Thirteen ISSR primers yielded 137 total bands, of which 81 were polymorphic bands with a percentage of 59.12%. While 18 RAPD primers yielded 223 total bands, 141 of which were polymorphic bands with a percentage of 63.23%. Notably, elevated temperatures triggered the isolate to enhance the production of hydrolytic enzymes. Fusarium oxysporum strain F2 produced more cellulolytic and pectinolytic enzymes until 120min pre-thermal exposure at 40°C, displaying 3.262 and 1.797 (IU/mL), with corresponding percentages of activation 82.031% and 73.288%, respectively. This promising yield of cellulolytic activity could be employed in biofuel production.

S ILVER and gold have long been utilized as currency; they have also been used for clinical instruments for their antibacterial properties, which occur in metallic and salt structures. The utilization of metallic nanoparticles for restorative and sterile applications has become more acceptable recently because of advances in nanoscience and nanotechnology. Expanding the utilization of metallic nanoparticles in human well-being is an essential issue. As a general rule, the potential harmfulness of metallic nanoparticles requires safe application tactics. Nanocomposites are an excellent solution since the flexibility of the nano-objects is limited, but their mobility is maintained. This review aims to enhance the current understanding of the effectiveness of nanomaterials in eliminating dangerous bacterial species, improving human health and eliminating many diseases that may appear in the future. These materials will significantly and effectively reduce the future spread of diseases caused by the main bacteria that are resistant to traditional antibiotic treatments.
