AB Endophytic fungi were isolated from ginger (Zingiber officinale) tubers and identified through molecular characterization of ITS and 28S rRNA regions. Nine species were obtained, belonging to the genera Aspergillus, Penicillium, Plectosphaerella, and Pseudogymnoascus. Several isolates, particularly Penicillium melinii, Aspergillus ustus, and Plectosphaerella cucumerina, exhibited strong antagonistic activity against Botrytis cinerea (up to 98.6% growth inhibition), while moderate effects were observed against Colletotrichum acutatum, Staphylococcus aureus and Klebsiella pneumoniae. All isolates produced at least one extracellular enzyme, with lipolytic and cellulolytic enzymes being the most frequently observed, and showed measurable antioxidant activity (EC50 values ranging from 21.7 to 673.6 µg/mL). P. melinii and P. cucumerina demonstrated the highest radical scavenging capacities. These findings reveal the multifunctional potential of ginger-associated endophytic fungi as sustainable sources of bioactive compounds, with promising applications in biocontrol, food preservation, and industrial biotechnology.
