Muscodor albus and its biological promise

Area of Science:

• Microbiology
• Mycology
• Biochemistry

Background:

• Endophytic fungi reside within plant tissues, offering potential for novel bioactive compound discovery.
• The search for sustainable alternatives to chemical pesticides and fumigants is critical in agriculture and waste management.

Purpose of the Study:

• To identify and characterize a novel endophytic fungus producing bioactive volatile organic compounds (VOCs).
• To evaluate the antimicrobial and pesticidal properties of the fungal VOCs.
• To explore potential applications of these VOCs in sustainable pest and disease management.

Main Methods:

• Isolation and identification of endophytic fungi from Cinnamomum zeylanicum.
• Analysis of volatile organic compounds (VOCs) using Gas Chromatography/Mass Spectrometry (GC/MS).
• Verification of VOC identity using artificial compound mixtures.
• Bioassays to assess the efficacy of VOCs against fungal, bacterial, nematode, and insect pathogens.

Main Results:

• Discovery of a novel fungal genus, Muscodor albus, as an endophyte.
• Identification of a complex mixture of VOCs, including alcohols, acids, esters, ketones, and lipids.
• Demonstration that the fungal VOCs exhibit broad-spectrum lethality against plant and human pathogens, nematodes, and insects.
• Artificial VOC mixtures replicated the biological activity of the naturally produced compounds.

Conclusions:

• Muscodor albus produces highly bioactive VOCs with significant antimicrobial and pesticidal properties.
• These VOCs represent a promising source for developing eco-friendly "mycofumigation" strategies.
• Potential applications include agricultural pest control, soil-borne disease management, and waste treatment.
