Phytochemical Profile and Antimicrobial Activities of Edible Mushroom Termitomyces striatus

Summary

Researchers studied an edible mushroom called Termitomyces striatus traditionally consumed in Africa and Asia to understand its disease-fighting properties. They found that extracts from this mushroom contain beneficial compounds that can kill harmful bacteria and fungi in laboratory tests. The dichloromethane extract was the most effective, showing strong activity against multiple disease-causing bacteria and the yeast Candida albicans. This suggests the mushroom could potentially be developed into new natural antimicrobial treatments.

Background

Termitomyces striatus is an edible mushroom from the family Lyophyllaceae that grows wildly in Africa and Asia. Mushrooms and their active components have demonstrated beneficial effects on various biological systems, including antimicrobial properties. This study investigated the phytochemical composition and antimicrobial activities of T. striatus extracts.

Objective

To determine the qualitative phytochemical composition of aqueous extracts of T. striatus and evaluate the antimicrobial effects of aqueous, methanolic, and dichloromethane extracts against various bacterial and fungal strains including Gram-negative bacteria (E. coli, P. aeruginosa), Gram-positive bacteria (B. subtilis, S. aureus), and fungi (C. albicans, S. cerevisiae).

Results

Phytochemical screening revealed the presence of alkaloids, flavonoids, steroids, sterols, saponins, phenols, carbohydrates, and proteins. All three extracts exhibited antibacterial activity against tested bacterial strains, with DCM extract showing the highest effects. All extracts showed antifungal effects against C. albicans, but methanol and aqueous extracts did not inhibit S. cerevisiae growth.

Conclusion

T. striatus extracts demonstrate potent antibacterial activity against both Gram-negative and Gram-positive bacteria, as well as antifungal effects against C. albicans. The extracts represent a promising source of novel antimicrobial and antifungal agents with potential therapeutic applications.
