Evaluation of Antibiofilm, Antimicrobial, Cytotoxic and Antioxidant Effects of Some Wild Mushroom Species.

In this study, ethanol extracts of some wild mushroom species, in the phylum Basidiomycota, (Armillaria mellea (Vahl) P. Kumm., Infundibulicybe geotropa (Bull.) Harmaja, Leucopaxillus gentianeus (Quél.) Kotl. and Trametes versicolor (L.) Lloyd) were tested for their antioxidant, antimicrobial, antibiofilm, and cytotoxic activities. Mushroom samples showed low antimicrobial activity on Enterococcus faecalis and Staphylococcus aureus, while biofilm inhibitory activity on test microorganisms ranged from 24.6% to 80.5%. At the end of the antioxidant activity studies, A. mellea was the mushroom sample having the highest DPPH radical scavenging capacity (0.105±0.001 mg/mL) whereas T. versicolor was the one having the highest iron (III) ion reducing power (40.709±0.003 µg TE/100g). The highest polyphenol content was observed in T. versicolor (29.916±0.002 mg GAE/100g) samples, and the lowest in A. mellea (9.5±0.006 mg GAE/100g) samples. The cytotoxic effects of the samples were tested on MCF-7, MDA-MB-231 (breast cancer) and L929 (mouse fibroblast) cell lines using the MTT method. As a result, it was observed that A. mellea and T. versicolor samples were more effective on the MCF-7 cell line, and A. mellea on MDA-MB-231 cell line. [ABSTRACT FROM AUTHOR]
