Comparative analysis of antiradical and antibacterial activity of Boletus edulis basidiomycetes growing in different climatic zones

Siberian ceps (Boletus edulis) exhibit significantly higher antiradical activity compared to their counterparts from Montenegro's Durmitor National Park, with a maximum value of 75% versus 33%, respectively. This study, conducted in 2019, analyzed aqueous extracts of mushrooms from both regions using UV-visible spectroscopy and bacterial colony growth assays. The research revealed that while both Siberian and Montenegrin ceps demonstrate bacteriostatic effects against Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, and Acinetobacter baumannii after 30 minutes of extraction, prolonged extraction (over 60 minutes) shifts the effect to bacterial growth stimulation. The findings highlight the potential of Boletus edulis extracts as natural antioxidants and their complex antibacterial properties, which vary based on climatic conditions.
