Súhrn: This study investigated the free radical-scavenging activity (RSA) using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical, total phenolic content and the potential of anti-quorum sensing (anti-QS) properties of Agaricus bisporus (white button mushroom), Clitocybe nuda (wood blewit), Lactarius volemus (weeping milk cap), Macrolepiota procera (parasol mushroom) and Xerocomellus chrysenteron (red cracking bolete) water extracts. The anti-QS activity of mushroom extracts was determined by a chemiluminescent reporter strain E. coli JM109 (containing a recombinant pSB 1142 plasmid) in white microtitre plates. All five water extracts showed significant antioxidant activity (in the range of 68.5–90.5 %) and anti-QS activity (594–5772 relative light units RLU for P. aeruginosa 119 and 4–531 RLU for P. aeruginosa 44).
