SOME BIOACTIVE PROPERTIES OF WILD AND COMMERCIAL MUSHROOM SPECIES

Abstract

In this study, the protein and total phenolic contents of some commercially cultivated ( Agaricus bisporus , Pleurotus ostreatus ) and wild mushrooms ( Amanita caesarea , Fistulina hepatica , Meripilus giganteus ) were determined. Antioxidant and antimicrobial properties of these mushrooms against Escherichia coli , Staphylococcus aureus , Enterococcus faecalis , Klebsiella pneumoniae , Salmonella typhimurium , Acinetobacter haemolyticus , Proteus mirabilis , Pseudomonas aeruginosa and Candida albicans were also investigated. The protein contents, total phenolic contents and antioxidant activities of the mushrooms were found in the range of 11.00 - 25.1%, 1.111 - 3.858 mg GAE g -1 , and 1.528 - 9.340 μmol FeSO 4 ·7H 2 O g -1 , respectively. Meripilus giganteus had higher protein than all the tested mushrooms. The highest total phenolic content was detected in Agaricus bisporus obtained from B company (3.858 mg GAE g -1 ), whereas the lowest total phenolic content was observed in Meripilus giganteus (1.111 mg GAE g -1 ). Total phenolic and antioxidant properties of mushrooms were found significantly different (P<0.05) by Duncan’s multiple range test. Methanolic extracts of the tested mushrooms showed no inhibitory activity against bacteria and yeast.
