Abstract(s)
The antimicrobial properties of phenolic extracts of Portuguese wild edible mushroom species (Lactarius deliciosus,
Sarcodon imbricatus and Tricholoma portentosum)
against pathogens were investigated. The minimal inhibitory
concentrations (MICs) were evaluated for the entire mushroom,
the cap and the stipe, separately; the portion of the
mushroom used proved to be influenced in the results obtained,
which are directly correlated with the content of total
phenols and flavonoids in the extracts. The growth of Grampositive
bacteria (Bacillus cereus, B. subtilis,) was well inhibited
by these mushrooms, while Escherichia coli (Gramnegative
bacteria) was resistant. The study on the antifungal
effect of these mushrooms revealed that Candida albicans
and Cryptococcus neoformans were differently inhibited for
the mushrooms used.
