In last decades, bacterial resistance to first choice
antibiotics has been drastically increasing, therefore,
the research of new antimicrobial substances
is of great importance. This rising problem
with bacterial resistance to existing antibiotics
affects not only the health care institutes but also
food plants. S. aureus and S. enteritidis pose a
number of challenges to the food industry and
cause foodborne illness in humans. In addition,
due to their favourable elemental composition,
oyster mushrooms (Pleurotus sp.) are a reservoir
of bioactive compounds that give them remarkable
antibacterial potential. P. ostreatus is of
great economic importance and is the second
most cultivated edible mushroom, therefore information
about its possible targets on bacterial
cells is of great importance for use as a dietary
supplement or medicinal purposes. The results of
the antibacterial assay showed that tested bacterial
strains were susceptible to the methanol extract of P. o...streatus (PoME), while microbicidal
activity was only detected against Gram-positive
bacteria. Scanning electron microscopy (SEM)
micrographs suggested that extract acted on
cytoplasmic membrane of S. aureus, while the
cell envelope of S. Enteritidis was the most likely
target. Natural extracts may outperform individual
bioactive compounds due to the synergistic
interaction between the metabolites, which can
enhance the effects of the individual components.
Extracts rich in antibacterials are emerging
as alternatives to synthetic antibiotics in the food
and health sectors. Among these, crude mushroom
extracts are particularly sought after for
their diverse bioactive ingredients, as they can
combat resistant strains of bacteria due to their
different targets and modes of action. PoME can
be used as an effective antimicrobial agent, suitable
for applications aiming to eradicate foodborne
pathogens, thus enhancing food safety.
