Mushrooms
could be used as a potential means of producing natural antioxidants and
antimicrobials. To obtain fungal
biomass in submerged culture is an easy and rapid method. For this reason,
biomasses of Pleurotus species which grown on liquid media were used to
prepare hot water extracts and their antioxidant and antibacterial properties
were determined. The highest total phenolic content was determined in P.
ostreatus extract (9.14 mg.g-1 dry weight of extract) whereas Pleurotus sajor-caju gave highest
reading of total flavonoid content (3.10 mg.g-1 dry weight of
extract). In
the scavenging effect of DPPH radical test, P. sajor-caju showed the
highest activity potential (69.67%). Mycelia extracts from Pleurotus species showed the antibacterial
activity against the Gram negative and Gram positive bacteria (plant and human
pathogens). Based on the results obtained, each extract from the five species Pleurotus
(P. florida, P. citrinopileatus, P. sajor-caju, P. ostreatus
and P. eryngii) showed antioxidant and antibacterial properties, and
could be used in the formulation of nutraceuticals. Furthermore, the
results presented in this work demonstrated that extracts were capable of inhibiting the in vitro growth
of Helicobacter pylori.
