Pleurotus (oyster mushroom) species have been utilized by human cultures everywhere on the world for their dietary benefit, medicinal properties, and other beneficial impacts. White oyster mushroom (Pleurotus florida) is an edible mushroom that gained popularity due to its nutritional values, low production cost and ease of cultivation. In this study, the antioxidant activities were evaluated using Folin-Ciocalteu method, DPPH radical scavenging activity and ferric reducing antioxidant power and the antimicrobial activities were evaluated using agar disk-diffusion method. Out of the 10 concentrations tested for the antioxidant properties, concentration of 1mg/ml of the IPS extract showed the higher total phenolic content and ferric reducing antioxidant power, while for the DPPH radical scavenging activity concentration of 0.2mg/ml of IPS extract showed the highest scavenging activity. For the antimicrobial evaluation, out of the 6 concentrations tested, there was no antimicrobial activity against S.aureus, P. aeruginosa and E.coli for all. In conclusion, Pleurotus florida mushroom has shown no antimicrobial effects with water as the solvent. On the other hand, it has shown intermediate antioxidant effects. Further studies should be done with different solvents to evaluate the effects of Pleurotus florida mushroom.
