“…Conversely, the oyster mushroom ethyl acetate extract displayed inhibitory activity against E. coli, with an observed inhibition zone of 12.00 mm. In contrast to the findings of this study, Han et al 24 reported contradictory results regarding the efficacy of 95% ethanolic oyster mushroom extract in inhibiting pathogenic bacterial growth. This discrepancy could potentially arise from variations in extract concentrations utilized in the experiments, which might have influenced the inhibition outcomes for certain pathogens.…”

“…This discrepancy could potentially arise from variations in extract concentrations utilized in the experiments, which might have influenced the inhibition outcomes for certain pathogens. Consistent with the observations of Han et al, 24 the ethyl acetate extract from oyster mushrooms exhibited efficacy in inhibiting E. coli growth, marked by an inhibition zone of 8.33 mm. It is noteworthy that the 95% ethyl acetate extract of oyster mushroom demonstrated a broad spectrum of inhibitory activity against various bacterial strains, including B. cereus, E. cloacae, P. mirabilis, P. aeruginosa, S. aureus, S. marcescens, and S. typhi.…”

This study investigated the antibacterial properties of Pleurotus ostreatus (Jacq. Ex Fr.) P. Kumm. extracts against various pathogenic bacteria. The fruiting bodies of fresh oyster mushrooms were collected from Mae Phai Boon Mushroom Farm in Ban Thung Nang Rao, Mueang District, Mahasarakham Province, and subjected to extraction using 95% ethanol and 95% ethyl acetate solvents. The effectiveness of the extracts in suppressing the proliferation of pathogenic microorganisms, encompassing Bacillus cereus, Enterobacter cloacae, Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella typhi, Serratia marcescens, and Staphylococcus aureus, was assessed through the utilization of the paper disk diffusion technique. The results revealed that the crude extract obtained from the 95% ethanol solvent exhibited significant inhibitory effects against B. cereus, E. cloacae, P. aeruginosa, S. marcescens, and S. typhi, yielding inhibition zone diameters from 9.22 to 12.33 mm. In contrast, the crude extract from the 95% ethyl acetate solvent showed inhibitory activity only against E. coli, revealing an inhibition zone diameter of 12.00 mm. Additionally, the determination of the minimum inhibitory concentration (MIC) of the 95% ethanol crude extract against P. aeruginosa and S. marcescens established a value of 150 mg/ml, and concomitantly, the minimal bactericidal concentration (MBC) was also established at 150 mg/ml. However, it was observed that the 95% ethanol crude extract at a concentration of 15 mg/ml was incapable of suppressing the proliferation of E. coli in the MIC evaluations. These findings imply that the extracts originating from P. ostreatus possess inherent capacity as organic antibacterial agents targeting specific pathogenic bacteria. Therefore, these findings justify the necessity for additional scrutiny into their conceivable utilities within the domains of medicine and food preservation.

“…Among the metabolites, phenolic and flavonoid compounds show excellent antioxidant capacity (Barros et al, 2007, De Silva et al, 2013, Yildiz et al, 2015. These metabolites can be extractable (with water or different organic solvents) from both mycelial biomass and fruit body of mushrooms (Lee et al, 2007, Han et al, 2015 and they are sold as a capsule or tablet for diseases prevention (De Silva et al, 2013).…”

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.

“…Oyster mushrooms consist of two extracts, mainly petroleum ether and ethanol, which are evidenced for antibacterial properties against gram positive and gram-negative bacteria (Pauliic and Dorica, 2013). Acetone and Ethyl acetate extracts of the oyster mushroom illustrated the antibacterial activity against B. subtilis and E. coli(Han et al, 2015). Oyster mushrooms consist mainly β-D-Glucan as a secondary metabolite which have antibacterial activity(Cohen et al, 2002).…”

Nowadays, multidrug antimicrobial resistance is a very common issue globally. Antimicrobial resistance is fueling the fire, and it has been noted that infectious disease incidence and deaths are rising throughout the world. Many pathogens have been reported to develop resistance to these synthetic and semi-synthetic drugs leading to minimized efficacy and resulting in substantial economic losses all over the world. A new approach for choosing natural extracts of plants and fungi as medicines and natural antibacterial agents has been developed to address this challenge. According to recent investigations and research, mushrooms and their extracts contain bioactive compounds that can be used as a natural antibacterial alternative against a number of bacterial species. In addition to having medical properties like antibacterial, anticancer, and antioxidant activity, mushrooms are a highly nutritious food source. The present study emphasized on the antimicrobial resistance, mechanisms and antibacterial properties of mushrooms.
