This study investigated the effect of different media on the production of secondary metabolites, antimicrobial, and antioxidant activity in Pleurotus species. The results showed that the metabolic pathways of Pleurotus species are strongly influenced by the chemical composition of the growth substrate. The mushroom extracts exhibited antibacterial effects against Escherichia coli and were sensitive to certain dermatophytes. Further research is needed to explore the influence of growth substrate on the antimicrobial and antioxidant properties of Pleurotus species.
Pleurotus species isolated in vitro were studied to determine the effect of different media on their production of secondary metabolites, antimicrobial, and antioxidant activity. The different metabolites among Pleurotus samples covered a total of 58 pathways. Comparisons were made between the metabolic profiles of Pleurotus spp. mycelia grown in two substrates: Potato-dextrose-agar-PDA, used as control (S1), and PDA enriched with 0.5 % of wheat straw (S2). The main finding was that the metabolic pathways are strongly influenced by the chemical composition of the growth substrate. The antibacterial effects were particularly evident against Escherichia coli, whereas Arthroderma curreyi (CCF 5207) and Trichophyton rubrum (CCF 4933) were the dermatophytes more sensitive to the mushroom extracts. The present study supports more in-depth investigations, aimed at evaluating the influence of growth substrate on Pleurotus spp. antimicrobial and antioxidant properties.
