Antibacterial Properties of Phellinus linteus Against Various Species of Bacteria

Abstract

Antimicrobial resistance (AMR) stands as a notable threat to civilization as a whole, necessitating the need for further discoveries of antibacterial agents. Phellinus linteus is a fungi whose medicinal properties have already been used though has not been thoroughly studied for its antibacterial purposes. The antibacterial activity of a commercially available P. linteus extract was observed by utilizing the Kirby-Bauer disk diffusion assay on Tryptic Soy Agar (TSA) with Staphylococcus aureus and Escherichia coli. After inoculation, the plates were incubated at 22°C and 30°C respectively for 24 hours. Antibacterial activity was observed at 22°C on TSA, with the average zone of inhibition being 10.9 ± 0.2 mm (n=248). However, no zones were observed on Mueller Hinton Agar (MHA) at either 22°C or 30°C. Additionally, no inhibition was shown against E. coli across the trials. More research is needed to further investigate the antibacterial behavior of P. linteus across a wider range of bacteria.
