Screening of Georgian Medicinal Mushrooms for Their Antibacterial Activity and Optimization of Cultivation Conditions for the Split Gill Medicinal Mushroom, Schizophyllum commune BCC64 (Agaricomycetes).

The present study aimed to evaluate the antibacterial activity (ABA) of new mushroom strains collected from the mountain and plain forests of Georgia and belonging to different taxonomic groups. Of 30 Basidiomycetes strains tested on agar plates, Schizophyllum commune BCC64 exhibited the highest inhibitory activity against Escherichia coli and Staphylococcus aureus by the diameter of inhibition zones (17 ± 1 mm and 19 ± 1 mm, respectively). Moreover, this mushroom showed strong activity against Staphylococcus enteritidis (11 mm), Pseudomonas aeruginosa (19 mm), and Salmonella epidermitidis (12 mm).
